老年人修复的咬合设计策略——一些共识性的意见和一种数字化新方法OA

As the population ages,the demand for complex oral rehabilitation in elderly patients continues to grow.Challenges,such as extensive tooth loss,abnormal jaw relationships,alveolar ridge resorption,and age-related degenera-tive changes in the stomatognathic system,complicate prosthetic treatments.This article illustrates a digital workflow for personalized occlusal design and rehabili-tation on the basis of digital twin technology by using the case of a 68-year-old fully edentulous female patient with mandibular deviation and temporomandibular joint structural abnormalities.Three-dimensional jaw position adjust-ment,occlusal plane design,and occlusal contact optimization were achieved by constructing a patient-specific digital twin model,significantly improving the predictability and functional adaptation of the prosthesis.This digital approach ef-fectively reduces the number of visits and chairside time;minimizes reliance on clinical experience;and offers an effi-cient,precise,and scalable solution for complex prosthetic rehabilitation in the elderly.
