An auto-polymerized denture repair material (PER) or a light-polymerized (MRB) denture relining material was polymerized on the disks. All specimens were stored in distilled water at 37 °C for 24 h. Half of the specimens underwent thermocycling (5,000 cycles, 5-55 °C; TC). SBS testing was conducted (n=20 per group), and the fracture pattern was analyzed. The SBS data were analyzed using non-parametric Kruskal-Wallis tests and Weibull distributions with the maximum likelihood estimation.Results: MRB specimens showed significantly higher SBS and Weibull characteristic strength values than PER specimens (P < .001), irrespective of the denture base material. No statistical differences were observed in Weibull modulus among the specimens, except PMMA-MRB specimens, which showed the highest values (P < .001). Thermal aging tended to decrease these values; however, no significant differences were observed between the non-TC and TC groups. Adhesive failure was dominantly observed in the specimens, except DLP-MRB specimens, which shifted to cohesive failures within the denture base.Conclusions: The repairability of the DLP specimens was comparable to those of the PMMA specimens. Thus, the denture repair of the DLP denture base could be treated in the same manner as conventional PMMA denture base.","PeriodicalId":94232,"journal":{"name":"The International journal of prosthodontics","volume":"0 0","pages":"1-24"},"PeriodicalIF":0.0,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144692914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this in-vitro study was to compare the mechanical properties of interim restorative materials produced using stereolithography (SLA), digital light processing (DLP), and liquid crystal display (LCD) technologies with the specimens produced by milling and conventionally manufactured polymethylmethacrylate (PMMA).Materials and methods: Six different 3D-printers [2 brands for each of SLA (Formlabs and DWS), DLP (Asiga and Mega), and LCD (Vega and Photon) technologies] were used as experimental groups, and milling (Tempo-Cad; Ondent) and conventional (autopolymerizing PMMA, Imident; Imicryl) methods were used as controls. According to International Standards Organization (ISO) 10477:2004, 120 rectangular prism interim resin specimens with dimensions of 25×2×2 mm were prepared. The manufactured specimens were subjected to 3-point bending and micro-hardness tests. A Weibull analysis was performed. Fracture surface analysis was performed using SEM (FEI Quanta 650). Statistical data analysis was performed with a one-way ANOVA and a post hoc Dunnett T3 test (α =.05).Results: The mean flexural strength value of the milling group was statistically significantly higher than all other groups (P<.05) except the Formlabs group (P = 1.000). The mean elastic modulus values of DWS, Formlabs, Asiga, Vega, and conventional groups were not statistically significantly different from the milling group. All 3D-printer groups, except Photon, showed a statistically significantly higher microhardness value than the conventional group.Conclusion: All the interim resin materials produced with 6 different 3D-printers constituted a good alternative to the conventional method. However, only resin material produced with Formlabs showed similar mechanical properties to the milling method.","PeriodicalId":94232,"journal":{"name":"The International journal of prosthodontics","volume":"0 0","pages":"1-27"},"PeriodicalIF":1.8,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144692908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impression for the DCD was done using indirect scanning of the cast. When the patients were pain free, each set of dentures was worn for 4 weeks. The Oral Health Impact Profile (OHIP-14) and the Denture Satisfaction Index (DSI) were used to measure patient satisfaction and chewing ability, respectively. Both questionnaires were administered before fabrication and after wearing each set. Adjustments made during the follow-up period were included. At the end of the study, patients could express which set of dentures they preferred. The 25 dental students involved in fabricating the dentures were questioned in terms of discomfort, preference, and future use for both techniques.Results: OHIP-14 showed significantly higher scores for DCDs for the domain concerning psychologic discomfort. The DSI showed no significant difference for both sets of dentures. In terms of complications, a significant difference was found for occlusion. DCDs required more occlusal adjustments. A minority of the patients (37.5%) chose DCDs as their favorite set.

The technique was tested to compare the behavior of three resin base materials for dentures.Materials and methods: Bar-shaped samples of the polymethyl methacrylate (PMMA)-based resin Probase Hot (Probase), CAD/CAM disk Ivobase CAD (IvoCAD), and high-impact resin IvoCAP were aged in artificial saliva for 15, 30, 45, 60, 90, 120, and 180 days at 55°C, 75°C, and 90°C. Flexural strength and surface roughness of the three resins for each aging duration and temperature were measured for three samples (n = 189). Using the time-temperature equivalence principle and the Arrhenius model, a master curve was constructed, the activation energy of the simulated aging process was calculated, and the lifetime of each material was estimated based on degradation of flexural strength value over time.Results: The mean initial flexural strength was 87.98 ± 7.37, 79.35 ± 10.01, and 97.31 ± 4.97 MPa for IvoCAD, IvoCAP, and Probase, respectively. Activation energies of the aging in artificial saliva were measured at 81.9, 82.6, and 66.2 kJ/mol, respectively, and average lifetimes at 37°C were estimated at 19.5, 14.4, and 9.2 years.Conclusions: In this first approach to estimating the in vitro lifetime in artificial saliva of resin-based materials for dentures, the three materials met the expected criteria, validating the estimation method. Therefore, thermally accelerated aging and the Arrhenius model could be an interesting tool to add to routine tests used to validate new polymer materials and manufacturing processes.","PeriodicalId":94232,"journal":{"name":"The International journal of prosthodontics","volume":"0 0","pages":"409-417"},"PeriodicalIF":0.0,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142866877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comprehensive literature search was conducted in PubMed, Scopus, and ISI Web of Science until May 2024. Keywords based on the PICO question were used without time or language restrictions. In vitro studies assessing full-arch implant rehabilitations that compared photogrammetry with intraoral scanning were included. The risk of bias was assessed using the Quin Tool Method. Data were analyzed through meta- analysis in RevMan (Review Manager Cochrane), grouping the results into three subgroups: angle deviation (°), precision (μm), and trueness (μm). The search yielded 6348 studies; 11 met the eligibility criteria, and 7 provided sufficient data for quantitative meta-analysis. Photogrammetry demonstrated superior precision, with a mean difference (MD) of -0.03 (95% CI: -0.04, -0.02) and a high weight of 94.2%, indicating consistent evidence. For angle deviation (MD = -0.12, 95% CI: -0.16, -0.08, P < 0.00001) and trueness (MD = -0.16, 95% CI: -0.19, -0.13, P < 0.00001), the photogrammetry group also showed favorable results. Although trueness exhibited expressive mean difference values, it had a lower overall weight (5.8%). Within the limitations of this study, photogrammetry significantly improves the accuracy of full arch implant rehabilitations compared to intraoral scanning.
