Description
Lv and colleagues built a custom 3D-printed training model in 2026 for a delicate dental repair. The repair fixes large tears in the membrane lining the maxillary sinus, the air cavity above the upper jaw. Tears happen often during sinus lift surgery, and large ones are hard to practice on safely. The team printed joined hard and soft tissue models from patient scans, using materials chosen to feel like real bone and membrane.
Twenty dentists with basic experience but no hands-on practice at this repair each performed the simulated operation on the printed models. Their questionnaire scores rose sharply after training, a change the analysis rated as highly significant, and the models copied the look of a real tear left after cyst removal. Training all 20 dentists cost 315 dollars in total, far below traditional training setups, so the authors pitch the model as a cheap, repeatable practice standard.
