Summary

The aim of the study is to evaluate the relationship between submandibular fossa depth and gonial angle measurements in cone beam computed tomography examinations in terms of dental implant applications. Cone-beam computed tomography images of 51 dry human mandibles were included in the study.

Detailed description

Gonial angle and fossa depths were determined and evaluated separately for left and right sides. Gonial angle was measured on Cone-beam computed tomography images as the angle between the tangent line drawn posterior to the border of the ramus of the mandible and the tangent line drawn to the lower border of the mandible. Determination of the submandibular fossa depth was made with a line was drawn to connect the most dislocated upper and lower points on the inner surface of the mandible in the coronal plane sections, and the length of the line drawn at a right angle from the deepest point of the fossa to this line. Measurements were made separately for left and right sides.
