Summary
Augmented reality (AR) smartphone apps improve dental bracket placement accuracy for inexperienced dentists. This technology enhances precision without needing radiation or physical guides, aiding clinical practice.
Area of Science:
- Dental technology
- Orthodontic treatment
- Computer-aided design (CAD)
Background:
- Accurate bracket positioning is crucial for successful orthodontic treatment.
- Traditional methods may lack precision, especially for inexperienced practitioners.
- Augmented reality (AR) offers a novel approach to enhance visualization and guidance.
Purpose of the Study:
- To evaluate the effectiveness of AR-assisted software in improving dental bracket positioning accuracy.
- To compare the performance of inexperienced dentists and orthodontists using AR technology.
- To assess the feasibility of smartphone-based AR applications in clinical settings.
Main Methods:
- A comparative workflow was designed to assess bracket placement precision.
- AR-assisted smartphone application used to overlay planned bracket positions onto the clinical crown.
- No 3D radiation imaging or physical guides were required, ensuring safety and convenience.
Main Results:
- Inexperienced dentists demonstrated higher precision than experienced practitioners without AR.
- AR significantly improved bracket positioning accuracy for dentists compared to orthodontists.
- The observed improvement with AR was statistically significant (P < 0.004).
Conclusions:
- AR smartphone applications can enhance the precision and accuracy of dental bracket placement.
- This technology is particularly beneficial for inexperienced dentists, improving their clinical outcomes.
- AR offers a safe, convenient, and effective tool for orthodontic bracket positioning.
