Objectives : Patient-specific simulation models are emerging as valuable tools for surgical training.The aim of this study was to describe a novel workflow for the fabrication of patientspecif ic 3D-printed jaw models and to assess their applicability for simulation-based training in oral surgery.Methods : A novel workflow was developed to fabricate patientspecific maxillary models derived from patients' CBCT and intraoral scans.Models' face and content validity were evaluated by 18 periodontists and 50 dental students using a questionnaire with a visual analogue scale (VAS).To assess the impact of simulation training on surgical performance, periodontics residents performed guided bone regeneration procedures either with or without prior simulation surgeries.Each resident completed three independent surgeries in the following order: Surgery 1: without simulation, Surgery 2: with simulation, and Surgery 3: without simulation.Surgical performance was video-recorded and then evaluated by two expert evaluators using de-identified recordings and an Objective Structured Assessment of Technical Skill (OSATS) checklist.Preoperative anxiety was measured using the anxiety (STAI-S) questionnaire.Results : The fabricated model demonstrated high accuracy in replicating the patient's soft and hard tissue anatomy.The mean overall VAS rating score of the model was significantly higher for students than periodontists (83.7 9.7 vs. 72.1 15.8; p < 0.05).The OSATS global rating score results showed a slight upward shift in score distribution from Surgery 1 to Surgery 2, with more consistent performance among residents in Surgery 3.However, these differences were not statistically significant.A trend toward reduced mean anxiety scores was noted in Surgery 2, although this difference also did not reach statistical significance.Conclusions : The proposed 3D-printed simulation workflow yielded accurate and educationally valuable models with the potential to enhance surgical education.Further studies with larger sample sizes are recommended to validate these findings and support their integration into educational curricula.
