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

Abstract

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.
