[Inferior alveolar nerve lateralisation in pre-implantation surgery]

The inferior alveolar nerve remains an anatomical obstacle for implant insertion in the posterior part of the mandible. Inferior alveolar nerve lateralisation allows new implant-borne prosthetic alternatives, after a careful radiological check-up and for an adapted prosthetic project, for removable and fixed prostheses. We present the infra-alveolar nerve lateralisation technique, its indications and contra-indications. This technique completes the armamentarium of surgical techniques for the correction of inferior molar edentulism.
