This article describes a technique and reports on the early healing for localized sinus augmentation using a crestal approach in combination with an autologous leukocyte- and platelet-rich fibrin (PRF) concentrate.
From November 2008 to January 2010, 138 implants were placed in 110 patients using osteotome-mediated sinus floor elevation (OMSFE) with PRF.
The mean residual subantral bone height of the alveolar ridge was 6.6 mm (range, 4–8 mm). The mean increase in the height of implant sites by OMSFE/PRF was 3.4 mm (range, 2.5–5 mm). A variety of 8- to 11.5-mm long (mean length, 10.1 mm) and 3.5- to 6-mm wide (mean width, 4.4 mm) screw-type implants were used. Of the 138 implants that had been placed, 97 have been restored and in function for an average loading time of 5.2 months (range, 1–11 months). The mean healing time for the loaded implants was 4 months until abutment insertion (range, 3–5 months). Three implants failed before loading for an early survival rate of both loaded and unloaded implants of 97.8%.
Early review of the OMSFE/PRF technique presented for localized sinus floor elevation and implant placement demonstrates a high degree of safety and success at sites with 5- to 8-mm residual subantral bone height.
