3D-Printed vs. machined plates: which fixes jaw breaks better?

This study tested two methods of making custom metal plates to fix broken jawbones. Sixteen patients with fractures between the chin and lower teeth received plates made either by 3D printing (additive) or by computer-controlled machining (subtractive). Researchers measured the plates' strength and how well patients healed. The goal was to find which technique gives better support and recovery for jaw fractures.
