Pembuatan Prototipe Replika Tulang Berbasis Hidroksiapatit Menggunakan Metode Starch Consolidation

---

3D bone replica based on porous Hydroxyapatite (HA) is a candidate bone implant material that has similarities to the original bone. One technique for fabricated porous HA is the starch consolidation method. The objective of this study was to determine the effect of starch addition and starch types on porous HA. The study was conducted by mixed HA as much as 20 grams with the amount of starch 8, 10, 12 and 14 grams in the form of sago starch and corn starch, and 25 ml of distilled water to form a slurry. The slurry formed is then stirred at 400 rpm. The mixture is then poured into a mould. Then the mixture in the mould was heated to 100oC for 60 minutes. After that, the green bodies are removed from the mould and dried in an oven at 80°C for 24 hours and 110°C for 8 hours. The dried sample is then put into the furnace. Combustion is carried out at a temperature of 600˚C and ended with sintering at a temperature of 1250˚C each for 1 hour. Porous HA using corn starch has higher bending strength compared to porous HA using sago starch. Increasing the addition of starch causes the greater porosity and shringkage, the density and the bending strength is getting smaller. Sintered bodies show shrinkage in the range of 34.24–48.26%, porosity 22.0-40.1%, density 1.89-2.46 gr / cm3, bending strength 0.33-2.33 MPa and pores size obtained is in the range of 80-250 μm.
