Abstract

Anterior open bite is defined as a condition in which upper incisor crowns fail to overlap the incisal third of the lower incisor crowns when the mandible is brought into full occlusion. The diagnosis, treatment, and successful retention of treated open-bite malocclusion continue to be a constant subject of discussion and study, contributing to the frustrations of clinicians. Various modalities have been used for the correction of open bite for the different age groups. In adult cases, an open bite can be corrected either by anterior extrusion or posterior intrusion, or a combination of both. Kim had described a method of using multiloop edgewise archwire for posterior intrusion. Here is a case report in which an innovative method is described which is a modification of Kim's method which is simpler, less time-consuming to place, hygienic, and they do not irritate the soft tissue. The bite closing mechanism and the treatment results are similar to Kim's method.

摘要

前牙开牙合被定义为一种在下颌完全咬合时,上颌切牙牙冠未能覆盖下颌切牙牙冠切缘三分之一的情况。前牙开牙合错牙合畸形的诊断、治疗以及治疗后成功保持一直是持续讨论和研究的主题,这给临床医生带来了困扰。针对不同年龄组,已采用多种方式来矫正开牙合。在成人病例中,开牙合可通过前牙伸长或后牙压低,或两者结合来矫正。金曾描述过一种使用多曲方丝弓矫治器进行后牙压低的方法。本文报告了一例采用创新方法的病例,该方法是对金氏方法的改良,更简单、放置耗时更少、卫生且不会刺激软组织。咬合关闭机制及治疗效果与金氏方法相似。
