Highlights

•	Sexual Dimorphism is found in mediolateral condylar diameter (MLD), with males showing higher MLD.
•	Mediolateral condylar diameter is correlated with the condylar morphology in the coronal anatomic plane.
•	There is no relationship between condylar morphometry and Sagittal intermaxillary relationship.

Summary

Objective

This study established the morphometry of the mandibular condyle in individuals with complete craniofacial growth and sagittal intermaxillary relationships class I, II and III using cone beam computed tomography (CBCT).

Materials and methods

Cone beam computed tomography was obtained for orthodontics diagnostic purposes. The sample was divided taking into account the ANB angle in sagittal classes I, II and III (age ranged from 18 to 40 years old). Linear measurements and shapes of 144 mandibular condyles were analyzed.

Results

Statistically significant differences were found in measurements of the mediolateral diameter when compared with gender (P 0.000) being larger for males. Statistically significant differences between the mediolateral diameter and the coronal shape for the right as well as the left sides with P values of 0.000 and 0.47 respectively were found.

Conclusion

In this sample, it was not possible to conclusively determine the relationship between the skeletal class and the mediolateral diameter. However, more studies are required.
