Masticatory Function Following Fractures of the Mandibular Condyle

摘要

Gnathodynamic analyses of function of the masticatory system using several testsof oral-motor function were examined in a sample of controls, and two groups of patients treated for fractures of the mandibular condyle. Patients were treated with either open reduction and internal fixation of their fracture or with closed reduction. Among patients treated non-surgically, deviation of the mandible towards the side of fracture was noted during opening of the mouth. Among those patients treated surgically, deviation of the mandible away from the side of fracture was noted. These results indicate that parameters of masticatory function, with a few exceptions, do not differ in patients treated with or without surgery for fractures of the mandibular condyle.
