The immediate loading of the implants was satisfactory, and both splinting conditions (rigid and semi-rigid) can be successfully used for the restoration of edentulous mandibles.

The aims of this article were to describe the surgical technique of the inferior alveolar nerve lateralization followed by implant installation by means of a clinical report and also to discuss the importance of an adequate surgical and prosthetic planning for atrophic posterior mandible rehabilitation.

There was slight qualitative and quantitative bone improvement in the posterior area of the mandibles with the use of immediately loaded implant-supported fixed prostheses during the observed period. These results suggest that long-term follow-up is very important to understand bone behavior after rehabilitation.
