title: [Demineralized and freeze-dried human bone allografts in the treatment of periodontal osseous defects].
abstract: Demineralized and freeze-dried human allografts were implanted into 39 bony defects of 37 teeth in 26 cases. After 3-45 months, the total rate of efficacy was 82.05%. There was no significant difference between the two implanted materials. It was further proved that three walled infrabony defects or angular bone destructions in radiographs were most indicated for implantation, and the efficacy of implants had no relationship with the pocket depth.
