| Research Abstract |
This study was undertaken to examine the effects of mechanical loadings on the morphology of mandibular condyle following distraction in rat experimental model.10-week-old male Wistar rats received 3.5 mm unilateral mandibular distraction over 10 days after5-day latency period, and the morphological changes of mandibular condyles were examined one day, one week and three weeks after distraction. As a result, the deformation of the condyle with a destruction of cartilage layer and a bone resorption was recognized. These findings indicate thatoverloading to the mandibular condyle is a key factor for PCR.
