Abstract

Objective: To determine the bone height gain (BHG) achieved after sinus floor elevation (SFE) with osseodensification (OD).

Materials and methods: Patients from an implantology learning center presenting one missing teeth in the posterior maxilla and insufficient residual bone height (RBH) were included. SFE with simultaneous implant placement was performed using Densah drills. Demineralized bovine bone mineral, hydroxyapatite+β-TCP, calcium phosphosilicate, and autologous leukoplakelet fibrin were used as graft biomaterials. BHG was obtained by subtracting the implant length from the initial bone height.

Results: Sinus membrane perforation occurred in 4.8% of 144 cases. One hundred and thirty-seven patients were analyzed for BHG. RBH equaled 5.4 ± 1.8 mm, with 42 (30.7%) cases having < 5 mm. The average implant length (AIL) was 8.8 ± 1.1 mm, resulting in a mean BHG of 3.4 ± 1.7 mm. BHG was significantly higher in cases with RBH < 5 mm (5.23 ± 1.45 mm) than ≥ 5 mm (2.62 ± 1.15 mm) (p < 0.001). Greater gains were observed in first molars (3.70 ± 1.72). Implant brand and graft type did not influence BHG. The survival rate of the implants reached 97% after 6 months of osseointegration.

Conclusions: OD with simultaneous implant placement was effective for SFE, applying a variety of implant brands and type of bone substitute, resulting in clinically relevant BHG, adequate AIL, and low complication rates.
