Damaged sensory nerves in the facial area might show spontaneous recovery. However, imperfect regeneration, such as paresthesia, numbness, and painful pathologic regeneration can occur in some cases. Therefore, iatrogenic nerve damage should be avoided during implant placement in patients with alveolar bone atrophy. For placement of implants in the posterior area of the mandible, the corresponding anatomical structures including the inferior alveolar nerve are of concern. Herein, we presented a case of a patient who developed traumatic neuroma after undergoing full mouth rehabilitation with implants in another hospital. Treatment at our facility included the removal of all implants posterior to the mental foramen, followed by an autogenous iliac bone graft performed on the atrophied alveolar ridge of the mandible. Subsequently, implants were placed in the grafted sites. Finally, the patient showed functional and esthetic results.
