切牙管影响上中切牙三维移动的研究进展
Progress in research into the influence of the incisive canal on the three-dimensional movement of maxillary cen-tral incisors
摘要
Abstract
The position of the maxillary central incisor is essential in facial aesthetics.In orthodontic treatment,the maxillary central incisor moves in three-dimensional directions according to actual situations although the range of its movement is usually assumed to be restricted by the labial and palatal cortices.An incisive canal with an irregular anato-mical shape in the maxilla can be detected through cone beam computed tomograph(CBCT),and the wall of this canal is surrounded by dense cortical bones.If the maxillary central incisor invades it,the root will be absorbed.Therefore,the range of movement is closely related to the shape and position of the incisive canal and should be considered for the pre-vention of unnecessary injury to the tooth root.This article reviews the effect of the incisive canal on the three-dimen-sional movement of the maxillary central incisor.关键词
