Surgical complications associated to maxillary sinus floor elevation in implantology

Abstract

Maxillary sinus floor elevation has been extensively documented as a safe and predictable procedure for gaining vertical bone height in the atrophic posterior maxilla. Even though, complications have been reported, which can potentially jeopardize the outcome of the regeneration and implant therapy. Therefore, the purpose of this literature review is to present, debate and analyze the different complications that can occur during a sinus floor elevation.
