Research have indicated that inadequate keratinized tissue has a negative effect on patient oral hygiene, resulting in peri-implant inflammation. It has been recommended that an apically repositioned flap alone or in combination with autogenous soft tissue grafts can increase the width of keratinized mucosa around dental implants, which promotes long term peri-implant health. This review summarized research progress on augmentation techniques of keratinized tissue arround implants in recent years, so as to provide reference for clinical practice and research design in the future.
已有研究表明，种植体周围角化组织宽度不足可能不利于患者口腔卫生措施的实施，易引起种植体周围组织炎症。有学者建议采取根向复位瓣或联合软组织移植等手术方式增加种植体周围角化黏膜宽度，促进种植体周围组织的健康。本文综述了近年来种植体周围角化组织增宽术的研究进展，以期为今后的临床实践和研究设计提供指导。.
