Persistent numbness of the lower lip and chin due to inferior alveolar nerve injury after implant placement: A clinical report.

The number of dental implants placed and restored every year is increasing across the world. However, there has been an increase in the number of reports with implant-related surgical complications in which the inferior alveolar nerve injury is the most serious one. This surgical problem can be avoided by using cone beam computed tomography (CBCT), three-dimensional (3D) implant planning software, and computer-aided design and computer-aided manufacturing (CAD-CAM) technology such as stereolithographic surgical guides. The objective of this report is to present the clinical and radiologic findings of a female patient with the injury of inferior alveolar nerve after implant insertion where CBCT has not been used prior to implant placement.
