The purpose of this paper is to introduce an effective technique to easily obtain adequate amounts of keratinized gingiva and vestibular depth.
Free gingiva (vertical height 10 mm) was harvested on the palatal mucosa and a partial thickness flap was elevated on the recipient site with same width as the free gingiva graft. After a conventional suture, a titanium mesh covered the graft and was fixed with miniscrews. Titanium mesh was removed 4.1±2.5 weeks after surgery. The amount of keratinized gingiva and vestibular depth was measured at the final follow-up.
Nine patients (males 4, females 5; 53.9±14.1 years) who underwent bone graft surgery before vestibuloplasty were included. No free gingival graft failure or complications were encountered in any of the patients. The relapse rate for vestibular depth (23.3%) was lower than that for keratinized gingiva (48.3%) after 34.4±14.4 months (=0.010).
Vestibuloplasty with a free gingival graft using titanium mesh could be achieved with an acceptable amount of keratinized gingiva and an appropriate vestibular depth around dental implant.
本文旨在介绍一种能轻松获取足够量角化龈和前庭深度的有效技术。
从腭黏膜获取游离龈（垂直高度10毫米），在受区掀起与游离龈移植物宽度相同的部分厚度瓣。常规缝合后，用钛网覆盖移植物并用微型螺钉固定。术后4.1±2.5周取出钛网。在最终随访时测量角化龈量和前庭深度。
纳入9例在进行前庭成形术前接受骨移植手术的患者（男性4例，女性5例；年龄53.9±14.1岁）。所有患者均未出现游离龈移植物失败或并发症。34.4±14.4个月后，前庭深度的复发率（23.3%）低于角化龈的复发率（48.3%）（P=0.010）。
使用钛网进行游离龈移植的前庭成形术可获得可接受量的角化龈以及种植体周围合适的前庭深度。
