Abstract:
Objective To discuss the effect of the shape of mandibular arch on uprightness distortion ratio in computed orthopantomography.Methods 20 specimens of adult head with different shape of mandibular arch were selected.The computed orthopantomography was performed after the markers were inserted in the marking points of mandible,the length of the markers were measured with computer,and the results were statistically analysed.Results In computed orthopantomography,the uprightness distortion ratio of anterior teeth area of square mandibular arch(11.77%) was higher than that of tine mandibular arch(5.05%),and the difference was prominent(P=0.011
