Topographic analysis of the mandibular canal in coronal section, in the region of molars

Abstract

The studies about bone resorption contributed greatly to the advancement of rehabilitation with dental implants and Buccomaxillo facial Surgery and Traumatology. This phenomenon leads to a more superficial localization of the mandibular canal in relation to the alveolar ridge when teeth are lost, limiting and hindering the installation Bone tissue, of implants, as well as other surgical procedures. This anatomical study aimed to analyze and interpret the distances from the mandibular canal to the alveolar ridge, in groups of dentate individuals and toothless, comparing them statistically, so 20 adult male cadavers divided into two groups, namely group A, formed by 10 dentate and group B, consisting of 10 toothless individuals. All their teeth were dissected and then, were checked the measurements of the distances between the roof of the mandibular canal and the alveolar ridge. The averages found were enlightening to say that bone resorption has consequences for treatment and surgery for dental implants, due to the decreasing bone support for the implantation and other surgical procedures, increasing the risk of injury to the inferior alveolar neurovascular bundle.
