Influence of the Sinus Floor-to-lower Window Margin Distance on Outcomes of Bone Window Repositioning in Lateral Sinus Floor Elevation With Simultaneous Implant Placement

NCT07045389 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 47

Last updated 2025-07-01

No results posted yet for this study

Summary

The goal of this observational study is to evaluate how the vertical distance from the sinus floor to the lower margin of the lateral window affects bone regeneration and implant outcomes after lateral sinus floor elevation with simultaneous implant placement. The main question it aims to answer is:

Does a sinus floor-to-window margin distance ≥3 mm lead to better bone augmentation and implant stability compared to a distance \<3 mm?

This is a retrospective, single-center cohort study. Participants included patients who had previously undergone lateral sinus floor elevation with implant placement and had at least 6 months of postoperative follow-up. Cone-beam CT images were used to measure radiographic outcomes such as alveolar bone height and augmented volume.
