[Application and development of alveoloplasty in implant-supported full-arch fixed prosthesis]

Implant-supported full-arch fixed prosthesis is hot in edentulous therapy currently. Appropriate contour of bone is the premise of good restoration outcome. Alveoloplasty is an important part during treatment procedure. Alveoloplasty can be used to obtain bone platform for implant insertion, create adequate prosthetic space, achieve good esthetic effect, and form appropriate soft tissue morphology. The design of alveoloplasty has evolved from traditional plaster models and cone beam CT to three-dimensional (3D) virtual patients. The surgical techniques of alveoloplasty have also undergone the evolution from free-hand to static guide or dynamic navigation. This article elaborates on the concept, purpose and significance of alveloplasty in implant supported full-arch fixed restoration, technology evolution and process to provide reference for clinical practice.
