Maxillary sinusfloor elevation and grafting with human demineralized freeze dried bone.
In the continuous search for the ideal grafting material in this study the authors used human demineralized freeze dried bone (DFDB) in the maxillary sinusfloor elevation surgery. In total 30 sinusgrafts were performed in 24 patients. Residual lateral maxillary bone height was less than 8 mm but more than 4 mm. The surgical technique used was according to the description of Tatum (1986). In those 30 grafted sinuses a total of 69 ITI full body screw implants were placed 6 months after grafting. Four sinuses exhibited a prolonged healing time. All implants were loaded 4 months after insertion. No implant losses or failures occurred. The rough surface ITI dental implant appeared to be a suitable implant following sinusgrafting with DFDB. According to the results of this study the limited sinusfloor elevation procedure with DFDB appears to be a clinical reliable pre-implant procedure.
