摘要

Background

Mandibular angle fractures are among the most common maxillofacial injuries, and their management via intraoral plating requires high technical precision. Virtual reality (VR)–based simulation has emerged as a promising tool to enhance surgical training. This study aimed to compare the preclinical surgical performance of intraoral mandibular angle fracture plating with and without VR assistance.

Methods

A randomized controlled trial was conducted on 30 participants, including postgraduate residents and assistant professors, divided into two groups: VR-based training (Group A, n = 15) and conventional training (Group B, n = 15). Baseline knowledge was assessed using pre-test scores, while post-training performance was evaluated using the Objective Structured Assessment of Technical Skills (OSATS), procedural time, and participant feedback. Statistical analysis was performed using the Mann–Whitney U test, with p < 0.05 considered significant.

Results

Baseline characteristics and pre-training knowledge scores were comparable between groups (p > 0.05). Post-training knowledge improvement was significantly higher in the VR group (mean score: 18.6 ± 1.5; improvement: +7.2) compared to the conventional group (16.2 ± 1.8; improvement: +5.2; p = 0.002). The VR group demonstrated superior technical performance, with significantly higher total OSATS scores (26.3 ± 2.1 vs. 21.8 ± 2.4; p = 0.001), particularly in screw placement accuracy, plate adaptation, and procedural flow. Additionally, the VR group completed the procedure in significantly less time (28.4 ± 4.2 min vs. 33.6 ± 5.1 min; p = 0.03). Participant feedback revealed higher satisfaction, realism, confidence, and preference for VR-based training (p < 0.05 for all parameters).

Conclusion

VR-based simulation significantly enhances preclinical surgical performance, improving accuracy, efficiency, and learner confidence. Integration of VR into surgical training programs can serve as an effective adjunct to conventional teaching methods, facilitating better skill acquisition in maxillofacial surgery.
