Awareness about root coverage is increasing in day-to-day clinical practice. Patients are more motivated and concerned about aesthetics nowadays along with the issues of sensitivity of teeth. The conventional flap designs and techniques including lateral sliding flaps, coronally advanced flap, subepithelial connective tissue grafts and free gingival grafts are being adopted for root coverage. The newer material including resorbable and non-resorbable guided tissue regenerative membranes, amniotic membrane, platelet-rich fibrin membrane, enamel matrix derivative protein, xenogenic collagen matrix graft along with the soft tissue substitute like acellular dermal matrix allograft are also being used for recession coverage. The present case report describes a case of 22-year-old female patient with the chief complaint of denudation of gums exposing the root surface over the mandibular left central incisor. The soft tissue substitute acellular dermal matrix allograft was used for root coverage as the patient was not willing to procure an autogenous palatal graft. The results were satisfactory with complete root coverage.
在日常临床实践中，人们对牙根覆盖的认识正在提高。如今，患者不仅更加关注牙齿的敏感性问题，还更加关注美观和敏感性。传统的皮瓣设计和技术，包括侧向滑行瓣、冠向推进瓣、黏膜下结缔组织移植和游离龈移植，都被用于牙根覆盖。较新的材料，包括可吸收和不可吸收的引导组织再生膜、羊膜、富含血小板纤维蛋白膜、釉基质衍生蛋白、异种胶原基质移植物，以及无细胞真皮基质同种异体移植物等软组织替代物，也被用于牙龈退缩覆盖。本病例报告描述了一位 22 岁女性患者的病例，其主要诉求是下颌左侧中切牙牙龈退缩，露出牙根表面。由于患者不愿意获取自体腭部移植物，因此使用软组织替代物无细胞真皮基质同种异体移植物进行牙根覆盖。结果令人满意，完全实现了牙根覆盖。
