Facial CT datasets from 40 patients were collected. Original 1 mm slices were reformatted to 3 mm, and then an AI algorithm reconstructed the 3 mm slices and converted them back to 1 mm to generate lateral cephalometric images. Three observers traced the craniofacial landmarks manually and with autotracing. Landmark discrepancies were quantified between the original 1 mm CT slice and the AI-reformatted 1 mm CT slice, as well as between the original 1 mm CT slice and the 3 mm CT slice. Landmark discrepancies were then compared and reliability tests conducted. AI-reconstructed 1 mm CT images showed significantly fewer discrepancies than the 3 mm CT images, particularly in critical landmarks such as the sella, basion, nasion, orbitale, and pogonion (<em>p</em> &lt; 0.05). The greatest discrepancies in the 3 mm images were observed in the sella and basion. Interobserver and intraobserver reliability analyses showed high consistency (Cronbach's <em>α</em> &gt; 0.7 in nearly all cases). These results support the use of AI-reconstructed images for more accurate diagnosis and treatment planning in craniofacial surgery, potentially reducing the need for additional imaging.</div></div>","PeriodicalId":54851,"journal":{"name":"Journal of Cranio-Maxillofacial Surgery","volume":"53 3","pages":"Pages 214-221"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142808553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pearson's chi-squared test and ANOVA were used to analyze the differences in smile characteristics across the preoperative groups.
