Simulation training for ceramic crown preparation in the dental setting using a virtual educational system.

Area of Science:

• Dental Education
• Digital Dentistry
• Operative Dentistry

Background:

• Pre-clinical dental training is crucial for developing operative skills.
• Traditional methods may have limitations in providing standardized and objective feedback.
• Virtual reality and simulation offer potential for enhanced learning experiences.

Purpose of the Study:

• To evaluate the effectiveness of a virtual educational system in pre-clinical ceramic crown preparation training.
• To assess the impact of the Virtual Educational System for Dentistry on students' clinical skills acquisition.

Main Methods:

• Fifty-seven dental students underwent virtual ceramic crown preparation training using the Real-time Dental Training and Evaluation System (RDTES) and Virtual Learning Network Platform (VLNP).
• Pre- and post-learning data were collected, and students were grouped based on pre-learning performance.
• Statistical analyses (ANOVA, Kruskal-Wallis, paired t tests, Wilcoxon signed rank tests) were used to compare assessment results.

Main Results:

• Significant improvements were observed in error scores for instrument selection, preparation, reduction, surface, and profile, as well as total outcome assessment scores after virtual learning (P < 0.05).
• Significant interactions between time and student group were found in process and outcome assessments (P < 0.001), excluding 'damage of adjacent teeth'.

Conclusions:

• The Virtual Educational System for Dentistry, integrating VLNP and RDTES, effectively enhances pre-clinical operative training.
• This virtual system demonstrably improves dental students' clinical skills in ceramic crown preparation.
