The development of biomaterials, especially of hydroxyapataite (HAP) has recently been remarkable. Although HAP has been used for alveolar ridge augmentation of the edentulous patients with a severely resorbed alveolar ridge, by a subperiosteal tunneling technique, complications with its use have arised. We have experienced a case of neurosensory disturbances following bilateral lower alveolar ridge augmentation with HAP granules and reported on it with some comments based on the literature. A 77-year-old female was admitted to our clinic because of neurosensory disturbances in bilateral lower lip and mental regions. About one year previously, she was given bilateral lower alveolar ridge augmentation with HAP granules. After this operation, neurosensory disturbances in bilateral lower lip and mental regions continued. As compression of mental nerve of HAP granules was suspected, the subperiosteally augmented HAP granules were removed from the buccal aspect of cuspid-premolar regions above and below the mental foramen and the mental neurovasucular bundles were transpositioned below the mental foramen. During the operation, the augmented materials were found to be strongly attached to the boney ridge. Consequentially, the neurosensory disturbances were reduced. Therefore, when the neurosensory disturbances of mental nerve in alveolar ridge augmentation with HAP granules is anticipiated the mental neurovascular bundles should be transpositioned in advance below the mental foramen or oral surgeons should be selected another method.
