摘要


在增加角化附連牙齦的手術中,自體腭黏膜移植體一向被認為是可預測性最佳的一種植體材料。然而,它的一些缺點,於過去三十多年中,促使人們持續尋找一種較佳的替代品。所有活的移植體,多少都具有與腭黏膜移植體相似的缺點。至於去活性的移植體,文獻記載中,臨床結果雖然不盡相同,好些研究者認為它們充其量只不過是生物性繃帶,並沒有能力決定自身在癒合後的組織種類(例如角化或非角化)。本臨床報告介紹一種新的材料-冷凍乾燥無細胞皮膚基質同類異體移植體-作為增加角化附連牙齦手術的植體材料,同時也提出一些建議,以提高手術的可預測性。

Autogenous palatal mucosal graft (PMG) has been considered the most predictable grafting material when utilized to increase attached keratinized gingiva. However, several disadvantages have fostered investigators to search for a better alternative during the past 3 decades. All kinds of vital grafts have similar problems as what PMG has had. As for the devitalized grafts, although the clinical results were various, some researchers regarded them as a biologic bandage at best, namely, the devitalized grafts lacked the capability of dominating the specificity of the overlying epithelium. This clinical report introduces a novel material – freeze dried acellular dermal matrix allograft – to serve as a grafting material for the purpose of increasing attached keratinized gingival, and makes some advices to help in raising the predictability of the result.
