摘要

种植体周围的粘膜龈畸形是临床实践中经常发现的问题,通常表现为角质化组织不足和粘膜厚度不够。表型修正疗法可以增加种植体周围粘膜厚度和角质化粘膜的数量,从而改善种植体的长期临床效果。游离龈移植(FGG)被认为是增加角化粘膜的黄金标准;但是,由于技术敏感性,种植体舌侧的游离龈移植预测性较差,而且由于血液供应有限,经常出现组织厚度增加不足的情况。带有骨膜下隧道结缔组织移植(CTG)的半月状舌侧上位皮瓣(SLAP)可以增加种植体周围粘膜厚度和角化粘膜的周缘宽度。SLAP包括在颊侧角质化粘膜内的一个全厚半月形切口,以及种植体中远端两个垂直释放切口,从舌侧延伸到牙槽粘膜。在种植体舌侧将组织顶端定位,并缝合到位,通过颊骨膜下隧道为 CTG 创造颊空间。SLAP 是一种微创且可预测的改善种植体周围粘膜表型的方法。本病例报告显示,在使用 SLAP 和上皮下 CTG 的 10 个月期间,种植体周围粘膜厚度和角化粘膜的数量均有增加。

Semilunar Lingualized Apically Positioned Flap (SLAP) for Peri-implant Soft Tissue Phenotype Modification Therapy Around Mandibular Implants: A Case Report.

Mucogingival deformities around implants are frequent findings in clinical practice and often pre- sent as inadequate keratinized tissue and insufficient mucosal thickness. Phenotype modification therapy can increase peri-implant mucosal thickness and the amount of keratinized mucosa, im- proving the long-term clinical outcomes of implants. The free gingival graft (FGG) is considered the gold standard to increase keratinized mucosa; however, FGGs on the lingual aspects of implants are less predictable due to technique sensitivity and often present with insufficient gains in tissue thick- ness due to a limited blood supply. The semilunar lingualized apically positioned flap (SLAP) with subperiosteal tunnel connective tissue graft (CTG) can increase both peri-implant mucosal thick- ness and keratinized mucosal width circumferentially. SLAP consists of one full-thickness, semi- lunar incision within the keratinized mucosa and buccal to the implant, as well as two vertical re- leasing incisions mesial and distal to the implant, extending lingually into the alveolar mucosa. The tissue is apically positioned lingual to the implant and sutured in place, creating buccal space for a CTG via buccal subperiosteal tunneling. SLAP is a minimally invasive and predictable approach for improving the peri-implant mucosal phenotype. This case report demonstrates gains in peri-implant mucosal thickness and the amount of keratinized mucosa over a 10-month period utilizing SLAP with subepithelial CTG.

期刊介绍: The International Journal of Periodontics & Restorative Dentistry will publish manuscripts concerned with all aspects of clinical periodontology, restorative dentistry, and implantology. This includes pertinent research as well as clinical methodology (their interdependence and relationship should be addressed where applicable); proceedings of relevant symposia or conferences; and quality review papers. Original manuscripts are considered for publication on the condition that they have not been published or submitted for publication elsewhere.
