Abstract Introduction This study aimed to validate a three‐dimensional (3D) printed model provide training for supernumerary teeth (SNTs) extraction. Materials and Methods Each of the 30 participants, grouped as experienced without experience, conducted two identically simulated surgeries on 3D‐printed replica human mixed dentition with SNT. The surgery time, area bony window volume removed material were measured; subsequently, responses five‐item questionnaire recorded. collected data statistically analysed. Results time was 228.37 ± 141.53 seconds 125.47 53.03 in first second surgery, respectively. significantly decreased participants experience ( P = .000). However, there no significant differences opening .271) between .075). who perceived educational benefits accounted more than 60% respondents every question. Participants SNT extraction showed tendency rate higher score did those experience. Conclusions A surgical can improve skill and, especially, shorten learning curve beginners.
