Summary:During implantology procedures, one of the most serious complications is the damage of the inferior alveolar nerve, which may result in neurosensory disturbances (NSD). Panoramic radiographs have been considered for a primary evaluation to determine the bone height and implant-mandibular canal distance. One thousand five hundred ninety-seven panoramic radiographs of patients, who were treated with 3608 dental implants in Erciyes University, Oral and Maxillofacial Hospital between 2007 and 2012, were examined. Forty-eight implants were determined to be near the mandibular canal using a 2-dimensional software program. A total of 48 implants were closer than 2 mm to the mandibular canal. A range of 0 to 1.9 mm distance was detected between the mandibular canal and these implants. Fourteen implants (29.16%) placed in a distance less than 1 mm to the mandibular canal, and 34 (70.83%) between 1 and 2 mm. One patient had NSD. Determination of the dental implant length using panoramic radiography is a reliable technique to prevent neurosensory complications. However computed tomography or cone-beam computed tomography based planning of dental implants may be required for borderline cases.
