This retrospective clinical study presents the results achieved with piezosurgery, applied to the transposition of the mental nerve (TNM), associated with phototherapy to reduce hyperalgesia in an elderly denture patient. TNM surgical procedure was proposed to improve hyperalgesia caused by involution of the alveolar bone and superficialization of the neurovascular bundle by employing osteotomy with piezoelectric system and postoperative phototherapy. The patient received applications of LED (GaAlAs, 640 ± 20 nm, 0.1 W, 20 s, 2 J) for 30 min and 48 h after surgery, due to bilateral paresthesia of the mental region. Beginning on the fifth postoperative day, the patient was subject to weekly laser therapy (GaAlAs, 795 nm, 0.1 W, 40 s, 4 J). Phototherapy was employed to control the inflammatory process (2 J, LED) and stimulate tissue repair (4 J, laser). Two months after surgery, the patient was painfree and with minimal unilateral paresthesia (<5%). The association of piezosurgery with phototherapy was effective in the transposition of the mental nerve. There was reduction of pain, fast neuronal repair with reduction of postoperative paresthesia, improved quality of life, with increased ability for eating, social interaction, and motivation for the patient treated.
