Ko BD, et al. The type of metal-ceramic alloys affects the bond strength of porcelain. A dentist restoring the natural look and beauty of teeth will have to consider those standards. As a control group, 7 specimens were prepared without sectioning or soldering. For the soldering methods, gas torch (G group) and infrared ray (IR group) were compared and each group was subdivided by corresponding gap distance (0.3 mm: G3 and IR3, 0.5 mm: G5, IR5). Correct occlusal relationships are part of the successful prosthetic treatment for edentulous patients. At the final stage, both groups exhibited lower mean marginal gaps than at the initial coping stage with the difference of 11.75 µm for group A and 11.94 µm for group B, but it was statistically insignificant due to high value of standard deviation. Biomechanical stress and microgap analysis of bone-level and tissue-level implant abutment structure according to the five different directions of occlusal loads Within the limitation of this study, we conclude that introduction of different height resilient material abutment with different heights i.e. 82 2 440 7518, Email: ysprosth@hanmail.net The mean ratio for the MEDIA group was 0.77, whereas that of the NON-MEDIA group was 0.88.

The ala width and distance between the tips of upper right and left canine cusps averaged (35.2 mm and 34.8 mm) but with very large individual variations. The purpose of this study is to evaluate the shear bond strength between the veneering composite resin and commercial pure (CP) Ti / Ti-6Al-4V alloy according to the method of surface treatment. This technique does not require additional clinical appointment, second impression procedure, technique sensitive manipulations with impression, or cumbersome laboratory procedures. The upper lip length was the most variable and the distance between the pupils was the most stable of the eleven facial measurements. Ruse ND, Sadoun MJ. Then, the difference in the distance between the master cast and the experimental cast were measured, and the error rate was determined. Dr. Reshad is currently on the editorial board on various journals including the Journal of Aesthetic and Restorative Dentistry. Participants answered the GPA-pa SF before restoration (T0) and 1 day (T1), 2 days (T2), 15 days (T3), 1 month (T4), and 2 months (T5) after prosthesis insertion. The bond strength data were analyzed with a one-way ANOVA and post hoc Scheffe's tests (α=.05). Experimental disc samples (20.0×3.0 mm) of tissue conditioner (GC Soft-Liner, GC cooperation, Tokyo, Japan) containing 0.1 - 3.0% silver nanoparticles (0%: control) were fabricated. Short and long term effects of additional post curing and polishing systems on the color change of dental nano-composites. The Journal of Prosthodontics is the official journal of the American College of Prosthodontists. Bone regeneration was observed in the SF and Bio-Gide®-treated groups to a greater extent than in the control group (mean volume of new bone was 5.49 ± 1.48 mm(3) at 8 weeks). However, further studies are needed on the correlation between speech intelligibility tests and objective acoustic parameters. The sputtered Ti-Ta-Nb coatings consisted of dense nanoscale grains in the range of 30 to 100 nm with alpha-Ti crystal structure. The porcelain fused to gold has been widely used as a restoration both with the natural esthetics of the porcelain and durability and marginal fit of metal casting. Dent Mater 2008;24:522–529. Fleming GJ, Awan M, Cooper PR, Sloan AJ. There were different patterns of bone regeneration between the SF membrane and the Bio-Gide® samples. There was a negative correlation between porosity formation and tensile strength in all the specimens in the test groups (P < .05). 8-9. Two tailed unpaired 't test' was used to compare marginal gaps in two groups and one way ANOVA was used to analyze marginal distortion within each group at 95% confidence interval. This variation may be associated with the lack of standardization of the preparation of teeth, computerized designing of the coping for each tooth, cement used, uniform pressure application during the cementation of the copings, sectioning of the copings and the microscopic measurements. Dent Mater 2008;24:426–431. In the first stage, the mean ISQ value for Osstell™ and Osstell™ Mentor was 70.84 and 75.09, respectively, showing a significant difference (P < .01). Significant interactions were present in L*a*b* values between the number of firings and ceramic thickness (P<.001). The impressions were made using vinyl polysiloxane (one step, heavy + light body) with an individual tray, and 10 impressions were made for each group. Many efforts have been made to minimize the duration of treatment time. However, there were no significant differences in fracture strength between the groups. Department of Biomaterials & Prosthodontics, Kyung Hee University Hospital at Gangdong, Institute of Oral Biology, School of Dentistry, Kyung Hee University, 892 Dongnam-ro, Gangdong-gu, Seoul 05278, Republic of Korea. The International Journal of Prosthodontics. Every metal-ceramic alloy used in this study showed clinically applicable bond strength with porcelain (25 MPa). The aim of this study was to identify in vitro antimicrobial activity of the tissue conditioner containing silver nanoparticles on microbial strains, Staphylococcus aureus, Streptococcus mutans and Candida albicans. L*a*b* values of the ceramic systems were affected by the number of firings (3, 5, 7, or 9 firings) (P<.001) and ceramic thickness (0.5, 1, or 1.5 mm) (P<.001). Their surfaces were treated by sandblasting, metal conditioner, TiN coating and silicoating respectively. Resin-composite blocks for dental CAD/CAM applications. © 2019 The Korean Academy of Prosthodontics. Toledano M, Osorio R, Osorio E, Fuentes V, Prati C, Garcia-Godoy F. Sorption and solubility of resin-based restorative dental materials. Specimens without the primer were also prepared and used as the controls. Depending on thermocycling treatment, each group was divided into two subgroups (n=10) and SBS was measured by applying force at the speed of 1 mm/min using a universal testing machine. Samples were placed on separate culture plate dish and microbial suspensions (100 µL) of tested strains were inoculated then incubated at 37℃. The Journal of Prosthodontics promotes the advanced study and practice of prosthodontics, implant, esthetic and reconstructive dentistry. The effective implant length and the Implant Stability Quotient (ISQ) were compared using simple linear regression analysis. The latter method is more feasible because the mobility of denture base on the mucosa in oral cavity does not permit the identification of premature contacts in centric occlusion and tooth guided eccentric excursions. After retrieval of the cast, the same impression was poured second time with the resin based resilient material to cover the facial and proximal gingival areas. Desensitizing agents were applied before cementation of crowns except for control group. Additionally, the accuracy of the implant cast was not different for the parallel and 10° mesial angulated groups. In this study, the difference in the stability of the implants was determined not by the differences in the surface treatment but by the individual specificity. And when the relationship is found out, it could be helpful to predict the prognosis of dental implants. This clinical report presents the clinical appearance and treatment approach in a case of excessive anterior teeth erosion resulted from swimming in a poorly-chlorinated swimming pool. Group 1 with the metal collar, Group 2, 3, 4 and 5 with 0 mm, 0.5 mm, 1 mm and 1.5 mm cervical metal reduction respectively were fabricated. Monomers used in resin composites: degree of conversion, mechanical properties and water sorption/solubility. An osteoblast precursor cell line, were used to evaluate the cell responses to the 3 groups. 1988. pp. Silk fibroin (SF) is a new degradable barrier membrane for guided bone regeneration (GBR) that can reduce the risk of pathogen transmission and the high costs associated with the use of collagen membranes. A device was used to standardize seating of copings on the metal die and positioning of the specimens under the microscope after each stage of fabrication. The aim of this study was to evaluate the influence of resin cement thickness on the microtensile bond strength between zirconium-oxide ceramic and resin cement. Evaluation of failure patterns indicates that most failures in the control group and IDS/SE groups were mixed, whereas failures in the DDS were interfacial. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. Geneva; Switzerland: International Standards Organization (ISO); 2009. 6385 implants were placed in 3755 patients. Considering the lower cost and lesser risk of infectious transmission from animal tissue, SF membranes are a viable alternative to collagen membranes for GBR. Ti6-Al-4V alloy disks were used as controls. The Journal of the Korea Research Society for Dental Materials; Revue odonto-implantologique; Iyo Kizai Kenkyujo hokoku. One way ANOVA and Tukey HSD post hoc tests were performed to analyze the data obtained (P < .05). After the resin cement was bonded to the zirconia using a Teflon mold, photopolymerization was carried out. A stainless steel metal model with 6 implants embedded was used as a master model. In the second stage surgery, the values of fifty implants inserted into thirty seven patients were measured. Bond strength of a resin luting agent bonded to the cleansed surface was assessed using Instron testing machine and the mode of failure noted. After air blasting of 50 µm alumina, samples were prepared by tribochemical silica coating with Rocatec™ plus. 2. An increase in number of firings resulted in significant increase in L* values for both 0.5 mm and 1.5 mm thicknesses (P<.01, P=.013); however it decreased for 1 mm thickness (P<.01). The mean ΔE value increased as the dentin ceramic thicknesses increased for zirconium-oxide based all ceramic specimens tested. The Journal of Prosthodontics promotes the advanced study and practice of prosthodontics, implant, esthetic and reconstructive dentistry. Machined surface implants were used as a control group. Little information is available about the buccal gingival level of multiple implant restorations. (SPSS Inc., Chicago, USA). Disks of commercially pure titanium, Ti-6Al-4V alloy and a cobalt-chromium alloy were cast. Four kinds of resin materials were used. The specimens were not cemented and marginal gap was measured using an image analyzing software (Imagepro Express) on the photographs captured under an optical microscope. There is a considerable variation between the measured marginal and internal gap values for the Zr copings fabricated by the (CAD4DENT-CAD/CAM). The counter die with the 0.5 mm clearance was used for fabricating the wax patterns for the metal copings. Maximum jaw opening averaged 51.2 mm which was 3.0 times larger than maximal hinge opening of 17.2 mm. Search result(s): 16. Three-point bending test was performed with universal testing machine. Restorative resin materials (Z350, Z250) showed higher VHN values than resin cement materials (VL, VLC). Internet Resource, Computer File, Journal / Magazine / Newspaper: All Authors / Contributors: Taehan Chikwa Poch'ol Hakhoe. And porcelain was applied on the center area of metal specimen. The mean shear bond strengths of control group and IDS/SE group were not statistically different from another at 14.86 and 11.18 MPa. When Model 2, 3 and 4 are compared with Model 1, they showed narrowing of stress distribution pattern in the cortical bone as the height of the polyoxymethylene resilient material abutment increases. The Ti-Ta-Nb disks and its sputtered nanoscale coatings exhibited greater hydrophilicity and rougher surfaces compared to the Ti-6Al-4V disks. All 24 implants were placed in 3 adult dogs. Degradation potential of bulk versus incrementally applied and indirect composites: color, microhardness, and surface deterioration. Curing efficiency was evaluated by determining the surface microhardness (VHN) of the resin specimens. Journal of Advanced Prosthodontics. This study evaluated the initial stability of different implants placed above the bone level in different types of bone. Color differences among ceramic specimens were measured using a spectrophotometer (VITA Easyshade, VITA Zahnfabrik, Bad Säckingen, Germany) and data were expressed in CIELAB system coordinates.

The impression made with the polyvinylsiloxane was first poured to prepare the die cast. The ANOVA showed that the pick-up type impression coping exhibited a significantly lower error rate than the transfer type. There was no statistical correlation between the ISQ values and PTV. Many dentists use desensitizing agents to prevent hypersensitivity. The thickness of ceramic disc increased, the VHNs of all four resin types were decreased (P<.05). The study groups were divided into a control group (no membrane) and two experimental groups (SF membrane and Bio-Gide®). Egilmez F, Ergun G, Cekic-Nagas I, Vallittu PK, Lassila LV. Tooth were prepared with 2 mm ferrule and restored with nickel-chromium crowns. The silicoated group showed the highest value in shear bond strength of Ti-6Al-4V alloy, metal conditioner treated group, sandblasted group, TiN coated group, in following order. Light-post) cementation and core foundation; in group DMO, these procedures were performed simultaneously in one step, while DMT group was accomplished in separated two steps. To compare the effect of sodium hypochlorite and microwave disinfection on the dimensional stability of denture bases without and with relining. The Journal of Prosthodontics promotes the advanced study and practice of prosthodontics, implant, esthetic, and reconstructive dentistry. Thirty-six male Sprague Dawley rats with two 5 mm-sized circular defects in the calvarial bone were prepared (n=72). The affected region resembles the normal color of oral mucosa rather than appearing as a white color since the epithelial surface is not hyperkeratinized. A 3D Finite Element Analysis of Bone Tissue in 3-Unit Implant-Supported Prostheses: Effect of Splinting Factor and Implant Length and Diameter Overall mean gap values for the three groups was found to be 155.93±33.98 µm with Anatomical Occlusal preparation design having the least gap value of 139.23±30.85 µm showing the best adaptation among the groups. As described by Lekholm and Zarb, cortical layers of bovine bone specimens were trimmed to a thickness of 2 mm, 1 mm or totally removed to reproduce bone types II, III, and IV respectively. The overall rank of Journal of Advanced Prosthodontics is 7906. All failures occurred at the resin-zirconia interface. Use of custom tray and tray adhesive is clinically recommended for elastomeric impression material. Group 1 showed the maximum and Group 5 showed the least value. A one-way analysis of variance (ANOVA) at a confidence level of 95% was used to evaluate the data and Tukey's studentized range test was used to determine significant differences between the groups. J Calif Dent Assoc 2009;37:389–398. Group 2 and 5 showed relatively larger distortion value than other groups. Chinese Journal of Prosthodontics; European Journal of Prosthodontics; European Journal of Prosthodontics and Restorative Dentistry; International Journal of Prosthodontics; Journal of Advanced Prosthodontics; Journal of Indian Prosthodontic Society Resin modified glass ionomer cement exhibited the highest retentive strength and all dentin treatments resulted in significantly different retentive values (In Kg. These occlusal errors can be corrected in two ways: i) in patient's mouth ii) by recording new centric relation and remounting dentures on an articulator.

The Journal of Prosthetic Dentistry is the leading professional journal devoted exclusively to prosthetic and restorative dentistry.The Journal is the official publication for 24 leading U.S. international prosthodontic organizations. The proportions of porosity on the fractured surface were calculated on the images acquired through the scanning electronic microscope. After firing of veneering porcelain the difference was insignificant. Related factors such as age, implant type, length, location and prosthesis type had a significant effect on the implant survival. Gajewski VE, Pfeifer CS, Fróes-Salgado NR, Boaro LC, Braga RR. It is the official journal of the American College of Prosthodontists, the American Dental Association-recognized voice of the Specialty of Prosthodontics. Adequate patient satisfaction with conventional complete dentures can be significantly increased after frenectomy. The marginal gap was smaller at the coping stage in group B (60 + 30 µm) than group A (81 + 21 µm) with statistical significance. This study compared the efficacy of SF membranes on GBR with collagen membranes (Bio-Gide®) using a rat calvarial defect model. The width and length of the maxillary central incisor were measured using Adobe Photoshop® 7.0, a software for analysis, measurement and edition of photographs. The effect of angulation on the accuracy of these 3 techniques was also evaluated. The acceptance rate of Journal of Advanced Prosthodontics is still under calculation. The Pearson correlation coefficient was used to examine the correlation between Osstell™ and Osstell™ Mentor in the first and second stages of surgery, whereas the difference between their ISQ values was evaluated using a paired t-test. Each model represented bone, implant and titanium or polyoxymethylene abutment. J Prosthodont Res 2018;62:65–74. The definition of journal acceptance rate is the percentage of all articles submitted to Journal of Advanced Prosthodontics that was accepted for publication. New bone formation was evaluated using microcomputerized tomography and histological examination. Moreover, even after thermocycling treatment, SBS of Multilink group (M2) was higher than the other groups (C2 and U2). The sputtered nanoscale Ti-Ta-Nb coatings exhibited significantly greater cell attachment compared to Ti-6Al-4V and Ti-Ta-Nb disks. Significant difference was present between mean GPA-pa SF scores obtained at T2-T3 than scores obtained at other periods for females and participants with denture-related mucosal irritation (P<.05). The disks were cast by two types of metal. This study is to investigate an appropriate drying time of tray adhesives by evaluating tensile bonding strength between two types of polyvinylsiloxane impression materials and resin tray, according to various drying time intervals of tray adhesives, and with different manufacturing company combination of impression material and tray adhesive. Retentive strength for glass ionomer cement were GLUMA (41.14 ± 2.42) > Tooth mousse (40.32 ± 3.89) > Control (39.09 ± 2.80). The distortion values of each splinting methods were measured using coordinate measuring machine, capable of recordings in the x-, y-, z-axes. Data were analyzed by two-way analysis of variance and the Tukey test. Thirty-two freshly extracted molars were transversely sectioned at the deep dentin level and bonded to air-abraded zirconium oxide ceramic disks. This study evaluated the shear bond strengths of a heat cure denture base resin to commercially pure titanium, Ti-6Al-4V alloy and a cobalt-chromium alloy using two adhesive primers. The success of titanium implants is due to osseointegration or the direct contact of the implant surface and bone without a fibrous connective tissue interface. The ISQ values were showed increased tendency after 5 weeks in every groups. To evaluate the shear bond strength of resin luting agent to dentin surfaces cleansed with different agents like pumice, ultrasonic scaler with chlorhexidine gluconate, EDTA and the influence of these cleansing methods on wetting properties of the dentin by Axisymmetric drop Shape Analysis - Contact Diameter technique (ADSA-CD). In addition, the correlations between the speech intelligibility values and acoustic variables were analyzed. SEM was done to assess the surface cleanliness. Court domicile and place of performance: Chicago, USA. To achieve a favorable level of buccal gingival margin, greater thickness of buccal supra-implant mucosa is required for the implant restorations without a neighboring natural tooth compared to the implant restorations next to a natural tooth. However, no significant difference was observed with respect to the length of the impression coping. No cohesive failure was observed in any experimental group. The distance between ala to occlusal plane lines was 29.9 mm at the tragus and 31.3 mm near the ala. This study compared and evaluated the effect of two desensitizing agents on the retention of cast crowns when cemented with various luting agents. Microwave disinfection leads to increased shrinkage of denture bases without and with relining.

In bone types III and IV, this value in the Astra implant was less than that in the other 2 implants. A-Z; Z-A; Old to Recent; Recent to Old; Publication Type. The purpose of this study was to compare men with women in terms of speech intelligibility, to investigate the validity of objective acoustic parameters related with speech intelligibility, and to try to set up the standard data for the future study in various field in prosthodontics. This study compared the bond strength of porcelain to millingable palladium-silver (Pd-Ag) alloy, with that of 3 conventionally used metal-ceramic alloys. Oper Dent 2016;41:531–540. Prosthodontics is the area of dentistry that focuses on dental prostheses. A vertical load of 11 N was applied with a frequency of 2 cycles/sec. Hampe R, Lümkemann N, Sener B, Stawarczyk B. In addition, immediate implant placement has advantages such as shortened treatment time and preservation of soft tissue architectures. The facial photographs of 40 celebrities were collected from the Internet websites. Data provided are for informational purposes only. The 1.5 mm of thickness-specimens (n = 20) were relined with 1.5 mm of autopolymerizing relining resin. 130 participants who required removable prosthesis were surveyed with a standard form that included questions regarding age, gender, education level, dental attendance, and prosthetic restoration type. Twenty men and women were served as subjects in the present study. The Zr copings were fabricated by using CAD4DENT, CAD/CAM. The copings were adjusted, cemented and were cross sectioned centrally from buccal cusp tip to lingual cusp tip into mesial and distal halves. The objective of the present study was to evaluate the effect of five different metal framework designs on the fracture resistance of the metal-ceramic restorations. Data were recorded as the mean of three colony forming unit (CFU) numerations and the borderline of the antimicrobial effect was determined at 0.1% viable cells. The specimens were placed in the Universal Testing machine (Instron, model 3366, Instron Corp, University avenue, Nowood, MA, USA) to perform the tensile test (cross head speed 5 mm/min). In this experiment, Multilink showed the highest SBS before and after thermocycling. Conventional implant protocols required a load-free healing period of three to six months between placement and functional loading of the implants. Clinical findings revealed tooth sensitivity, severe enamel erosion resembling veneer preparations, and the presence of anterior open bite. Within the limitations of this study, the pick-up type impression coping exhibited a more accurate implant master cast than the transfer type in parallel group. Fabrication of complete dentures comprises of clinical and laboratory procedures that should be executed accurately for achieving success with fabricated dentures. Significant difference was present between mean scores obtained at T0-T1 and T2-T3 than scores obtained at other periods (P<.05). 3. The poor chemical bonding of a denture base resin to cast titanium framework often introduces adhesive failure and increases microleakage. It serves both researchers and practicing clinicians by providing a forum for the presentation and discussion of evidence-based prosthodontic research, techniques, and procedures. VPS Tray Adhesive-Imprint II had a superior tensile bonding strength when compared to Silfix-Aquasil over 15 minutes. This study evaluated marginal fit of glass infiltrated alumina cores fabricated using two techniques and their marginal stability after firing cycles of veneering porcelain. GPA-pa SF scores were higher before the restoration procedure began, and decreased over time with the use of prosthesis. The statistically efficient drying time was evaluated through ANOVA and Scheffe test. (3) Primary impression made with impression plaster and secondary impression were made over with polyether impression material. Denture bases without relining showed more shrinkage when compared with relined denture bases after microwave disinfection (t = 6.09; P<.001). The purpose of this study was to determine the average facial proportions and mandibular movement capacity of 316 first-year dental students who carefully recorded them on each other. Vicker's microhardness numbers (VHNs) were measured on the bottom surfaces by a microhardness tester. Vichi A, Fonzar RF, Goracci C, Carrabba M, Ferrari M. Effect of finishing and polishing on roughness and gloss of lithium disilicate and lithium silicate zirconia reinforced glass ceramic for CAD/CAM systems. The initial stability was much affected by the implant design in bone types III, IV and the implant design such as the short pitch interval was beneficial to the initial stability of implants placed above the bone level. Access this journal on ScienceDirect. However, the correlations between the speech intelligibility scores and acoustic parameters were low. Specimens were cemented with Variolink® II resin cement. Individual crowns with loop were made from base metal alloy. J Adv Prosthodont. Received January 03, 2019; Revised April 12, 2019; Accepted April 17, 2019. EDTA was the most effective dentin cleansing agent among the compared groups. Adhesives used in this study were Silfix (Dentsply Caulk, Milford, Del, USA) and VPS Tray Adhesive (3M ESPE, Seefeld, Germany) and impression materials were Aquasil Ultra (monophase regular set, Dentsply Caulk, Milford, Del, USA) and Imprint II Garant (regular body, 3M ESPE, Seefeld, Germany). According to SCImago Journal Rank (SJR), this journal is ranked 0.61. SF membranes successfully enhanced comparable volumes of bone regeneration in calvarial bone defects compared with collagen membranes. The use of a catalyst produced a greater hardness with all polymerization methods. However, the specimens primed with the Alloy primer® (MDP monomer) showed higher bond strength than those primed with the MR bond® (MAC-10 monomer) on titanium. J Esthet Restor Dent 2016;28:56–66. An ala-tragus line and an occlusal line were drawn on the left side of the face to determine if these two lines were parallel. Desensitizing agents used were GC Tooth Mousse and GLUMA® desensitizer. Rinastiti M, Özcan M, Siswomihardjo W, Busscher HJ. Focal epithelial hyperplasia (FEH) is a human papillomavirus (HPV)-induced alteration of the oral mucosa that presents with a clinically distinct appearance. The affected oral mucosa exhibits multiple papules and nodules with each papule/nodule being flat-topped or sessile. The present study was intended to evaluate the effect of soldering techniques with infrared ray and gas torch under different gap distances (0.3 mm and 0.5 mm) on the tensile strength and surface porosity formation in Ni-Cr base metal alloy. The ala-tragus line and the occlusal plane lines were for all practical purposes parallel. There were significant differences in age, implant type and surface, length, location and prosthesis type (P<.05). The purpose of this study was to evaluate the osteoblast precursor response to titanium - 10 tantalum - 10 niobium (Ti-Ta-Nb) alloy and its sputtered coating. Within the limitations of this study, all methods of surface treatment used in this study are clinically available. The effect of artificial aging on Martens hardness and indentation modulus of different dental CAD/CAM restorative materials. It was concluded that nanoscale Ti-Ta-Nb coatings enhance cell adhesion. When veneering composite resin-metal restoration is prepared, the fact that bond strength between Ti and composite resin is relatively weak should be considered. Model 1: Implant with 3 mm titanium abutment, Model 2: Implant with 2 mm polyoxymethylene resilient material abutment, Model 3: Implant with 3 mm polyoxymethylene resilient material abutment and Model 4: Implant with 4 mm polyoxymethylene resilient material abutment. Differences in cement thickness did not influence the resin-zirconia microtensile bond strength given the same resin cement or storage conditions (P>.05). Chemical disinfection with sodium hypochlorite seems to be a safer method of disinfection with regards to physical properties such as changes in dimensional stability. ): GLUMA (49.02 ± 3.32) > Control (48.61 ± 3.54) > Tooth mousse (48.34 ± 2.94). Female participants and participants with denture-related mucosal irritation had higher GPA-pa SF scores at all time points analysed. Four implant restoration groups (first and second molars, single second molars, posterior single restorations between teeth, and anterior single restorations between teeth) were randomly chosen from one dental institute. When resin cements of adhesive monomers are applied over air-abraded zirconia restorations, the degree of fit does not influence the resin-zirconia microtensile bond strength.

These values were statistically analyzed. Contact angle measurements were performed to assess wettability of various cleansing agents using the ADSA-CD technique. Dent Mater J 2013;32:107–114. This web edition is produced by Quintessenz Verlags-GmbH, Berlin. No significant differences were found in relation to the following factors: gender, diameter and bone quality (P>.05). The denture bases without and with relining were divided into 2 groups (each n = 20). Alshali RZ, Salim NA, Satterthwaite JD, Silikas N. Long-term sorption and solubility of bulk-fill and conventional resincomposites in water and artificial saliva. After 6 months of function, silicone impressions were taken and stone models were fabricated for each restoration group. From master model, 5 impressions and 5 experimental casts, total 25 casts were made for each of 5 splinting methods. Errors occurring during the clinical and laboratory procedures of a denture may subsequently lead to the occlusal errors in the final prosthesis. Both Splinting impression copings with autopolymerizing resin following compensation of polymerization shrinkage and splinting method with impression plaster can enhance the accuracy of master cast and impression plaster can be used simple and effective splinting material for implant impression procedure. Thirty five dumbbell shaped Ni-Cr alloy specimens were prepared and assigned to 5 groups according to the soldering method and the gap distance. The Journal of Advanced Prosthodontics. The use of appropriate adhesive metal primers makes it possible not only to eliminate the need for surface preparation of the metal framework before applying the heat cure resins, but also reduce the need for retentive devices on the metal substructure. Forty extracted human molars were divided into 4 groups with 10 teeth each. Maxillary labial and buccal frena are considered as normal anatomic structures in the oral cavity. In the first stage surgery, the ISQ values of forty four implants inserted into thirty five patients were measured. Two dimensional finite element models of cylinderical implant, abutments and bone made by titanium or polyoxymethylene were simulated with the aid of Marc/Mentat software. J Esthet Restor Dent 2016;28:247–261. Venturini D, Cenci MS, Demarco FF, Camacho GB, Powers JM. Speech intelligibility test and acoustic parameters used in the present study were effective in differentiating male voice from female voice and their values might be used in the future studies related patients involved with maxillofacial prosthodontics. Clinically, with the application of resilient material abutment there is no significant change in stress distribution around implant-bone interface. This study was performed to evaluate shear bond strength (SBS) between three dual-cured resin cements and silica coated zirconia, before and after thermocycling treatment. It is one of nine dental specialties recognized by the American Dental Association (ADA), Royal College of Dentists of Canada, and Royal Australasian College of Dental Surgeons. The accuracy of the implant master cast did not differ for different lengths of impression coping of at least 11 mm. To compare the accuracy of marginal and internal adaptation of zirconia (Zr) copings fabricated on anatomic (A), semi-anatomic (SA) and non-anatomic (NA) occlusal surface preparations. Stawarczyk B, Awad D, Ilie N. Blue-Light transmittance of esthetic monolithic CAD/CAM materials with respect to their composition, thickness, and curing conditions. Also, bond strengths of all three cements decreased after thermocycling. Ceramics have a long history in fixed prosthodontics for achieving optimal esthetics and various materials have been used to improve ceramic core strength. The monthly publication features timely, original peer-reviewed articles on the newest techniques, dental materials, and research findings. Statistical analysis was performed with the use of Kaplan-Meier analysis, Chi-square test and odds ratio. Ti-Ta-Nb coatings were sputtered onto the Ti-Ta-Nb disks. J Dent 2015;43:1511–1518. The mean fracture strength was highest in group DCT followed in descending order by groups DMO, DMT, and LCT. Mechanical fatigue degradation of ceramics versus resin composites for dental restorations. Implant level impressions were made after square impression copings were splinted using 5 different techniques as follows. The a* values increased for 1 mm and 1.5 mm thicknesses (P<.01), while it decreased for 0.5 mm specimens. Thinner ceramic disc with increased curing time resulted higher VHN values of all resin materials. https://doi.org/10.4047/jap.2019.11.2.128. Measurements recorded at 9 predetermined points showed variations for the three groups. This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cementon crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. Sixty two implants were inserted into 47 patients, and their ISQ values were measured using Osstell™ and Osstell™ Mentor. However, the mean ΔE values were less than 3.7ΔE units which is rated as a match in the oral environment. In NON-MEDIA group, however, there were significant differences between female and male.
