Introduction: Hydrodynamic piezoelectric surgery is a sophisticated approach to internal sinus elevation that uses a transcrestal technique to reduce postoperative complications such as sinus floor perforation, bleeding, and implant failure.
Materials and Methods: A total of 30 maxillary sinuses (patients with missing molars or premolars) were chosen to meet a set of inclusion and exclusion criteria. The participants were divided into three groups at random by a computer system. Cone-beam computed tomography (CBCT) was performed at all surgical sites to determine the residual bone height between the alveolar bone crest and the sinus floor, as well as the bone width required for the appropriate implant size and location. There was an elevated transcrestal mucoperiosteal flap for all groups. The two study groups underwent sinus elevation procedures with and without bone grafts and simultaneous implant placement using a hydrodynamic piezoelectric internal sinus elevation technique. The control group experienced a sinus floor elevation procedure that included a bone graft and implant placement at the same time. The bone height gained after sinus elevation was assessed by (CBCT) measurements in each group.
Results: Piezoelectric sinus lift revealed good difference in the bone height gained after the Schneiderian membrane elevation with minimal postoperative complications compared to the conventional osteotomes. Changes were found to be statistically significant between the two study groups and the control one.
