骨支抗前方牵引矫治生长发育期骨性Ⅲ类错(牙合)畸形的研究进展OA

The facemask is the common appliance for the treatment of skeletal class Ⅲ patients with maxillary retru-sion.Bone-anchored maxillary protraction(BAMP)appliances have recently been used to overcome the limitations of tooth-borne appliances in the interceptive treatment of class Ⅲ malocclusions.BAMP has demonstrated promising initial results,attributed to its potential to offer great skeletal changes with less unwanted displacement of dentition during the late mixed dentition and early permanent dentition stages.BAMP therapy techniques significantly improve the soft tissue profile,which leads to an improvement of the concave profile.Moreover,BAMP protocol with class Ⅲ elastics has shown certain advantages in controlling vertical skeletal pattern.This work aims to review the research progress in the se-lection of BAMP protocol,necessity of combining transverse arch expansion,optimal treatment timing,and long-term treatment outcomes and explore its future development.
