BACKGROUND: The treatment of the condylar @entity174 is difficult. Factors that result in the @entity174 are complex. The objective of this morphometric study was to investigate the relationship between condylar @entity174 patterns and condylar morphological characteristics. METHODS: We conducted a retrospective analysis of 107 @entity1 admitted to the West China Hospital of Stomatology for @entity174 caused by parasymphyseal impact. The @entity1 were divided into five groups according to the type of condylar @entity174 . Ten parameters were evaluated on three-dimensional (3D) reconstruction mandible models through the Mimics 16.0 (Materialize Leuven, Belgium) anthropometry toolkit. Each parameter of the 3D models was analyzed using multivariate analysis. Multinomial logistic regression analyses were used to examine the relationships between the five groups. RESULTS: The results showed that the differences of condylar head width (M1), condylar neck width (M3), the ratio of condylar head width to condylar anteroposterior diameter (M1/M2), the ratio of condylar head width to condylar neck width ( @entity25089 ), the ratio of condylar height to ramus height (M8/M7), and mandibular angle (M10) were statistically significant (p < 0.05). Type A condylar head @entity174 were positively associated with M1 (compared to Type B: OR =1.627, 95% CI: 1.123, 2.359; compared to Type C: OR = 1.705, 95% CI: 1.170, 2.484) and M1/M2 (compared to Type B: OR =1.034, 95% CI: 0.879, 2.484). Type B condylar head @entity174 were negatively associated with M10 (compared to Type C: OR = 0.909, 95% CI: 0.821, 1.007). @entity174 were negatively associated with M3 (compared to condylar head: OR = 0.382, CI: 0.203, 0.720 ; compared to condylar base: OR = 0.436, 95% CI: 0.218, 0.874), and positively associated with @entity25089 (compared to condylar head: OR = 1.229, 95% CI: 1.063, 1.420 compared to condylar base: OR = 1.223, 95% CI: 1.034, 1.447). Condylar base @entity174 were positively associated with M10 (OR = 1.095, 95% CI: 1.008, 1.189) and negatively associated with M8/M7 (OR = 0.855, 95% CI: 0.763, 0.959) as compared with condylar head @entity174 . CONCLUSIONS: Condylar @entity174 pattern is associated with the anatomical features of the condyles when a @entity174 occurs from parasymphyseal impact.
