生长发育期骨性Ⅲ类错畸形骨支抗上颌前牵引的研究进展

Research progress on maxillary protraction with skeletal anchorage in growing patients with Class Ⅲ malocclusion

骨性Ⅲ类错畸形是临床上常见的一类多因素错畸形。对于生长发育期以上颌发育不足为主的骨性Ⅲ类错畸形,临床上较常采用的矫形治疗方法是上颌前牵引。随着骨支抗在正畸临床中的广泛应用,骨支抗上颌前牵引在骨性Ⅲ类错畸形的矫治中展现出良好的应用前景。相较于牙支抗上颌前牵引,骨支抗上颌前牵引所产生的骨性效应显著,可减少甚至消除不利的牙性效应。本文就近年来的相关研究进展作一综述,以期为临床实践提供参考。

Skeletal ClassⅢmalocclusion,which has many multiple factors,is a common type of malocclusion in clinics.Maxillary protraction,an orthopedic therapeutic method,has commonly been used to treat skeletal ClassⅢmalocclusion with maxillary deficiency in growing patients.With the extensive application of skeletal anchorage in orthodontic clinical work,maxillary protraction with skeletal anchorage has a good application prospect in the treatment of skeletal ClassⅢmalocclusion.In comparison with dental anchored maxillary protraction,maxillary protraction with skeletal anchorage produces more bone defects and can significantly reduce or even eliminate adverse dental effects.This study reviews the research progress on maxillary protraction therapy with skeletal anchorage for skeletal ClassⅢmalocclusion to provide a reference for clinical practice.
