New bone formation after a sinus lift procedure using demineralized freeze-dried bone and tricalcium phosphate.

A mixture of demineralized freeze-dried bone and beta-tricalcium phosphate was used for bone augmentation in a sinus lift procedure. Hydroxyapatite-coated implants were placed in the newly formed bone-like material before prosthetic reconstruction. A biopsy specimen taken at 16 months showed that the bone-like material was composed of normal lamellar and woven bone.
