Abstract:
Implantology allows edentulous patients to smile and chew with confidence. However, the atrophy at posterior region of the mandible is still a challenge due the presence of the inferior alveolar nerve (iAN). The options of restoration with oral implants in this area with great atrophies are few and hazardous. The possibilities are: bone grafting, short implants, which are not always possible. So, the solution falls on the techniques of inferior alveolar nerve lateralization (IANL) or transposition. The knowledge of the anatomy and path of the IAN is decisive in this type of surgery. But anatomical variations may occur. Like the presence of an accessory mental foramen. This clinical study will present a relatively rare case of the occurrence of an accessory mental foramen that obliged to change the technique of iAN lateralization to contour this anatomical variance and install oral implants, maintaining the integrity of the iAN bundle.
