Poster 52: Lateral Cortical Bone Thickness of the Dentate Human Mandibles in the Region of the Mental Foramen: The Proposal of a New Plate Design

Abstract

Statement of the Problem: In parasymphyseal fractures near the mental foramen, the use of a monocortical malleable four-hole miniplate placed above and below at its border has been indicated to prevent tension and torsion forces. However, in this region limited space is available for two miniplates and for anatomical reasons, it is sometimes difficult to avoid damage to teeth roots or the inferior alveolar nerve. The purpose of this study was to verify the cortical thickness and the presence of the teeth's roots and inferior alveolar canal where miniplates are placed according to Champy's technique in the treatment of parasymphyseal fractures between canine and premolar, and to verify the cortical thickness and the presence of noble structures anteriorly and posteriorly of the mental foramen as the same height of it.
