摘要

牙齒喪失必定導致齒槽嵴吸收，甚至角化黏膜減少，前庭變淺。當欲以人工牙根進行贋復，常面臨植體周圍角化黏膜不足的現象。雖然角化黏膜寬度對於植體周圍組織的健康與否，仍有爭議，然而有足夠角化黏膜可減少牙菌斑堆積，減少黏膜發炎，有利於維持植體周圍組織的穩定健康。自體游離牙齦移植一直是增加角化黏膜的黃金標準，然而自體游離牙齦移植必須面對術中，術後流血與患者術區不適等問題。本篇報告三例於植牙區使用異種膠原蛋白基質獲得角化黏膜的方式，以期避免自體游離牙齦移植所可能造成的問題。

Tooth extraction may lead to significant dimensional changes in the alveolar ridge, a reduction in the keratinized mucosa and a loss of vestibular depth. When it is decided to insert an implantsupported prosthesis, any insufficiency in peri-implant keratinized tissue becomes an issue. Although the relationship between the keratinized mucosa width and peri-implant health remains controversial, having sufficient keratinized mucosa is likely to help to maintain peri-implant tissue health by reducing plaque accumulation and mucosal inflammation. Currently, free gingival grafting (FGG) is the gold standard for increasing keratinized tissue. However, bleeding during and after surgery, and discomfort at the surgical sites, etc., have become a major concern. In this article, we present three cases where keratinized mucosa was increased by the use of xenogenic collagen matrix in order to reduce patient morbidity.
