Abstract
We have developed a bioactive bone cement consisting of silane‐treated CaOSiO~2~P~2~O~5~CaF~2~ glass powder as the filling particles and bisphenol‐a‐glycidyl methacrylate (BIS‐GMA) diluted with triethylene‐glycol dimethacrylate (TEGDMA) as the organic matrix. Histological examination demonstrated direct bonding between the cement and bone along the circumference of the cement at 4 weeks after implantation in rat tibia. The compressive strength and toughness of the cement were two and four times greater than those of polymethylmethacrylate (PMMA) cement, respectively. The inflammatory reaction of the skin caused by the new cement was not as intense as that for PMMA 3 days after subcutaneous implantation. This new cement may be applicable as a bioactive bone cement with high mechanical strength. © 1993 John Wiley & Sons, Inc.

An affinity quenching method was added as a second filler to a bioactive index was calculated for each cement; this was the length of bone cement consisting of MgO-CaO-SiO 2 -P 2 O 5 -CaF 2 apa-bone directly
We examined the influence of the proportion of glass-ceramic powder in a bioactive bone cement of our formula on the bone-bonding ability of cement. Changes in cement bonding with time also were examined. The bioactive bone cement consisted of MgO-CaO-SiO 2 -P 2 O 5 -CaF 2 glass-ceramic powder (AW-G
The degradation of a new bioactive bone cement (GBC), comprised of an inorganic filler (bioactive MgO-CaO-SiO(2)-P(2)O(5)-CaF(2) glass beads) and an organic matrix [high-molecular-weight polymethyl methacrylate (PMMA)], was evaluated in an in vivo aging test.
