Summary

This study tested whether custom 3D-printed plastic (PEEK) plates work better than standard titanium plates for fixing fractures at the angle of the jaw. Twenty-two adults with this type of break were treated and followed to see how well their bite and jaw joint healed. The goal was to find a reliable alternative to metal plates for jaw surgery.
