Abstract: Objectives Elevation of the sinus floor with Straumann (R) 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 (R) 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 (R) 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:Covani U, Orlando B, Giacomelli L, Cornelini R, Barone A.Implant survival after sinus elevation with Straumann (R) BoneCeramic in clinical practice: ad-interim results of a prospective study at a 15-month follow-up.Clin.
