Pain Caused by a Dental Implant Impinging on an Accessory Inferior Alveolar Canal: A Case Report

This report presents a case history of intractable facial pain following the placement of a posterior mandibular implant. The pain was resistant to all medical management, but a cone beam computed tomography (CBCT) scan showed that the implant impinged on an unusual accessory inferior alveolar nerve. The decision to remove the implant led to significant pain reduction. This clinical example underscores the need for scrupulous imaging prior to implant placement.
