摘要

保留人工牙根周圍的角化牙齦會是最理想的，尤其是美觀關鍵區域。早在1994年Hertel等學者就發表二階段植牙系統第二次手術時的切線技法。由於他們使用的是直線切法，因此翻瓣對圓形的癒合支柱無法貼附良好。本報告的目的是提出改良式切線技法應用於二階段植牙系統第二次手術。簡言之，就是將直線切法改良成半月形的切線法，如此就可以讓翻瓣和圓形的癒合支柱完全貼附良好。對於單顆植牙或是多顆植牙都可以得到良好的結果。

The preservation of keratinized mucosa around the dental implant seems to be ideal, especially in the esthetic-critical area. The incisional technique with apically positioned falp has been reported to preserve keratinized tissue during the second surgery of two-stage implant (Hertel RC et al. 1994). The disadvantage of this straight line incision technique is difficult to make the flap margin adapt the healing abutment well due to its round shape. Therefore, the purpose of this presentation is to report a modified incisional technique for the second surgical procedure of two-stage implant. Briefly, first is to locate the site of installed implant before second surgery. Then, to make a semilunar incision on the crest area instead of straight line incision which can make a gap between the flap and the unreflected soft tissue causes the healing and esthetic problems. For single implant in the partial edentulous area, the semilunar incision with two vertical releasing incisions can create good contour for the adaptation between the healing abutment and soft tissue labially or buccally. The remaining tissue on the lingual side can either be cut away or used to help to regenerate interdental papilla. This modified incisional technique makes the management of soft tissue around dental implant much easier and better clinical results.
