The clinical applications of demineralised bone powder (DBP)-induced osteoneogenesis.

New bone tissue can be induced anywhere in the animal organism, i.e. even at a site distant from actual bone, by the implantation of demineralised bone powder (DBP). Basic implantation experiments were first carried out and tested in the rat (Bettex-Galland 1985). The results led us to use the experience gained to treat four patients with bone defects with DBP (one bone cyst, and 3 chronic skull defects). The DBP used was prepared aseptically from fresh cadaver bone. The results were assessed by means of x-ray films and/or CT-scan, and the preliminary evaluation is encouraging.
