Abstract

Purpose: The objective of this study was to assess the clinical and radiographical outcomes of implant placement in the posterior maxilla with insufficient residual vertical height by sinus lifting, either by Osseodensification (OD) or conventional Osteotome (OS) technique. Subjects and Methods: Ten patients with 16 crestal sinus floor elevation were performed with a 5-7mm residual vertical height. Patients were divided randomly into two groups: Group Ι (OD) 6 patients with 8 implants were inserted simultaneously with an osseodensification sinus lift. Group II (OS): 4 patients with 8 implants were inserted simultaneously with a conventional osteotome sinus lift. Cone-Beam Computed Tomography (CBCT) was done preoperatively, immediately, and after 6 months. Implant Stability Quotient (ISQ) was measured in both groups immediately and after six months. The collected results were tabulated and statistically analyzed. Results: There was a significant increase in torque in the OD group than in OS group (p-Value=0.001). There was also a significant decrease in pain immediately (p-Value=0.002) and after 1 week (p-Value=0.001) in the OD group. Regarding apical bone gain, there was insignificant increase in bone gained both immediately in the OD group (p-Value = 0.86) and after six months in bone gained in OS group (p-Value=0.926). In the OS group, marginal bone loss increased insignificantly immediately (p-Value=0.522) but increased significantly after six months (p-Value=0.026). Bone density insignificantly increased in the OS group immediately (p-Value=0.606) but insignificantly decreased after 6 months (p-Value=0.443). Conclusion: Both osseodensification and osteotome techniques showed good clinical outcomes in 6 months follow up.
