Abstract
The purpose of this study is to investigate the cross-sectional anatomy of posterior mandibular body for proper determination of bucco-lingual Implant path using fifty-four human mandibles, negative images of each mandible were made of agar impression material The agar blocks were cut through the imaginary long axis of each root of three molars (MIM, MID, M2M, M2D and M3) The depth of submandibular fossa, the angulation of long axis of mandibular body and tooth, and the length, angulation and ratio of alveolar bone superior to mylohyoid ridge and basal bone inferior to mylohyiod ridge were measured The results obtained were as follows, 1 All of the measured angulations were decreased as it moves from M1M to M32 The correlation coefficients among the angulation of the mandibular bone and the crown axis showed the high relationship (r=O 793), and the crown axis was steeper than the mandibular bone axis by 6 2° at M1M and 7 6° at M2M3 The length of upper alveolar bone was decreased, but that of inferior basal bone was increased as it moves from MIM to M34 The depth of submandibular fossa was increased as it moves from MIM to M3 These results indicate that the angulation of implant path at the posterior mandible must be tilted more than wax-up crown axis by 6 2° at mesial root of 1st molar and by 7 6° at mesial root 2nd molar area for prevention of lingual cortical bone perforation during Implant surgery.
