This randomized controlled trial evaluated implant stability and peri-implant bone changes in 60 patients undergoing lateral sinus floor elevation with simultaneous implant placement. The study compared a cylindrical implant with a mild apical taper to a parallel-walled cylindrical implant. The test group exhibited significantly higher primary stability at placement (70.48 ± 8.02 vs. 55.04 ± 12.47, p < 0.001) and a modest difference in stability after 6 months.
Key findings
- The test implant showed higher primary stability at T1 (70.48 ± 8.02 vs. 55.04 ± 12.47, p < 0.001).
- Both groups had increased ISQ values at T2, with the test group at 80.83 ± 3.43 and the control at 78.98 ± 4.18 (p = 0.038).
- All implants had a 100% survival rate without complications.
- No significant differences in endo-sinus bone gain, marginal bone loss, or bone volume changes were observed.
Why it matters
Understanding the differences in implant stability between various systems can guide clinicians in selecting appropriate implants for patients with limited bone volume, particularly in the posterior maxilla.
