AbstractBackground

Little is known about the long‐term outcome of implants placed in the atrophic maxilla using osteotome sinus floor elevation (OSFE) without grafting.

Purpose

The study aims to evaluate the long‐term efficiency of the procedure and stability of the peri‐implant bone formed following implant placement without grafting into resorbed posterior maxilla.

Materials and Methods

Twenty‐five implants (≤10 mm in length) were placed in 17 patients using OSFE without grafting. The mean residual bone height was 5.4 ± 2.3 mm. Bone levels were evaluated at 1, 3, 5, and 10 years using periapical radiographs.

Results

Fifteen patients (23 implants) participated in the 10‐year examination. All implants fulfilled the survival criteria. Following surgery, the implant sites gained endo‐sinus bone (mean: 3.0 ± 1.4 mm). The mean crestal bone loss (CBL) was limited to 1.0 ± 0.9 mm. The difference in mean endo‐sinus bone gain and CBL was statistically significant between 1 and 10 years, but not between 3 and 5, 3 and 10, and 5 and 10 years.

Conclusions

At 10 years, the implant survival rate was 100%. Endo‐sinus bone was mainly gained during the first year. This study demonstrates the long‐term predictability of OSFE without grafting and simultaneous implant placement.
