种植体周角化组织增宽的临床意义和研究进展

种植体周角化组织宽度不足是种植修复过程中常见的问题。已有研究表明，充足的角化组织宽度不仅利于菌斑控制，还可提高种植体的长期稳定性。目前，临床中用于角化组织增宽的术式主要有：根向复位瓣术、自体组织移植和异体组织移植等。本文就种植体周角化组织宽度的意义及各类角化组织增宽术的研究进展作一综述，以期为临床诊疗提供借鉴。

Clinical significance and research progress of peri-implant keratinized tissue augmentation

Insufficient width of peri-implant keratinized tissue is a common problem of implant restoration.Previous studies have shown that sufficient keratinized tissue width is not only conducive to the control of plaque,but also can improve the long-term stability of implants.At present,the main approaches to increasing the width of keratinized tissue in clinical practice are:apically repositioned flap,autologous tissue transplantation,allogeneic tissue transplantation,etc.This review summarized the significance of peri-implant keratinized tissue width and the progress of research on various methods of keratinized tissue,providing reference for clinical diagnosis and treatment.
