冠向移位瓣合併牙釉基質衍生物與冠向移位瓣合併結締組織移植體治療上顎雙側犬齒牙齦萎縮

牙齦萎縮不但會造成美觀不佳還有可能造成牙根敏感，進而影響患者的生活品質，臨床上利用牙根覆蓋術來治療牙齦萎縮的方法很多，其中又以冠向移位瓣合併結締組織移植體這個術式，最能獲得長期牙根覆蓋的穩定與增加角化牙齦寬度，而牙釉基質衍生物能促進傷口癒合及牙周再生的作用，故冠向移位瓣合併牙釉基質衍生物這個術式，也是常被各學者們提出的治療選項。本病例系列報告，提出兩個不同病例，各以上述兩種不同術式來進行雙側牙根覆蓋術，紀錄術後1年追蹤結果並進行討論。

Gingival recession will cause not only esthetic problems but also possible root sensitivity. Thus, affecting the patient's life quality. Clinically, there are many different root coverage surgical methods treating gingival recession. Among these methods, coronally advanced flap(CAF)combined connective tissue graft(CTG)can lead to the best long-term stability of the root coverage. Also, an increase in the width of keratinized gingiva. As for enamel matrix derivative(EMD), it can promote wound healing and periodontal regeneration. Thus, coronally advanced flap combined with usages of enamel matrix derivative is also commonly discussed as an alternative by several authors. This case series will provide two case reports using different surgical methods as discussed above(CAF+CTG; CAF+EMD)to perform bilateral root coverage surgery. Results: The patient from Case 1 received root coverage surgery using CAF+EMD. The gingival recession of tooth 13.23 improved from 2.5mm to 1mm after root coverage. The patient from Case 2 received root coverage surgery using CAF+CTG. The gingival recession of tooth 13.23 was 3 mm and 3.5 mm, respectively, and post-op results were both 0 mm, achieving full coverage of the roots. Conclusion: From this case series, the amount of root coverage is predictable by either of these two methods (CAF+EMD or CAF+CTF).
