Study on three-dimensional correlation between maxilla and mandible in adults
摘要
Abstract
Objective To study the three-dimensional correlation between maxilla and mandible in adults.Methods A retrospective analysis was conducted on clinical and imaging data from 105 adult patients treated at Tongliao People's Hospital between January 2010 and December 2018.Spiral CT scans were acquired and converted to DICOM format,and lateral cranial views were generated using Dolphin 11.95 software.Patients were classified into three groups based on ANB(angle formed by the maxillary alveolar ridge,nasal root,and mandibular alveolar ridge):Group Ⅰ(0°≤ ANB＜5°)(54 cases),Group Ⅱ(ANB≥ 5°)(30 cases),and Group Ⅲ(ANB＜0°)(21 cases).Three-dimensional reconstruction of the maxilla and mandible was performed using Mimics Research 21.0 software to measure volume,surface area,length,width,and height among groups.Compare the differences in measured parameters among the groups and analyze their correlations.Results Significant differences existed in surface area,length,and height of mandibles(all P＜0.05).Fur-ther inter-group comparisons revealed that Group Ⅱ mandibles exhibited significantly smaller surface areas and heights compared to Groups Ⅰ and Ⅲ,while Group Ⅲ mandibles demonstrated markedly longer lengths than Groups Ⅰ and Ⅱ,with all differences being statistically significant(all P＜0.05).In Group Ⅰ,mandibles showed correlations with maxillas in volume,surface area,and length(r values being 0.583,0.273 and 0.476,respectively,all P＜0.05).In Group Ⅱ,there was correlation in volume and surface area(r values being 0.556 and 0.444,both P＜0.05),and the same was with Group Ⅲ(r values being 0.712 and 0.649,both P＜0.05).Conclusion The volume and surface area of the maxilla and mandible are correlated,but the length,width and height in three dimensions are not significantly correlated.关键词
