Customized 3D-printed models for training in repairing large maxillary sinus membrane perforations.

Area of Science:

• Dental Surgery
• Medical Simulation
• 3D Printing Technology

Background:

• Maxillary sinus membrane perforation is a complex complication during dental procedures.
• Standardized training for repairing large perforations is lacking.
• Existing training methods may not accurately replicate clinical scenarios.

Purpose of the Study:

• To design and fabricate a personalized 3D-printed model for training large maxillary sinus membrane perforation repair.
• To evaluate the training efficacy and cost-effectiveness of this novel simulation model.
• To provide an efficient and standardized training solution for complex maxillary sinus-related surgical procedures.

Main Methods:

• Customized 3D models were fabricated using CBCT and intraoral scan data with tissue-mimicking materials.
• Twenty dentists with limited experience in sinus membrane repair underwent simulated surgery on the models.
• Training outcomes were assessed via pre- and post-training questionnaires, and cost-effectiveness was evaluated.

Main Results:

• Significant improvement in participants' post-training scores (p < 0.001).
• The 3D-printed model accurately simulated large maxillary sinus membrane perforations, aiding rapid skill acquisition.
• Training 20 participants cost $315, demonstrating significant economic advantage over traditional methods.

Conclusions:

• The personalized 3D-printed model offers high fidelity simulation for complex maxillary sinus perforation repair.
• It serves as a safe, efficient, and cost-effective hands-on training platform for clinicians.
• This innovative tool can improve clinical repair and bone grafting success rates in dental practice.
