Clinical Science and Techniques

The aim of this case report was to describe the inferior alveolar nerve (IAN) lateralization technique using the piezoelectric device for the posterior rehabilitation of an atrophic mandible with implants. The patient presented the absence of elements 35 and 36 associated with a vertical defect impairing the adequate dental implant placement without IAN damage. A full-thickness mucoperiosteal flap was raised, and a bone window was made with a piezoelectric device centralized on the IAN canal position. After dissection, the IAN was moved buccally with a sterile elastic strip. Morse cone 4.0 × 1.5-mm implants were inserted while the IAN remained retracted. At the 4-month follow-up, the screw-retained prosthesis was installed guaranteeing the recovering masticatory function. In conclusion, the case report showed that the IAN lateralization performed with an adequate surgical technique can be successfully indicated for longer implant placement in edentulous atrophic posterior mandible with no permanent neural damage.
