On the pterygoid implant savior for failed implant-rehabilitations – A surgical case series with technical notes

Abstract

Implant failure in the maxilla often determine significant bone loss. Patients that had already experienced regenerative surgeries such as sinus lift and/or the placement of zygomatic implants may want to avoid further complicate rehabilitation protocols. Pterygoid implants, when feasible, offer the unique opportunity of immediate loading bypassing the maxillary sinuses an extending the anterior-posterior spread of the future prosthesis. The present case series documented the long-term success of pterygoid implants in the rehabilitation of patients who had experienced the failure of zygomatic implants and standard implants in the posterior maxilla.
