光学相干断层扫描用于评价口腔种植区软组织质量的研究进展

Research Progress of Optical Coherence Tomography on Evaluating Soft Tissue Quality in Oral Implantion Area.

口腔拟种植区软组织质量评估可初步预测种植术后的美学效果、边缘骨吸收情况、种植体周围病变的发生等。近年来对软组织质量的评估一直处在不断探索实践中,光学相干断层扫描(optical coherence tomography,OCT)利用光学原理对所检查对象进行投射,光线穿透牙龈,向后散射获取软组织数据,通过计算机软件转化为二维(two-dimension,2D)或三维(three-dimension,3D)图像,清楚显示软组织结构,对拟种植区软组织质量可进行初步评估。本文拟概述OCT在口腔种植术前牙龈厚度(gingival thickness,GT)、角化黏膜宽度(keratinized mucosa width,KMW)、牙槽嵴上软组织高度(supracrestal tissue height,STH)、牙龈软组织炎症方面的应用及研究进展。

The quality of soft tissue in the oral implantation area can be used to preliminarily predict the aesthetic effect,marginal bone resorption,and the occurrence of peri-implant lesions after implantation.In recent years,the evaluation of soft tissue quality has been in constant exploration and practice.Optical coherence tomography uses the optical principle to project the examined object,and the light penetrates through the gum and backscatteringly obtains soft tissue data,which is converted into 2D or 3D images through computer software to clearly show the soft tissue structure.The quality of the proposed implantation area can be preliminarily evaluated.This article reviews the application and research progress of OCT in evaluating gingival thickness,keratinized mucosa width,supracrestal tissue height,and gingival soft tissue inflammation before oral implantation.
