Purpose/Objectives:
The aim of this study was to evaluate whether 3D-printed models can be an inexpensive and suitable way to train dental students to perform a sinus lift.
Methods:
The sinus lift model was created using CAD/CAM technology. Approximately one year prior to their final examination, thirty-one dental students evaluated and tested the sinus lift simulation model and two different techniques of sinus lift. Their experiences were assessed using a questionnaire. Statistical analysis was carried out by Wilcoxon rank sum tests.
Results:
The sinus lift procedure was easy to understand and perform using the material. The two procedures (rotary instruments vs. piezosurgery) were evaluated equally by the students. Only the gingiva mask was criticized.
Conclusions:
3D-printed maxillary models provide a reproducible alternative to conventional typodonts, enabling curriculum-specific training in sinus lift procedures. While the models were rated positively for structural realism and educational value, soft tissue components require further refinement to enhance simulation fidelity.
