Partial edentulism and
Conditions
Interventions
Immediate anterior teeth group (Study 1):More than one temporary resin restorations and one formal all ceramic restorations using either classic or fully digital processes are fabricated for each pati
Test group of edentulous jaw (Study 2):Import the preoperative CBCT of the patient into IVSP Image software, and design the implant on the computer according to the newly proposed optimization method
Control group of edentulous jaw (Study 2):Experienced physicians conduct preoperative design based on their own experience and relevant principles. After the design is completed, the optimization plan
