上颌交替快速扩缩结合前牵的研究进展

Progress of research on alternate rapid maxillary expansions and constrictions

上颌交替快速扩缩(alternate rapid maxillary expansions and constrictions,Alt-RAMEC)是Liou在2005年提出的一种新的扩弓方法,可以更大程度地松解上颌周围骨缝,来促进上颌前牵效果。与快速扩弓辅助前牵相比,能更有效地矫正上颌发育不足,获得更多的骨骼效果。本文综述了传统Alt-RAMEC装置特点、临床效果、长期稳定性以及对气道的影响和牙周副作用,为推广临床应用提供参考。

Alternate rapid maxillary expansions and constrictions(Alt-RAMEC) is a new method of expansion proposed by Liou in 2005,which expands sutures around maxilla more effectively and leads to greater amount of maxillary protraction.Compared with rapid maxillary expansion and facemask,it can obtain better skeletal effects and correct maxillary deficiency more efficiently.This paper reviews characteristics of the conventional Alt-RAMEC device,clinical outcomes,long-term stability,airway changes and periodontal complications in order to provide reference for promoting clinical application.
