PROMOTION OF OSTEOGENESIS BY A PIEZOELECTRIC BIOLOGICAL CERAMIC

Hydroxyapatite (HA) ceramic and piezoelectric biological ceramic, hydr oxyapatite and barium titanate (HABT), were implanted in the jawbones of dogs. Histological observation showed that, compared with HA cerami cs, HABT promoted the growth and repair of the bone significantly, the tissue growth around the HABT ceramic was direction-dependent, the co llagen arranged orderly and the bone grew orderly. The order growth of the bone increased the efficiency of osteogenesis on the surface of t he implanted HABT ceramics. (C) 1997 Elsevier Science Limited. All rig hts reserved.
