摘要

文獻報告對於原本有牙齦退縮的牙齒在做齒顎矯正治療前是否須先做牙周手術頗有爭議，但如果是附連牙齦不足的牙齒，再做矯正時易加速牙齦退縮，因此有些學者建議矯正前應先做牙齦移植手術，本報告是一例在矯正治療前利用牙齦移植體成功地防止牙齦退縮惡化的病例。患者是一名十歲女孩，上顎有一正中贅生齒，右上中門齒與側門齒為唇舌側重疊，右上中門齒不但缺乏附連牙齦，且有牙齦退縮及發炎的現象。先以牙齦移植體增加右上中門齒附連牙齦的寬度，之後拔除正中贅生齒，一個星期後開始以2×4固定矯正治療將右上中門齒往近心端移動，並將右上側門齒往唇側移動。治療後右上中門齒沒有牙齦繼續退縮的現象發生，且牙齦健康情況良好。牙齦移植體是用來增加附連牙齦寬度效果相當好的術式，若要進行矯正治療的病人缺乏附連牙齦，又有牙齦退縮的顧慮時，建議先做牙齦移植，再接著做矯正治療，以避免不必要的牙齦退縮。

A controversy exits in the literatures as to the need for a periodontal surgery before orthodontic treatment is a gingival recession tooth. However, if keratinized gingiva is absent, the recession may progress during orthodontic treatment. For prevention of further recession, a gingival graft is indicated before tooth movement. This case report describes a patient with a mesiodens and labiolingual overlapping of right upper central and lateral incisors, in whom the absence of keratinized gingival, gingival recession and gingival inflammation of right upper central incisor were also noted. Free gingival graft was done. Then, right upper central incisor was moved to mesially and lateral one to labially by 2×4 orthodontic technique. The gingival recession did not progress and gingival remained healthy.
