A new 3D-printed dental model with mobile teeth allows realistic preclinical periodontal splinting training. This inexpensive tool effectively improves student preparedness for clinical procedures.

Area of Science:

  • Dental Education
  • Biomaterials Engineering
  • Periodontology

Background:

  • Preclinical simulation is crucial for dental students to gain proficiency before patient treatment.
  • Developing cost-effective and realistic training models is essential for enhancing dental education.
  • Periodontal splinting requires precise technique, necessitating adequate simulation-based training.

Purpose of the Study:

  • To develop and evaluate a low-cost 3D-printed dental model for periodontal splinting training.
  • To assess learner perception and repositioning accuracy using the 3D-printed model.
  • To compare student preparedness and outcomes using different splinting materials.

Main Methods:

  • A 3D-printed model with repositionable maxillary anterior teeth was utilized for periodontal splinting simulation.

  • Forty-three fourth-year dental students participated in a randomized cross-over study using two splinting materials (polyethylene ribbon and glass-fibre bundle).
  • Learner perception was assessed via an electronic questionnaire, and repositioning accuracy was measured by geometric tooth deviation.

    • Main Results:

    • The training course was rated as good overall and highly clinically relevant by students.
    • Self-reported preparedness for periodontal splinting significantly improved post-training.
    • No statistically significant positional deviations were observed between materials or training sessions.

    Conclusions:

    • The developed 3D-printed model provides a realistic and inexpensive platform for periodontal splinting simulation.
    • This model can enhance structured preparation for clinical teaching and improve student confidence.
    • The simulation effectively trains students in periodontal splinting under simulated tooth mobility conditions.
