A clinical and radiographic case series of implants placed with the simplified minimally invasive antral membrane elevation technique in the posterior maxilla.

The aim of the present case series was to evaluate a simplified minimally invasive transalveolar sinus elevation technique utilizing calcium phosphosilicate (CPS) putty for hydraulic sinus membrane elevation. The simplified minimally invasive antral membrane elevation technique is based on the application of hydraulic pressure via a viscous bone graft that acts as an incompressible fluid. In this retrospective study, 21 patients (mean age: 48.
