Abstract

Nowadays it is possible to perform an optimal implant placement and to achieve a good long-term prognosis for an implant-borne prosthesis in the grafted posterior maxilla. This study evaluates the efficiency of one-stage piezosurgery by using as graft material a combination of particulate bovine bone substitutes with platelet-rich fibrin to achieve sinus lift. We included in this study 14 cases of one-stage sinus lift surgeries during which we placed 30 standard implants. The mean vertical bone height gain was 10.12 mm six months after surgery, and the mean postoperative follow-up time was 43.79 months. There were no major complications during or after surgery, and all implants are in use. Therefore, it can be concluded that one-stage sinus piezosurgery using particulate bovine bone substitutes and platelet-rich fibrin can be applied as a predictable and effective technique in the treatment of the posterior edentulous maxilla ensuring 4-5 mm vertical bone height.

Highlights

Maxillary sinus floor augmentation is a surgical procedure, which increases the amount of bone in the posterior maxilla by the elevation of the sinus (Schneiderian) membrane from the underlying sinus wall and by placing a bone graft under it
Maxillary sinus augmentation is a welldocumented surgery with long-term clinical success/survival of the implants similar to those placed in the pristine bone [1,2,3]
According to Kendrick DE 2016 [15], two-stage lateral sinus augmentation is indicated when the crestal bone is less than 3 mm high, one-stage lateral approach when we have 34 mm bone height available, and one-stage crestal approach when bone height is above 4-5 mm

Summary

Introduction

Maxillary sinus floor augmentation ( known as sinus lift, sinus graft, sinus augmentation, or sinus procedure) is a surgical procedure, which increases the amount of bone in the posterior maxilla by the elevation of the sinus (Schneiderian) membrane from the underlying sinus wall and by placing a bone graft under it. The aim of sinus augmentation is to obtain bone to support a dental implant. Since 1974 when the first surgery of sinus lift was performed, the science of biomaterials has improved by enhancing the possibilities of graft augmentation and allowing clinicians to perform implant-borne dental restorations in complex situations. It is possible to perform an optimal implant placement and to achieve a good long-term prognosis for an implant-borne prosthesis in the posterior grafted maxilla. Maxillary sinus augmentation is a welldocumented surgery with long-term clinical success/survival of the implants similar to those placed in the pristine bone [1,2,3]
