title: Maxillary sinus elevation for implant placement using calcium sulfate with and without DFDBA: six cases.
abstract: Maxillary sinus lift is a surgical procedure performed to increase the volume of bone mass so that dental implants can be placed in the maxillary arch. Several materials have been suggested to be used for this procedure. The purpose of this study was to present the clinical and histologic results of using calcium sulfate with and without demineralized freeze-dried bone allograft (DFDBA) in sinus lift. Medical-grade sterile calcium sulfate was used alone or in combination with DFDBA in 6 patients undergoing sinus lift surgery for implant placement. Bone biopsies were taken at different times ranging from 6 to 24 months. All samples examined showed bone growth with some possible remnants of the grafted DFDBA. Implants were inserted either at the time of the lift or 6 months later. All of them were secure with primary stability. The cases reported indicate that calcium sulfate can be successfully used alone or in combination with DFDBA for sinus lift procedures and that possible residues of DFDBA can be found within newly generated bone.
