3D-Printed jaw models help surgeons rebuild faces more accurately

This study tested two ways of using 3D-printed models to help rebuild the lower jaw after tumor removal. Surgeons used bone from the patient's leg to replace the missing jaw section. One method used a full model of the healthy jaw, while the other used a segmented model that fit the leg bone pieces precisely. Both methods worked, but the segmented model gave more consistent facial symmetry. The study involved 36 people and was completed at Indonesia University.
