Study of hydroxyapatite based on Aceh's bovine bone coating on 314L stainless steel as a candidate for coating dental implant materials

Abstract

ABSTRACT The use of hydroxyapatite (HAp) based on Aceh's bovine bone has been studied as a candidate for the
coating dental implant materials. In this study, the effect of sintering temperature and viscosity on the thickness of
the hydroxyapatite layer on the 316L stainless steel plaque was observed. The hydroxyapatite was synthesized from
bovine bone and then coated on the plate using the dip-coating method. Then, the plate surface was dried at 110 ºC
for 30 minutes and sintered with various temperatures of 500, 600, 700, and 800 ºC for 1 hour. The plate that has
been coated with hydroxyapatite was characterized using a thickness meter to measure the thicknesses of the layer.
The water composition of 10 grams/L had a better effect on the thickness of the implant material coated with HAp
beef bone compared to the water composition of 4, 6, and 8 (gram/L) (p<0.05). On the other hand, the temperature
factor did not affect changes in the thickness of the implant material (p>0.05). The higher water composition (10
grams/L) resulted in a decrease in the thickness of the implant material coated with beef bone HAp.
