Introduction: Dental implants have become more common treatment for replacing missing teeth. Titanium and zirconia have been widely applied as dental implant material because of their excellent biocompatibility and biomechanics properties. However, they are lack of biologically active surface that encourages osseointegration and their mechanical properties significant different from enamel and dentin value. Carbonate apatite Ca10(PO4)x(CO3)y(OH)z comprises a chemical composition closer to bone and enamel. Calcium phosphate are widely used as biomaterials, their osteoconductive and osteoinductive properties have shown beneficial effect on bone osteogenesis. Geopolymers are ceramic-like inorganic polymers, they have excellent mechanical properties, bioactivity, biocompatibility, suitable for hard tissue prostheses, and environmentally friendly. The aim of the study was to evaluate the initial bone healing in geopolymer-carbonated apatite (CHA) nanocomposites. Methods: Geopolymer-CHA nanocomposites samples were prepared in cylinder of 3 mm diameter and 6 mm thickness and placed in the tibia of eight healthy male breeding New Zealand white rabbits weighing 3.0 to 3.5 kg and 6 month aged. Experimental subjects were randomly assigned to 2 groups for evaluating initial bone healing capability around samples to 14 and 28 days histomorphologically. Wilcoxon test was performed and p<0.05 was considered statistically significant, Minitab software version 13 was used. Result:Granulation tissue, woven, and lamellar bone were analyzed. Day 14 revealed a reactive bone formation, which was characterized by granulation tissue, fibroblasts were in an organized extracellular collagen matrix, osteoblast that directly laid out woven bone contained of immature osteoids, and immature osteocytes were observed. The formation of dense fibrocollagen connective tissue that would be the cartilage, osteoblasts, osteoids, and osteocytes showed more mature while woven bone became denser at day 28.Conclusion: Geopolymer-CHA nanocomposites was a potential dental implant material from mechanical and biological properties point of view.Keywords: Histomorphologically, initial bone response, geopolimer-carbonated apatite nanocomposites, dental implant material

“…Geopolymer is an aluminosilicate compound that was formed by the reactions between silica (SiO2) and alumina (Al2O3) in the presence of alkaline activators such as sodium hydroxide (NaOH) and potassium hydroxide (KOH) [4]. Geopolymers have high strength similar to concrete but less CO2 emission in production process.…”

This research studied the engineering properties of hydroxyapatite based on fly ash-geopolymer as a biomaterial. The ratio of Na2O/SiO2 and K2O/SiO2 at 0.15 0.20 0.25 0.30 by mole, 2.5 5.0 7.5, 10 wt.% of calcium phosphate and heat treatment at 500°C, 600°C and 700°C for 2 hours were used to studied changed of compressive strength and crystalline phase in samples. The results observed highest 28-days compressive strength of 21.99 and 19.14 MPa for 0.20 by mole of Na2O/SiO2 and 0.15 by mole of K2O/SiO2, respectively. When calcium phosphate (CP) was added in fly ash-geopolymer, the optimum ratio of CP was found in 2.5 wt.% that have unconfined compressive strength (UCS) of 19.03 and 13.60 MPa for NaOH and KOH activator. After heat treatment of geopolymer at 500°C, the maximum compressive strength at 9.09 MPa and 22.76 MPa for each activator was obtained. Finally, the XRD resulted show hydroxyapatite, mullite quartz and sodium aluminum silicate peaks in both fly ash-geopolymer with NaOH and KOH and 2.5% CP.
