Abstract
Abstract
Purpose
To evaluate the efficacy of using Densah burs in lifting the maxillary sinus membrane in cases with an oblique sinus floor with a residual bone height (RBH) of 4–7 mm.
Methods
The study was conducted on 16 patients (9 males and 7 females, ages 25–60 years). Sinus floor elevation was achieved using Densah burs utilizing the osseodensification concept (OD), with dental implants placed simultaneously. The sinus membrane integrity was checked clinically and confirmed with cone beam computed tomography (CBCT).
Results
Out of 16 cases, 1 case exhibited sinus membrane perforation confirmed clinically at the time of operation. A mean lift of 4.42 mm was achieved in all cases. A mean final seating torque of 35.5 N/cm was achieved for all implants. At the one-year follow-up, all cases exhibited clinical success with no signs of sinus pathology or complications.
Conclusion
In moderately atrophic posterior maxilla with a RBH 4–7 mm, OD proved to be a safe and effective method in performing sinus lift procedures in cases with oblique sinus floors.
