Effective Patient-Dentist Communication with a Simulation System for Orthodontics

Area of Science:

• Dentistry
• Medical Simulation
• Computer-Aided Design

Background:

• Orthodontic treatment is lengthy, costly, and often results in a gap between patient expectations and treatment outcomes.
• Effective communication between orthodontists and patients is crucial for managing expectations and improving satisfaction.
• Current communication methods may not adequately convey the complexities and progression of orthodontic treatment.

Purpose of the Study:

• To propose and evaluate a novel 3D dentist-patient communication system for simulating orthodontic treatment.
• To enhance patient understanding and satisfaction by visualizing the entire treatment process.
• To provide a tool for orthodontists to effectively demonstrate treatment steps and address patient queries.

Main Methods:

• Development of a 3D virtual model system for oral and maxillofacial areas, including face, mouth, and teeth.
• Utilizing clinical case data (before, during, after treatment photos) to tune 3D models.
• Incorporating manual manipulation functions for orthodontists (tooth arrangement, arch-wire placement, facial changes) using 3DS Max.
• Evaluating system effectiveness through patient questionnaires and qualitative interviews with dentists.

Main Results:

• The 3D simulation system effectively visualizes orthodontic treatment processes and simulates clinical paradigms.
• Orthodontists can manually adjust 3D models to demonstrate tooth movement, gum morphing, and facial changes.
• User feedback indicated positive acceptance, usability, and validity of the system for dentist-patient communication.
• The system proved to be an effective tool for improving communication and managing patient expectations.

Conclusions:

• The proposed 3D simulation system significantly enhances communication in orthodontic treatment.
• Visualizing treatment processes improves patient comprehension and satisfaction, bridging the expectation gap.
• This technology offers a valuable tool for orthodontists to explain complex procedures and manage patient expectations effectively.
