Objectives: Elevation of the sinus floor with Straumann ® BoneCeramic gave promising results in some recent clinical studies. However, no study has evaluated the long‐term survival of implants after this surgical procedure. We are conducting a prospective, observational study to evaluate the long‐term implant survival after this surgical procedure in clinical practice. We present here an ad‐interim report of this study, including only patients with ≥12‐month follow‐up after implant placement. Methods: This prospective cohort study will last until a follow‐up of 5 years will be achieved in at least 50 patients. Inclusion criteria are: age ≥18 years; presence of a maxillary partial unilateral or bilateral edentulism involving the premolar/molar areas; elective rehabilitation with oral implants; and physical capability to tolerate conventional surgical and restorative procedures. Patients are treated according to the two‐stage technique and the preparation is filled with Straumann ® BoneCeramic. Implant survival is evaluated every 3 months for the first 2 years, and then every 6 months up to 5 years. Results: Fifteen patients are considered in this ad‐interim analysis. Mean follow‐up was 14.9 ± 3.1 (range: 6–18 months). In total, three implants failed, in one single patient, 6 months after insertion. The cumulative implant survival rate was 92.5% (95% confidence interval: 83.0–100%). Conclusions: This ad‐interim analysis suggests that the elevation of the sinus floor with Straumann ® BoneCeramic may be an effective clinical option over >1‐year follow‐up. A longer term follow‐up will allow a deeper characterization of these preliminary findings To cite this article:
