The rehabilitation with oral implants is, without any doubt, a consecrated technique. But often we face situations of high bone atrophy where the conventional installation of dental implants is not possible. The posterior mandible, when severely resorbed, generally requires complex techniques to be rehabilitated with implants, such as the lateralization of the inferior alveolar nerve. As an option for these cases, this paper proposes the use of short implants for the rehabilitation of severely resorbed posterior mandible.
