Morphological study is a common approach in the field of anterior disc displacement (ADD) pathology; however, analysis based on three-dimensional reconstructive imaging has not been investigated. This study investigated the association between ADD and the status of the mandibular condyle and articular fossa.Thirty-four patients were divided into a normal articular disc position (NADP) group, an ADD with reduction (ADDwR) group, and an ADD without reduction (ADDwoR) group. Images reconstructed were used to determine multiple grouped comparisons of these three different types of disc position, and the diagnostic efficacy for the morphological parameters with significant grouped difference was analyzed to assess.The condylar volume (CV) and condylar superficial area (CSA) of the NADP, ADDwR, and ADDwoR groups exhibited obvious changes (P.05). A multivariate logistic ordinal regression model showed that the CV (odds ratio [OR], 1.011; regression coefficient [RC] = .011, P = .018), superior joint space (SJS) (OR, 8.817; RC = 2.177; P.001), and medial joint space (MJS) (OR, 1.492; RC = 0.400; P = .047) had a significantly positive impact on the groups.The mandibular condyle and articular fossa in temporomandibular joint (TMJ) ADD exhibited altered dimensions. The CV, CSA, SJS, and MJS could be considered as promising biometric markers for assessing ADD, which were investigated in this current pilot study. |
