Root coverage can be achieved by many techniques. In this case report a patient was treated with a connective tissue with partial thickness double pedicle graft, which resulted in complete root coverage. However, 6 days postsurgery the patient developed a bleeding problem from the palatal donor area. For this reason, a unique approach was used to treat the next area needing root coverage. The procedure combined an acellular dermal matrix and a coronally positioned pedicle. The procedure was used to treat 3 defects. Complete root coverage was obtained on 2 of the 3 defects. The third was covered to within 1 mm of the cemento-enamel junction (CEJ). Histology showed similar results with a connective tissue graft and an acellular dermal matrix. Verhoeff's staining demonstrated that the acellular dermal matrix was incorporated into the gingival tissue. This case report demonstrated that acceptable results can be obtained with the connective tissue with partial thickness double pedicle graft and the acellular dermal matrix combined with a coronally positioned pedicle, both clinically and histologically.
多种技术均可实现牙根覆盖。在本病例报告中，一名患者接受了部分厚度双蒂结缔组织移植治疗，实现了完全的牙根覆盖。然而，术后6天患者腭部供区出现出血问题。因此，采用了一种独特的方法来治疗下一个需要牙根覆盖的区域。该手术联合使用了无细胞真皮基质和冠向带蒂瓣。该手术用于治疗3处缺损。3处缺损中有2处实现了完全的牙根覆盖。第三处缺损覆盖至距牙骨质-釉质界（CEJ）1mm以内。组织学检查显示，结缔组织移植和无细胞真皮基质的结果相似。韦尔霍夫染色显示无细胞真皮基质融入了牙龈组织。本病例报告表明，部分厚度双蒂结缔组织移植以及无细胞真皮基质联合冠向带蒂瓣，在临床和组织学上均可取得可接受的效果。
