SCAFFOLD DARI BOVINE HYDROXYAPATITE DENGAN POLY VYNIALCHOHOL COATING

Abstract

In Indonesia, it is about 40% patients with hard tissue defect due to ostheoporosis, cancer or accidents and the
rest are defect since they have born.For many years, efforts for recovering have been done by transplantation or
implantation methods.Transplantation is more appropriate butit is not sustain because of limited donor, while
implantation using synthetic materials such as bioceramics scaffoldis expensive due to import and the scaffold is
easier to break which does not match to the medical requirements.The research therefore has been addressed to this
issue. Local bovine hydroxyapatite (bHA)scaffold has been used as thebase material and poly vynilalchohol (PVA)
as a coating material.The bHA scaffold was prepared by cutting a fresh bovine bone in the size of 5mmx5mmx5mm
and boil it in a distilled water to remove its organic material. It was then heated up at 900 oC for 2 hours in
furnace to obtain bovine hydroxyapatite scaffold (bHA). Coating process has been carried out by dip coating of the
bHAscaffold in PVA solution.
