无牙颌患者种植治疗修复空间与修复方式的选择策略OA

The restoration space should be fully considered in designing the implant restoration for edentulous patients to accommodate the superstructure of implant dentures and prostheses and select the appropriate restoration method.How-ever,no unified standard exists for the evaluation of restoration space in clinical practice.Mechanical or biological com-plications of implant dentures occur when the restorative space in the mouth does not match the prosthesis design.This study recommends recording the correct jaw relation retained by natural teeth or old dentures before implant treatment in edentulous patients.The complete digital information of the patient's oral and maxillofacial region can be obtained using digital technology,and a three-dimensional virtual dental patient model can be constructed.A functional and aesthetically oriented implant restoration plan can be designed according to the measured vertical restoration space and horizontal rela-tionship.
