Design outcomes

Primary

Measure	Time frame
Does training the BSSO with a 3D-printed model lead to an improvement of surgical skills on a Global Rating Scale? (Measurement time point: after both runs based on video recording of the work area)	—

Secondary

Measure	Time frame
-What is the minimum distance in mm between the fracture gap and the inferior alveolar nerve on the 3D-printed model of the BSSO? -How often does a bad split (unfavourable fracture of the mandible) occur on the 3D-printed BSSO? -Does performing a BSSO on a realistic 3D-printed model 3D-printed model improves the understanding of this using a numerical rating scale (NRS)? -How is the model perceived visually, haptically and as practical, in terms of in relation to the preparation for an upcoming operation in terms of Likert questions? -Are there differences between students and doctors/dentists with regard to questions regarding the outcomes?	—
