Abstract:

:

The potential of a bioactive bone cement (BABC) as an onlay graft material for the mandible with and without the periosteum was investigated in rabbits. Its matrix consists of bisphenol--glycidyl methacrylate (Bis-GMA) and triethylene-glycol dimetacrylate (TEGDMA) and its filler is silane-treated CaO–SiO₂–P₂O₅–MgO–CaF₂ glass (A–W glass-ceramic) powder. The BABC was pasted onto the mandible under the periosteum in Group 1, and onto the mandible with the periosteum removed in Group 2 and allowed to set in situ. In both groups, the cement–bone interface was filled by new bone at 4, 12 and 48 weeks, and bone grew from adjacent bone tissue into the cement–soft tissue interface at 12 and 48 weeks. There were no differences in the rate of bone formation between the groups. The shearing strength increased progressively from 0.25±0.10 MPa (mean±SD) at week 1 to 7.98±0.62 MPa at week 48. The results suggest that the BABC has good handling properties, a high bonding strength and good biocompatibility, and that it has potential for clinical application as a substitute material for autogenous bone transplantation.
