Abstract
Objective: To compare condylar dimensions of young adults with Class II and Class III skeletal patterns using cone-beam computed tomography (CBCT). Materials and methods: 124 CBCTs from 18-30 year old patients, divided into 2 groups according to skeletal patterns (Class II and Class III) were evaluated. Skeletal patterns were classified by measuring the ANB angle of each patient. The anteroposterior diameter (A and P) of the right and left mandibular condyle was assessed from a sagittal view by a line drawn from point A (anterior) to P (posterior). The coronal plane allowed the evaluation of the medio-lateral diameter by drawing a line from point M (medium) to L (lateral); all distances were measured in mm. Results: In Class II the A-P diameter was 9.06±1.33 and 8.86±1.56 for the right and left condyles respectively, in Class III these values were 8.71±1.2 and 8.84±1.42. In Class II the M-L diameter was 17.94±2.68 and 17.67±2.44 for the right and left condyles respectively, in Class III these values were 19.16±2.75 and 19.16±2.54. Conclusion: Class III M-L dimensions showed higher values than Class II, whereas these differences were minimal in A-P.
Highlights
Mandibular condyles, part of the temporomandibular joint (TMJ), may undergo morphological changes throughout the life mediated by functional adaptation
The mandibular condyle in a Class I skeletal pattern is centered in the glenoid cavity and normally measures around 8mm of anteroposterior diameter and 22mm of mediallateral diameter
Some studies suggest that mandibular condyle dimensions are influenced by the masticatory function
Summary
Mandibular condyles, part of the temporomandibular joint (TMJ), may undergo morphological changes throughout the life mediated by functional adaptation. Mandibular condyle dimensions in Peruvian patients with Class II and Class III skeletal patterns. III by a condyle greater than 22mm of medial-lateral was approved by the Ethics Committee of Universidad diameter.[3,4] there are few studies evaluating Peruana de Ciencias Aplicadas (UPC) CEI/032-04-16.
