Two-way ANOVA with repeated measures and Sidak post-hoc test were used to compare ISQ, VBL, and HBL over time and between faces.Results: The linearity and association between ISQ, VBL, and HBL were analyzed by Spearman correlation and linear regression tests. ISQ, VBL, and HBL did not differ significantly over time (P ≥ .05). The comparison between the faces showed that only VBL presented significant differences (P ≤ .05) at 1 and 3 years between the following faces: distal and mesial, lingual and mesial, and mesial and buccal. A positive, moderate correlation was observed between ISQ and HBL of the lingual (r = 0.502; P < .01) and mesial (r = 0.536; P < .01) faces at 1 year. The VBL of the mesial face, the HBL of the mesial and lingual faces, and the overall HBL at 1 year were associated with the ISQ values obtained on these faces.Conclusions: VBL and HBL remained stable across all implant faces over the 3-year follow-up period. Nevertheless, the lingual face demonstrated the greatest VBL, whereas the mesial face exhibited the highest stability, with minimal VBL observed in the third year. Early bone remodeling, particularly during the first year of MO use, may affect implant stability and appears to be associated with HBL changes on the lingual and mesial faces.","PeriodicalId":94232,"journal":{"name":"The International journal of prosthodontics","volume":"0 0","pages":"119-126"},"PeriodicalIF":1.8,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144860038","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}

This study evaluated (a) the discrepancies of digitized impression scans captured by intraoral (IOS-IMP) and desktop scanners (LAB-IMP) compared to digitized stone cast (LS-MOD), and (b) the discrepancy of the various anatomical landmarks (peripheral, ridge, postdam, and palatal vault) between the two methods.Materials and methods: A total of 20 conventional bordermolded impressions of maxillary edentulous ridges were digitized using intraoral and desktop scanners. The impressions were poured and casts digitized using a desktop scanner. The root mean square (RMS) difference was determined by superimposing the intraoral scan and the desktop scan onto the digitized master cast. Additionally, results of different landmarks were analyzed.Results: Paired t tests, Wilcoxon tests, Kruskal- Wallis tests, and post hoc tests were used. The mean RMS for overall LS-IMP (38.90 ± 7.67 μm) was significantly different compared to the overall IOS-IMP (75.11 ± 22.37 μm; P < .01). Within the desktop scanner group, deviations between peripheral and both palatal vault and postdam were significantly different.Conclusions: Within the limitations of this in vitro study, significant differences were found between the various landmark areas when using a desktop scanner to digitize a master cast.

The aim was to minimize the number of clinical appointments while achieving functional, esthetic, and durable results.Materials and methods: An 84-yearold edentulous patient, previously discouraged by a conventional denture protocol, underwent rehabilitation using a three-appointment hybrid workflow. Digital intraoral and facial scans were captured during the initial visit using custom devices to determine the vertical dimension of occlusion (VDO) and centric relation (CR). In the second session, secondary impressions were taken with polyether materials using digitally fabricated occlusion bases. Maxillomandibular relationships were refined with the Gnathometer system, and all records were digitized. Final dentures were virtually designed and milled from polymethyl methacrylate discs, integrating the base and teeth into a monolithic structure (Ivotion, Ivoclar). The third session focused on prosthesis delivery and functional validation.Results: The hybrid protocol enabled the precise capture of anatomical and functional data while significantly reducing treatment time. The final prostheses demonstrated excellent fit, retention, stability, and occlusion, with no need for adjustments. The patient expressed high satisfaction with both the comfort and efficiency of the process.Conclusions: This case suggests that a hybrid digital protocol may offer a viable alternative for the prosthetic rehabilitation of edentulous elderly patients, particularly when reducing chair time is critical.

In sandblasted groups, dentin was air-abraded with 50-μm aluminum oxide for 10 seconds. Composite cylinders (3 × 3 mm; 7.065 mm2) were bonded using Single Bond 2, Palfique Bond, or Single Bond Universal. Shear bond strength (SBS, MPa) and failure modes were recorded, and bonding interfaces were examined by scanning electron microscopy (SEM). Data were analyzed using three-way ANOVA with Tukey HSD, Kruskal-Wallis with Bonferroni correction, and Weibull analysis.Results: Flowable composites, sandblasting, and the two-step application of Single Bond Universal each significantly improved bond strength. A three-way interaction was observed (F = 5.12, P = .01). Groups 1, 8, and 13 showed the highest bond strengths (11.47 ± 6.44, 15.88 ± 5.39, and 12.90 ± 4.98 MPa; P < .05), with Groups 8 and 13 demonstrating superior Weibull modulus (m) and characteristic strength (σο). SEM analysis revealed that these groups exhibited the most intimate adhesive-dentin contact with minimal interfacial defects. Failure mode assessment showed predominantly cohesive and mixed failures in Groups 1, 8, and 13.Conclusions: Sandblasting, flowable composites, and two-step Single Bond Universal enhance dentin bond strength. The most effective combinations were sandblasted dentin with flowable composite and Single Bond Universal (one-step), and non-sandblasted dentin with packable composite and Single Bond Universal (two-step).","PeriodicalId":94232,"journal":{"name":"The International journal of prosthodontics","volume":"0 0","pages":"31-41"},"PeriodicalIF":1.8,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145992510","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 primary outcome was esthetic appearance, assessed by the accuracy of the pink-white resin transition and an esthetic score. Secondary outcomes included oral health-related quality of life (OHRQoL), denture satisfaction index (DSI), masticatory performance (MP), maximum bite force (MBF), bite pressure (BiP), and prosthetic maintenance. Data analysis included descriptive statistics and multivariate comparison tests. The sample size was limited to 10 participants.Results: Three women and seven men (mean age: 65 years) participated in the study; nine completed the 3-month follow-up. Among the 20 prostheses, 8 presented imperfections of the white-pink transition (median: 1 mm; range: 0.3 to 10 mm). From 2 weeks onward, the novel dentures scored higher on the esthetic score than the previous dentures, which were considered ideal/ near-ideal (P < .05). A nonsignificant improvement in OHRQoL, DSI, and MP was noted, whereas MBF and BP improved significantly over the observation period (P < .05). Prosthodontic maintenance events included two small adjustments before the 2-week follow-up.Conclusions: The positive evaluations on esthetics with no or minor deviations in the transition from white to pink confirm the suitability of the design of the two-colored shell-geometry resin disk for CAD/CAM complete denture manufacturing.

The digital method allows denture teeth, denture bases, and resilient liners to be designed as components and exported as separate files for additive manufacturing. It involves importing a cast into CAD software to create a T-shaped key, designing a 2-mm resilient liner with six positioning points, generating a mandibular denture base and alignment jig, 3D printing all components, post-processing, assembling with photopolymer, and final trimming and polishing. The additional cast and alignment jig design demonstrates ensured ease of component assembly and stable occlusion. The development of this novel technique using additive manufacturing advances the applications of the digital workflow in removable prosthodontics. The method is proposed as a potential solution to the problems associated with the traditional relining process, with a particular emphasis on its compatibility with additive manufacturing processes that use diverse methacrylate formulations, in contrast to conventional polymethyl methacrylates (PMMAs).","PeriodicalId":94232,"journal":{"name":"The International journal of prosthodontics","volume":"0 0","pages":"77-83"},"PeriodicalIF":1.8,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145575110","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}
