Attached gingiva is a crucial aspect of healthy peri-implant tissue. Severely atrophied jaws have minimal quantities of attached gingiva. Any surgical procedure bears the potential risk of further loss of attached gingiva. The split-thickness flap described here provides excellent access. Using a biopsy punch, the periosteum is easily cut in semicircular fashion on the labial surface of the bone so that it remains pedicled on the lingual or palatal ridge. The split-thickness flap permits fixation of the gingival flap to the periosteum. The periosteal flap is closed with sutures to achieve soft tissue closure over the implants even in case of simultaneous vestibuloplasty.
附着龈是健康种植体周围组织的一个关键方面。严重萎缩的颌骨附着龈的数量很少。任何手术都有进一步丧失附着龈的潜在风险。这里描述的切开式翻瓣术提供了极好的入路。使用活检打孔器，很容易在骨的唇侧表面以半圆形方式切开骨膜，使其在舌侧或腭侧嵴上保持蒂状。切开式翻瓣术允许将牙龈瓣固定到骨膜上。用缝线关闭骨膜瓣，以实现即使在同时进行前庭成形术的情况下，种植体上的软组织闭合。
