In this case report a partially edentulous 54 years old, non-smoker and female patient with bilateral atrophic posterior maxilla ranging from 1 to 10 mm residual bone height below the sinus cavity, has been treated performing minimally invasive surgery under a certain new protocol with simultaneous placement of implants. Contrast to traditional utilization of Sinus Floor Elevation (Crestal or Lateral approach without perforating the Schneiderian membrane), this innovative protocol - named “IPG-DET Technique” - introduces the sinus membrane intentional perforation as an alternative. The intentional perforation (flapless or not) combined with an autologous biomaterial (CGF-CD34+Matrix), an alloplastic bone grafting material followed by immediate implantation into the sinus has been proven a safe and stable solution with long-term prognosis. A pair of Cone Beam Computed Tomography images taken before and with (8) months post-surgery has shown significant new bone formation around the implants placed with the “IPG-DET Technique”. The proposed method results simple, safe, less painful and cost-effective solution that may change completely the conventional treatment plan and strategy for the exact position and the procedure used to place implants in the posterior region of the maxilla, especially in cases of severe atrophy and sinus pneumatization.
