错畸形患者髁突位置及正畸治疗前后髁突位置变化的CBCT评估
Evaluation of condylar position in patients with malocclusion and changes in condylar position before and af-ter orthodontic treatment using cone beam computed tomography
摘要
Abstract
The functional health and stability of the oral and maxillofacial system is one of the basic goals of orth-odontic treatment.Currently,it is believed that,in general,the condyle is located in the center of the joint fossa when the mandible is in an intercuspal position(ICP)in healthy normal people.At this time,the function of the temporoman-dibular joint(TMJ)is stable.Due to orthodontic tooth movement and subsequent occlusal changes,patients with maloc-clusion may experience related remodeling of the temporomandibular joint,especially changes in the position of the con-dyle.The position of the mandibular condyle is traditionally evaluated using a condylar position indicator.However,this method lacks consistency in obtaining condylar position changes.In recent years,in the clinical application of orthodon-tic treatment,cone beam computed tomography(CBCT)has become the first choice for examination.CBCT can accurate-ly measure the interarticular space and determine changes in condylar position.This article reviews the CBCT assess-ment of condylar position and related research on condylar position changes in patients with malocclusion before and af-ter orthodontic treatment.The literature review results indicate that there are differences in the condylar position of pa-tients with different malocclusions,and the condylar position may also change before and after orthodontic treatment.With a lower radiation dose,CBCT has higher accuracy in evaluating the condylar position in patients with malocclu-sion who undergo orthodontic treatment,thus promoting further study of the mechanism of condylar position changes in patients with malocclusion in the future and providing more accurate and personalized guidance for patient treatment.关键词
