Abstract
Objectives: This study was aiming to evaluate primary stability of implant in closed sinus lifting cases by Densah bur in comparison to Osteotome in partially edentulous patients. Material and methods: This study was conducted on ten patients. The patients were divided into two equal groups. Each patient was received 1 implant at the edentulous site of missing first or second maxillary molar. One group received dental implants using closed sinus lifting by Osteotome while the other group received dental implants using closed sinus lifting by Densah bur. After implant placement, Smart peg is placed on implant and Ostell is used to record ISQ. Implant stability was measured intraoperative and at week 2, 4, 6, and 8 for both groups. The collected results were tabulated and statistically analyzed. Results: The study results showed that there was no statistically significant difference between (Osteotome) and (Densah bur) groups in ISQ reading except at week 4 where the highest mean value was found in (Densah bur) group, while the least mean value was found in (Osteotome) group. Conclusion: Within the limitation of this study, Densah bur can be applied for closed sinus lifting in a simple, safe and predictable way with reduced morbidity without need to hand tapping force.
