After surface roughness measurements and SEM analysis, the specimens were subjected to thermomechanical aging. Pre- and post-aging scans were analyzed to calculate wear depth. Surface roughness and SEM analyses were repeated, and 2-way ANOVA with Tukey's HSD test was used for statistical analysis.Results: Glazed surfaces exhibited significantly higher wear depth than polished ones (p = .018). Vita Enamic showed significantly greater wear depth compared to both VarseoSmile Crown Plus (p = 0.002) and P-Crown V2 (p = 0.001). For polished surfaces, Vita Enamic had significantly greater wear depth than VarseoSmile Crown. Plus (p = 0.001) and P-Crown V2 (p < .05). Initially, surface roughness values for glazed surfaces were similar (p = .076), but aging increased roughness significantly, with glazed P Crown V2 being rougher than glazed VarseoSmile Crown Plus (p = .001). After aging, glazed surfaces had significantly higher surface roughness than polished ones across all materials.Conclusion: Material type and surface treatment affected surface roughness and wear depth during thermomechanical aging. Glazed surfaces showed higher wear depth and roughness, with the glaze layer removed after aging. Polished surfaces exhibited greater wear for subtractive materials.","PeriodicalId":94232,"journal":{"name":"The International journal of prosthodontics","volume":"0 0","pages":"1-21"},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143702628","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}

X-ray diffraction, scanning electron microscopy, and ONH analysis were used to evaluate the casting ingot, powders, and frameworks' phase compositions, grain size, and microstructure. Three-point bend tests were used to assess the metal-ceramic bond strengths. Metal-ceramic bond strength values were compared using a one-way analysis of variance.Results: The bond strengths did not show significant differences (P>.05) between Groups C (29.95 ±4.60), V (31.32 ±3.44), and R (29.90 ±5.50). The recycled alloy powder's grain size (14.1 ±6.33 µm) was more significant than that of the virgin alloy powder (12.24 ±6.03 µm). Twenty-five times reused alloy powder had a greater N concentration than virgin powder. Group V and R had similar X-ray diffraction patterns, but the Group R frameworks had porous microstructure.Conclusion: Reusing cobalt-chromium alloy powder 25 times did not affect the metal-ceramic bond strength. Recycling the cobalt-chromium alloy powder is advisable.","PeriodicalId":94232,"journal":{"name":"The International journal of prosthodontics","volume":"0 0","pages":"1-23"},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143702626","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}

In total, 15 dies and one hollowed cast per taper were additively manufactured from two resins (G PRINT 3D Model [GP] and DentaMODEL [DM]). Dies and casts were digitized to evaluate their trueness (root mean square [RMS]). The fit of the dies was evaluated with crown portion's RMS when seated in the cast and with distance deviations.

Straight dies had the highest overall, root, and base RMS within GP (P ≤ .030). The 10-degree dies had the lowest overall and base RMS, lower crown RMS than straight dies, and lower root RMS than 5-degree dies within DM (P ≤ .047).

Another objective was to determine and evaluate the correlation of CIEDE2000 values analyzed using X-Rite Color i5 spectrophotometer, VITA EasyShade Advance 4.0, and Adobe Photoshop.Materials and methods: Tile specimens (n = 36) with 8 × 10 × 1.5 mm dimensions were prepared using lithium-disilicate monochromatic ingots (IPS e.max Press MT, Ivoclar) and lithium-disilicate multichromatic ingots (IPS e.max Multi Press, Ivoclar).
