牙龈乳头缺失产生的黑三角问题是临床治疗上最棘手的问题之一。龈乳头的缺失与邻接点到牙槽嵴顶的距离密切相关。非手术治疗方法通过正畸、修复的技术改变邻接点位置缩小黑三角,手术方法则通过结缔组织移植、骨移植、或生物活性材料应用,结合冠向复位瓣等手术技术实现软硬组织增量,增加龈乳头高度。本文就龈乳头重建手术的研究进展作一综述。
The black triangle caused by the loss of gingival papilla is one of the most intractable problems in clinical treatment. The absence of gingival papillae is closely related to the distance between adjacent points and the alveolar crest. Non-surgical treatment of orthodontic, repair techniques to change the location of adjacent points to reduce the black triangle, surgical methods through the connective tissue transplantation, bone transplantation, or bioactive materials, combined with coronal reduction flap and other surgical techniques to achieve soft and hard tissue increments , Increase the height of papilla. This article reviews the research progress of the papilla reconstruction operation.
