Abstract:
Objective To study the effect of functional mandible shift on mandible development in pubertal rats.Methods Forty-eight male Sprague-Dawley rats at the age of 28 d were randomly divided into experimental group (n=24) and control group (n=24).Maxillary occlusal splints were designed to simulate mandible shift in experimental group.Six rats in each group were killed after 7,14,21,and 28 days,respectively.Right and left mandibles were removed for X-ray radiography and localizing points.Distance between the points was measured with an image analyzer.Results Fourteen days from experiment,the length parameters of the non-shifted mandible(Cd-Me,Co-Me,Go-Me)were significantly higher than those of the shifted mandible length in rats of experimental group(P
