Design outcomes

Primary

Measure	Time frame
1. Difference in haptic properties during osteotomy between the different printing materials compared to a pig rib measured using NRS .	—

Secondary

Measure	Time frame
2. Difference in NRS evaluation between the two cohorts regarding the comparability of the osteotomy behaviour of the 3D-printed models with the real pig rib. 3. Blinded evaluation of the models by two examiners with regard to fusion, string formation and fraying using a Likert scale. 4. Comparison of the duration of the osteotomies as a function of the models used and osteotomy technique to the pig rib. 5. Evaluation of the bending properties of the 3D-printed models considering different printing parameters in comparison to the natural pig rib using a 3-point bending test.	—
