Which part of the mandible has the highest incidence of fracture?

The condyle of the mandible has the highest incidence of fracture primarily due to its anatomical position and function. The condylar region is a common site for trauma because it is situated at the joint where the mandible connects to the skull. This area is subject to significant forces during impacts, such as those from sports injuries, falls, or vehicular accidents.

In addition, the condyle's location makes it more vulnerable to direct forces that can result in fractures, especially in cases of trauma where the mandible absorbs shocks. The condyle also acts as a pivotal point for the movement of the jaw, further making it susceptible during sudden or forceful movements.

Other parts of the mandible, such as the angle, body, and ramus, can certainly experience fractures as well, but studies have indicated that condylar fractures are more prevalent due to the combination of anatomical and functional factors, along with the overall mechanics of jaw movement and common traumatic incidents.
