Area of Science:

  • Dental Education
  • Digital Technology in Dentistry
  • Prosthodontics

Background:

  • Traditional removable partial denture (RPD) design training faces challenges in preparing students for real-world applications.
  • Digital technology offers potential solutions for enhancing RPD design education.
  • Effective RPD framework design is critical for successful treatment of dentition defects.

Purpose of the Study:

  • To evaluate the efficacy of 3D simulation-based preclinical training software for RPDs.
  • To assess the impact of the software on learning outcomes for master's students in stomatology.
  • To gauge user perceptions of the training software among students and faculty.

Main Methods:

  • A 3D simulation software (RTS) was used for preclinical training in RPD design.
  • 26 master's students were randomized into a control group (traditional instruction) and a training group (RTS self-study).
  • Both groups completed theoretical and drawing tests, followed by user experience questionnaires.

Main Results:

  • The training group significantly outperformed the control group in both theoretical (88.8 vs 85.7) and drawing (89.8 vs 85.1) tests.
  • The training group completed the drawing test faster (12.6 vs 17.7 min) but theoretical test completion times were similar.
  • Students and faculty reported generally favorable opinions of the RTS software.

Conclusions:

  • The RTS software effectively improved master's students' understanding and application of RPD framework design principles.
  • The 3D simulation system was positively received by both students and faculty.
  • The RTS enhanced the effectiveness and convenience of dental education for RPD design.
