摘要

Utilizing soft tissue augmentation to gain keratinized tissue around natural teeth and dental implants has long been a hot issue among clinicians. Although it still remains controversial, a certain amount of keratinized tissue has been considered necessary to maintain periodontal / peri-implant health and to prevent further gingival recession. In this article, we observe the use of connective tissue graft to gain keratinized tissue around natural teeth and dental implants in two clinical cases. After twelve-month follow-up, both cases showed significant gain of the keratinized tissue with connective tissue graft. In comparison to free gingiva graft, the preliminary data showed that this approach may provide better harmony and esthetic outcomes.

現今自然牙以及人工植體周圍角質化組織重要性倍受重視，儘管對於角質化組織的有無以及其適當寬度未有明確定論，足夠角質化牙周組織寬度仍被認為對於自然牙和植體周邊組織健康維持及避免後續牙齦退縮扮演重要之角色。臨床上角質化組織增寬治療方式亦有多種選擇，因此本文針對臨床上使用結締組織移植物增加自然牙及植牙周圍角質化組織各提出一個病例先期報告，結果顯示術後超過12個月追蹤，使用結締組織移植物能夠有效增加角質化組織寬度，此外與游離牙齦移植物相比，此方式似乎更有潛力達成和諧美觀之軟組織型態。
