Lateralization Technique and Inferior Alveolar Nerve Transposition.

Pimentel AC, Sanches MA, Ramalho GC, Roman-Torres CV, Manzi MR, Sendyk WR - Case Rep Dent (2016)

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.

fig2: Computed tomography (cone beam) of the jaw, right side.

Mentions: Osteotomy. Using CT (cone beam), the molar regions of the right jaw were observed and cutting lines for the osteotomy were planned for the remaining bone volume with 5.4 mm thickness and 4.8 mm height (Figure 2). Using a ruler, needle point, and a pencil of sterilizable graphite, it was possible to plan and carry it to the surgical area, thus delimiting the mental foramen and the mandibular canal, the vestibular bone surface of the body jaw, always with a 2.0 mm safety margin for all traits (Figure 3). The lateral osteotomy to the mandibular canal was performed on the lines of the piezoelectric ultrasound using the tip OT 7 for bone cutting, involving the mental foramen, extending to the cancellous bone (Figure 4). During osteotomy, irrigation was performed with sterile distilled water.
