Objective: Evaluation of implant stability, vertical and horizontal bone gain and bone density using osseodensification technique versus Piezosurgery in transcrestal maxillary sinus lifting.
Subjects & Methods: Twenty-two patients were included in the study and randomly divided into 2 equal groups: Group 1: 11 patients treated by densah drills (Versah, Jackson, MI, USA) transcrestal sinus lift with bone grafting (xenograft) and implant placement. Group 2: 11 patients treated by piezoelectric transcrestal sinus lift (Piezotome; Satelec) with bone grafting (xenograft) and implant placement. CBCT radiograph was done before and after 6 months of dental implant placement.
Results: Both groups showed statistically significant differences from baseline to 6 months. osseodensification showed a better technique for gaining better implant stability and bone density. Both groups showed no difference in both vertical and horizontal bone gain.
Conclusion: Osseodensification and piezoelectric surgery are both effective methods for crestal sinus elevation, with higher implant stability and bone density in the osseodensification group after 6 months.
