| Abstract: | Objective: The purpose of this study is to evaluate the cranio facial adaptational changes after mandibular functional protrusion in the young rats. Method:Thirty 4 weeks old wistar rats were selected to wear the functional appliance to protrude the mandible for four weeks. The cephalometric method was applied to measure the changes in rat cranio facial morphology during the 4 weeks. Results: The length of the mandible showed: increasing trend and its position move anteriorly. The alveolar bone elevated. Concusion:This indicates that the remodelling of morphology and the cranio facial growth were influenced distinctly after mandibular functional protrusion in the rat. |
