Lateralization Technique and Inferior Alveolar Nerve Transposition.

Bottom Line: Bone resorption of the posterior mandible can result in diminished bone edge and, therefore, the installation of implants in these regions becomes a challenge, especially in the presence of the mandibular canal and its contents, the inferior alveolar nerve.The aim was to elucidate the success rate of implants in the lateralization technique and in inferior alveolar nerve transposition and to determine the most effective sensory test.We conclude that the success rate is linked to the possibility of installing implants with long bicortical anchor which favors primary stability and biomechanics.

ABSTRACT
Bone resorption of the posterior mandible can result in diminished bone edge and, therefore, the installation of implants in these regions becomes a challenge, especially in the presence of the mandibular canal and its contents, the inferior alveolar nerve. Several treatment alternatives are suggested: the use of short implants, guided bone regeneration, appositional bone grafting, distraction osteogenesis, inclined implants tangential to the mandibular canal, and the lateralization of the inferior alveolar nerve. The aim was to elucidate the success rate of implants in the lateralization technique and in inferior alveolar nerve transposition and to determine the most effective sensory test. We conclude that the success rate is linked to the possibility of installing implants with long bicortical anchor which favors primary stability and biomechanics.

Mentions: The patient was advised to make use of anti-inflammatory nimesulide (nimesulide, Medley, 100 mg), 1 tablet every 12 hours for 5 days, and analgesic dipyrone (sodium dipyrone, Medley, 500 mg), 30 drops every 6 hours for 2 days. After surgery, a CT scan was performed to evaluate the implant (Figures 31 and 32). Twenty four hours postoperatively, the patient had no pain—only a small, localized edema. In the evaluation of sensorineural disorder, a directional test with a brush and light touch pressure with a gutta percha cane were used (Figure 33). In the directional test, the patient was able to distinguish the direction of the vertical and horizontal movements. The light touch test served to demarcate the area corresponding to the sensory change. During examination in the 24-hour postoperative period, the patient suggested a hypoesthesia frame. At the 14-day follow-up, there was a decrease in the area corresponding to the sensory abnormalities, which occurred again at the 28-day follow-up. After three months, the patient had no sensory damage (Figure 34).
