Abstract :

Introduction: Accurate buccal cortical one thickness is required is required in various procedures like miniplates and monocortical screw fixation during treatment of mandibular fracture. It is aalso evaluated during fixation of cortical implants. With the innovation of CBCT accuracy of these measurements has increased greatly. Material and methods: The retrospective study of 120 cbct scan 60 males and 60 females was done. Buccal cortical plate and trabecular bone thickness were measured at following locations : Canine ( C) First Premolar ( PM) , First molar ( M1) and Second Molar (M2). Measurements were made using a digital ruler aligned perpendicular to the cortex in cross-sectional views at the above locations. A statistical analysis was carried out using (SPSS) version -20 software. The means and standard deviation of data obtained was calculated. Result: Among all the areas evaluated , width was greatest at the second molar region with 4.53 � 1.51 at the level of mid apical third of the tooth root, 6.99 � 1.07 at the level of root apex, 5.23 � 1.45 at the level of inferior alveolar nerve canal . Conclusion Buccal cortical thickness measurement should be imperative before treatment of mandibular fractures and for preoperative assessment of cortical implant fixation for succesfull treatment outcome.
