CBCT Evaluation of the TMJ Pre- and Post-Orthognathic Surgery
Abstract
Introduction: When post-orthognathic surgical condylar remodeling exceeds a patient's physiological ability to adapt, it may lead to surgical relapse and/or be associated with temporomandibular joint disorders (TMD) 1 2 3. Purpose: This retrospective analysis will evaluate if resorptive changes within the temporomandibular joint (TMJ) are detectable with cone-beam computed tomography (CBCT) following orthognathic surgery (OGS). Methods: CBCT provides 3D imaging of hard tissues and can reveal morphologic changes of the condyle and the glenoid fossa as a result of bone remodeling when scans are compared over time. Geometric morphometric analysis of superimposed landmark based wireframes generated from CBCT scans will allow for the generation of deformation grids and heat maps to visualize shape differences and changes. Once segmented, inter-surface distance calculations will be measured between the superimposed 3D mesh models for quantitative and qualitative statistical analysis. Results: To date, no results have been collected.
