EVALUATION OF HYDROXYAPATITE (HA) FROM WASTE EGGSHELL STRENGTHENED WITH ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE (UHMWPE) BY USING INJECTION MOLDING PROCESS
The Taguchi’s Method has been used as the Design of Experiment (DOE) in order to get suitable parameters for injection molding process when HA/UHMWPE were used as a feedstock and found that the optimized parameter for injection temperature, injection pressure, injection time and holding time were 220˚C, 0.6MPa, 7s and 5s respectively.
The demand for implants in Indonesia is expected to increase to US$ 36.67 million by 2026 at a CAGR of 15.2%. Most of the implants used are Ti6Al4V due to its mechanical properties and biocompatibility. However, these implants do not adhere and can leach aluminum and vanadium ions into the body, which accelerates imp...

A non-uniform distribution of the yttria-stabilized zirconia (YSZ) phase within the HA matrix was shown by microstructural investigations, which affected the mechanical properties of the HA/YSZ composites.
Objective: This study aimed to synthesize hydroxyapatite (HAp) derived from Asian moon scallop (Amusium pleuronectes) shells, characterize its physicochemical properties, and evaluate its biocompatibility when incorporated into an orthodontic adhesive.Materials and Methods: Calcium oxide was obtained by calcining Amusi...

Bone phantom is a testing tool in radiology used to mimic the radiological properties of human bone tissue, with hydroxyapatite (HA) as one of its key mineral components. In this study, HA was synthesized from green mussel shells (Perna viridis) through two different shell preparation methods, namely HA 1 produced by c...
