Correction of Angle Class II Malocclusion and Buccal Crossbite Assisted by TADs – A Case Report

完全頰側錯咬的發生率不高，而無論以單純齒列矯正治療或配合正顎手術方式治療，皆為臨床上很有挑戰性的病例。本篇文章為一安格氏二級咬合關係合併右側小臼齒區完全頰側錯咬之病例報告。治療方法為拔除雙側上顎第一小臼齒及下顎第二小臼齒，並使用上顎頰側及側的迷你骨釘及顎間橡皮筋改正頰側錯咬、排列不整齊及暴牙的問題。本篇文章將探討利用迷你骨釘及顎間橡皮筋改正頰側錯咬的治療方式。

Complete buccal crossbite is rare and difficult to be treated either orthodontically or surgically. This article presents an adult patient with bilateral Class II molar relationship and complete buccal crossbite at the right premolars region. She was treated with four bicuspids extraction along with upper buccal and palatal TADs as well as cross elastics in order to achieve well-aligned dentition. The buccal crossbite was corrected and and good profile was achieved.
