An in vitro bioinspired approach to enhance the bioactivity of titanium implants via electrophoretic deposition and biomimetic mineralization of type i collagen.

Objective: This study aims to explore the efficacy of Electrophoretic Deposition (EPD) for collagen type I coating on titanium implants and its subsequent mineralization to improve osseointegration and bone regeneration.

Methods: Titanium disks were prepared with a sandblasted, large grit and acid-etched (SLA) surface. EPD was employed to deposit collagen type I onto the titanium surfaces, followed by two modes of mineralization: extra-fibril mineralization (EFM) and inter-fibril mineralization (IFM).
