Background: Dental implantology is considered as the most widely treatment employed in edentulous patients. So far, cases with vertical alveolar ridge deficiencies of the posterior areas of the upper jaw are treated primarily with sinus floor elevation in order to achieve successful and stable dental implantation.

Method: Employment of the “IPG” DET technique for the placement of forty-eight (48) implants in the posterior areas of the maxilla of twenty-seven (27) patients. Implant placement was made by means of a flapless approach – in which implants are entered both the sinus cavities – by intentional perforation of the Schneiderian membrane. Concentrated growth factors, as well as Alos-Block bone grafting material – were also utilized in this study, following a certain and precise protocol suggested by the authors.

Results: Cone Beam Computed Tomography exams were employed at two distinct temporal stages of Osseo-integration (0 and 8 months) and have proven the increment and bone structure growth formed bilaterally each implant and over the sinus floor. In addition, the primary stability of all implants was estimated with Implant Stability Quotient parameter showing high values that are suggestive of high implant stability.

Conclusions: Radiographic and clinical data support the concept of a one-step atraumatic procedure in implant placement with intentional perforation of the sinus membrane when there is ridge deficiency by means of the proposed technique.
