Development and evaluation of an interdisciplinary teaching model via 3D printing

Area of Science:

• Dental Education
• Biomedical Engineering
• 3D Printing in Dentistry

Background:

• Traditional dental training models often lack realism.
• Interdisciplinary simulation is crucial for comprehensive dental education.
• Advancements in 3D printing offer new possibilities for realistic training tools.

Purpose of the Study:

• To assess the feasibility of a 3D printed interdisciplinary dental training model.
• To simulate endodontic, restorative, and implantologic procedures.
• To evaluate the model's efficacy for dental student training.

Main Methods:

• Utilized Cone Beam Computed Tomography (CBCT) scan data from a patient's mandible.
• Converted DICOM data to STL files for 3D model design.
• Incorporated exchangeable replica teeth, bone segments, and a mannequin head fixation adapter.
• Manufactured the model using 3D printing technology.

Main Results:

• Successfully created a simple, cost-effective, and versatile interdisciplinary training model.
• The model accurately simulates patient anatomy for endodontic, restorative, and implant procedures.
• Dental students found the model comparable to real patient situations for repetitive training.
• The workflow is feasible for creating custom models based on specific curricula.

Conclusions:

• 3D printing and DICOM data facilitate the creation of effective interdisciplinary dental training models.
• This approach supports patient-centered education by offering realistic, repeatable simulations.
• Dental schools can leverage this technology to enhance curriculum and training outcomes.
