CAD, IPS). 30 natural premolar teeth of average size were prepared (n=10 each group) by computer numerical control (CNC) to fulfill the criteria of all ceramic crown design. Optical impressions were taken for each tooth preparation using the CAD/CAM scanner. 30 crowns were milled from ceramic blocks based on the optical data. A total of 30 crowns were fabricated using CAD/CAM system, and divided into three groups (IPS e.max, VE and VS). The vertical marginal gap was measured using stereomicroscope before, after cementation and after thermo mechanical cyclic loading. Results: No statistically significant difference in vertical marginal gap within or between groups of three tested materials before, after cementation and after thermo mechanical cyclic loading. Conclusions: Vertical marginal adaptation of all tested ceramics was within the clinically acceptable values.","PeriodicalId":117944,"journal":{"name":"Al-Azhar Journal of Dental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132496076","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}

Results : Intergroup comparisons of the mean treatment changes revealed significant improvements (P ≤ .05) in SNB°, SN-Pog°, Ar-Go-Me°, Co-Gn mm, B-Sv mm, Pog-Sv mm, S-Go mm, and lower lip advancement (Li-Sv mm and Pog’-Sv mm) in MPA-IV group. While in the PS group, there were significant greater decrease of SNA° and upper incisors retraction (P ≤ .05).
