Studying the effects of Bite plane application in intruding and extruding the teeth in patients with deep bite

Deep bite is a major clinical problem manifested as higher than normal overbite in anterior region of the jaws. Various studies were conducted to identify the effects of using bite plan and its results. 14 subjects with deep bite were selected out of 400 students of a school who had not proximal caries and had not lost any permanent teeth with healthy periodontal condition. 8 patients were considered as case group and the 6 other as the control group. In case group, a simple labial arc with acrylic palate that caused a gap in occlusion was placed. 2 lateral radiographs were obtained both pre and post 14 months treatment period. After cephalometric analysis, due to bite plane application significant intrusion in mandibular incisors were observed as well as elongation in both maxillary and mandibular molars.
