Cosci versus Summers technique for crestal sinus lift: 3-year results from a randomised controlled trial.

Abstract

Both crestal sinus lift techniques produced successful results over a 3-year follow-up period, but the Cosci technique required less surgical time, determined less intra- and postoperative morbidity and was preferred by patients. Conflict of interest statement: This was an investigator-initiated trial, however the trial was partially supported by Zimmer Dental Italy, Vittorio Veneto (TV), Italy. One of the authors (Dr Cosci), who treated 8 patients in this study, is the inventor of the Cosci technique and his partipation was a prerequisite of the sponsor to support the trial.
