Physiologic Anchorage Control （生理性支抗控制）

At last orthodontists find the strongest anchorage---implant anchorage to change patient’s face! However, with the wide application of CBCT technology, we see more and more incisor roots moving out of alveolar bone. Then our specialty faces the question how to balance the facial esthetics and periodontal health. This lecture based on a CBCT study on 14 cadaver heads and several other cephlometric studies on 4 bicuspids extraction cases will discuss the limitation of teeth movements. The lecturer advises a physiologic anchorage control philosophy.

Learning Objectives

• Learning diagnostic value of CBCT on alveolar dehiscence and fenestration
• Understanding the limitation of teeth movement
• Learning a new solution to save anchorage
