JIMENEZ GUERRA, A. et al. Sinus floor augmentation in the treatment with dental implants: a 4-year study. Avances en Periodoncia [online]. 2015, vol.27, n.3, pp.145-154. ISSN 2340-3209.

Introduction: The aim of this study was to report the outcomes of sinus augmentation with a biomaterial in implant therapy of posterior maxilla. Methods: 70 partial edentulous patients were treated with 181 Galimplant^® sandblasted-etched surface implants for rehabilitation of posterior maxilla by sinus floor augmentation with betatricalcium phosphate (Osteoblast^®). Implants were loaded after a healing free-loading period of 6-8 months. Results: Clinical results indicate a survival and success rate of implants of 98,4%. 3 implants were lost during the healing period. 85,1% of implants were inserted simultaneously following the sinus floor elevation. After a mean functioning period of 57.4 months, no late complications were reported. Implants were restored with single crowns (22.4%) and fixed bridges (77.6%). Conclusions: This study indicate that rehabilitation of posterior maxilla with implant therapy by sinus floor augmentation technique constitute a successful dental treatment.
