Research Progress of Optical Coherence Tomography on Evaluating Soft Tissue Quality in Oral Implantion Area
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,supracrest-al tissue height,and gingival soft tissue inflammation before oral implantation.
