Custom 3D-Printed plate shows promise for jaw fracture repair
NCT ID NCT07206134
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This study tested a new custom-designed omega-shaped bone plate against standard metal plates for fixing broken jaws in the chin area. Twelve adults with such fractures were split into two groups, one receiving the custom plate and the other the standard one. The custom plates were made using virtual surgery planning and 3D printing. Researchers checked healing, pain, swelling, and nerve function over six months to see if the new plate works better.
