Biocompatibility and Chemical Stability

Metal Bone Screws: Long-term implantation may release metal ions such as nickel and chromium, which can cause allergic reactions or inflammation in some patients.

Biodegradable Plastic Bone Screws: They offer exceptional chemical inertness and biological stability.

Benefit: They are non-cytotoxic and non-allergenic, and will not degrade or corrode during long-term exposure to the physiological environment, including body fluids and pH fluctuations.
