Despite its advantages, the implementation of AI in orthodontics presents several challenges. The quality and diversity of datasets significantly influence algorithm performance, raising concerns regarding bias and generalizability. Additionally, ethical considerations such as data privacy and informed consent must be addressed.
From a clinical perspective, AI should be considered a decision-support tool rather than a replacement for professional judgment. Current evidence suggests that while AI enhances diagnostic capabilities, clinician oversight remains essential to ensure safe and effective treatment.
✍️ Conclusion
The application of artificial intelligence in orthodontics is redefining clinical workflows by enabling more accurate diagnosis, predictive treatment planning, and personalized care. Although limitations persist, ongoing advancements indicate that AI will play a central role in the future of orthodontic practice.
