New dental implant study tests if plastic or metal frameworks better preserve jawbone

This study compares two types of dental implant frameworks—PEEK (a plastic-like material) and titanium—to see which one causes less bone loss around the implants. Twenty adults with no lower teeth received a fixed set of four implants. Researchers measured bone loss and density at the start and after 3, 6, 9, and 12 months. The goal is to find which material helps keep the jawbone healthier over time.
