[Photoocclusion analysis for the reduction of occlusal table dimension of the pontics].
50 cases of mandibular dentitions with normal morphology and occlusion are analyzed by using photoocclusion. The occlusal surfaces of the molars are divided into four regions buccolingually. That are the buccal inclines and lingual inclines of the buccal and lingual cusps of the molars. The relationship of sigma epsilon value among these four regions is 3:5:2:0 respectively. This indicates that it is effective to get force reduction by adjusting the buccal incline of the pontic in fixed bridge restoration.
