研究目的:

我国65岁以上年龄组自述牙列缺失率高达27.8%,种植支持咬合重建被推荐为牙列缺失患者的首选治疗方式,术前设计要求高,需要颌位关系即OVD与水平颌位关系、𬌗平面及牙齿形态等信息,颌位确定是全程数字化种植支持咬合重建的唯一瓶颈,技术敏感性极高,患者体验感差,尚缺乏数字化智能定颌位关系和牙列形态的方法。 本研究目的为 (1)建立正侧面二维照片和自动配准的三维面部扫描-口内牙列扫描(牙列缺失者采集黏膜形态)-上下颌骨锥形束CT-运动轨迹多模态多中心的口腔医学数据库; (2)本项目以牙列缺失患者种植支持咬合重建的关键背景为基础,通过建立多中心数据库,运用卷积神经网络、跨模态翻译和弱监督等深度学习方法。研究不通过任何口内操作的机器可视化化方法确定牙列缺失患者颌位关系与牙列形态动态调𬌗,为种植方案设计奠定基础; (3)改进人工智能辅助全程数字化种植支持咬合重建软件的建立并完成临床验证。  

Objectives of Study:

In China, 27.8% of individuals aged 65+ self-report edentulism. Implant-supported occlusal reconstruction is the recommended primary treatment but requires precise preoperative design, including jaw relation (OVD, horizontal position), occlusal plane, and tooth morphology. Determining jaw relation remains the key bottleneck in fully digital workflows, being technically sensitive, patient-unfriendly, and lacking intelligent digital solutions. This study aims to: (1) Establish a multicenter multimodal database integrating 2D photos (frontal/lateral), auto-registered 3D facial scans, intraoral/mucosal scans, maxillomandibular CBCT, and mandibular movement trajectories. (2) Use this database with deep learning (CNNs, cross-modal translation, weak supervision) to develop a non-invasive, machine vision-based method for determining jaw relation and dynamically adjusting occlusion in edentulous patients, enabling implant planning without intraoral procedures. (3) Refine and clinically validate AI-assisted fully digital implant-supported occlusal reconstruction software.
