Abstract:
Most researchers agree that the primate temporomandibular joint (TMJ) is loaded compressively during function and that condylar position must play a role in mediating such loads. However, the precise nature of that role remains unclear. Using a pig model in this study, we attempted to analyze strain on the neck of the condyle during normal mastication and during simulated function in different condylar positions. Miniature three-element rosette strain gauges were bonded to the lateral surface of the condylar neck in 4 female miniature pigs (one per condyle). Measurements of strain were made du

Background/Aim. Postoperative condylar position is a substantial concern in surgical correction of mandibular prognathism. Orthognathic surgery may change condylar position and this is considered a contributing factor for early skeletal relapse and the induction of temporomandibular disorders. The purpose of this study was to evaluate changes in condylar position, and to correlate angular skeletal measurements following bimaxillary surgery. Methods. On profile teleradiographs of 21 patients with mandibular angular and linear parametres, the changes in condylar position, were measured during pr
