Excess tissue often exists distal to the upper second molar, creating a pocket in the maxillary tuberosity. When removed from this location, this tissue can serve as an optimal piece of connective tissue (CT), helping to both prevent periodontal disease and treat periodontal recession while also aiding in restorative dentistry. This tissue is an ideal CT for root coverage and soft-tissue ridge-augmentation grafting. This article provides an overview of CT grafting, including a discussion of tuberosity CT and its advantages versus palatal CT. The authors describe two techniques for harvesting tuberosity tissue for CT grafts, the distal gingivectomy technique and the distal wedge technique, and show examples of various uses of tuberosity tissue for CT grafts.
多余的组织通常存在于上颌第二磨牙远中，在上颌结节处形成一个袋状结构。当从这个位置移除时，这种组织可以作为一块理想的结缔组织，有助于预防牙周疾病和治疗牙周退缩，同时也有助于修复牙科。这种组织是用于牙根覆盖和软组织嵴增量移植的理想结缔组织。本文概述了结缔组织移植，包括对上颌结节结缔组织及其与腭部结缔组织相比优势的讨论。作者描述了两种用于获取上颌结节组织进行结缔组织移植的技术，即远中牙龈切除术技术和远中楔形技术，并展示了上颌结节组织用于结缔组织移植的各种用途实例。
