Abstract

Development of bioactive materials for the replacement or repair of body tissue is being rapidly developed today. This research aims to develop material of biocomposite hydroxyapatite (HAp) - glass ionomer cement (GIC) for hard tissue restoration. Glass ionomer cement is biocompatibility in nature, that it shows good biological effect on the structure of hard tissues (bones and teeth). Another advantage of this material is that glass ionomer cement is anti-bacterial. In this study, specimens prepared by mixing hydroxyapatite (HAp-200) with glass ionomer cement of GC Fuji IX with composition of 10% of HAp: 90% of GIC, 20% of HAp: 80% of GIC, and 30% of HAp: 70% of GIC, all in% of weight. Hydroxyapatite was mixed with glass ionomer cement (GIC) for approximately 60 minutes to obtain a homogeneous powder mixture. To cause bonding between the particles, the catalyst of GC Fuji IX was added in the amount of 70% wt and stirred thoroughly. The growth of apatite can be seen from the SEM test at 30% of weight of HA200-70% of weight of GIC after soaking in SBF for 28 days. The results showed that the highest hardness value was of 20% of HAp- 80% of GIC, which was 45 VHN.
