Piezoelectric surgery in maxillary sinus floor elevation with hydraulic pressure for xenograft and simultaneous...

Because of the low bone quality in the posterior maxilla, edentulism in this area often results in a resorbed osseous structure and a pneumatized maxillary sinus, which makes dental implant surgery in the posterior maxilla a challenge. Two main surgical approaches are available for the sinus lift procedure: lateral and crestal. Improvement of the maxillary sinus floor elevation technique and increase in predictability are desirable. This article describes an innovative approach to maxillary sinus floor elevation with piezoelectric surgery and hydraulic pressure for xenograft and simultaneous implant placement in situations with insufficient residual alveolar bone.
