This study aims to analyze the effect of collagen in Titanium/carbonate-hydroxyapatite from Pinctada maxima shells successfully applied in Ti substrate using electrophoretic deposition (EPD) techniques. The pretreatment with HCL on the substrate reduced the compressive strength with a porous surface and excellent adhesion during the EPD process. It is proven that Ti/CHA-1, Ti/CHA-3, and Ti/CHA/Coll increase compressive strength. Furthermore, bioactivity in SBF immersion showed apatite growth on the coating surface, increasing the size of the apatite crystals. The effect collagen in Ti/CHA/Coll substrate showed lower crystallinity and mechanical strength compared to Ti/CHA substrates, but the SEM morphology of bioactivity Ti/CHA/Coll significantly showed the apatite growth on the Ti substrate surface. Ti/CHA/Coll showed excellent mechanical properties and bioactivity as a bone graft substitute.
