Brief Summary

The placement of implants in the symphyseal region is common, especially in the treatment of totally edentulous patients. Some implant surgical procedures may however be responsible for lesions of the vascular and nervous elements in the symphyseal region. The prevention of vascular and nervous accidents during or after implant surgery is based on the identification of vascular and nervous elements. Although the anatomy of the symphyseal region is rather well described in the literature, the data concerning totally edentulous patients remains fragmented. These suggest that tooth avulsion and bone resorption have an influence on the anatomy of the mandibular region, and of the vascular and nervous elements traveling in the anterior mandibular part. These modifications would be responsible for individual anatomical variations. In order to test this hypothesis, the investigator wish to evaluate the anatomical characteristics of the vascular and nervous elements located in the symphyseal region, retrospectively, of a totally edentulous population for which the anatomy was documented in a three-dimensional way from 2013 to 2021 before the placement of dental implants.
