Summary
Fabricating three-dimensional (3D) tooth models improves endodontic treatment outcomes. Clear resin models excelled in shaping and obturation, while opaque models aided access preparation, enhancing dental education.
Area of Science:
- Dentistry
- Endodontics
- Dental Education
Background:
- Procedural errors in endodontic treatment can be mitigated by utilizing advanced fabrication techniques.
- Three-dimensional (3D) tooth models offer a potential solution for managing complex pulp morphology and dental anomalies.
Purpose of the Study:
- To fabricate 3D resinous tooth models for endodontic treatment.
- To evaluate the efficacy of these models in comparison to natural teeth during root canal procedures.
Main Methods:
- Resinous 3D tooth models were fabricated from natural teeth (1 mandibular canine, 2 maxillary molars).
- 90 natural teeth (30 mandibular canines, 30 mandibular molars, 30 maxillary molars) were used for root canal treatment alongside the models.
Main Results:
- Opaque resin models and natural teeth demonstrated superior performance during access preparation compared to clear resin models.
- Clear resin models significantly outperformed natural teeth and opaque models in shaping, obturation, and educational value.
Conclusions:
- Producing 3D tooth models requires significant time and effort.
- Despite the challenges, 3D tooth models provide more accurate results for evaluating endodontic procedures.
