| Abstrak/Abstract | The aim this research is to perform the tensile strength of photo biocomposite materials. This material consist of hydroxyapatite (HA) as a filler, tri [ethylene glycol] dimethacrilate as a matrix, shellac as a coupling agent and camphorquinone as a photoinitiator. Four ingredients then were used to two mixture. The mixture was mixing of TEGDMA and camphorquinone and the second was shellac coated HA. Two of mixtures were mixed to be one solution and was stirred in magnetic stirrer for 1 hour. The solution then was poured into the mold of tensile strength (10 x 10 x 3 mm) and was activated with visible blue light 410-500 nm for 40 seconds in order to be polimerization processes. The irradiation process was done with a maximum thickness 1 mm so that the irradiation process was done 3 times (layer by layer processing). The results of tensile strength test showed that the tensile strength would decrease with the addition of HA or would increase by the addition of TEGDMA. The highest tensile strength was obtained at HA/TEGDMA ratio of 20/80%. This material could be used as a bone substitute materials. |
