A Voice in the Arena: From Scans to Simulations

by Chad Foster, DDS, MS, editorial director

Artificial intelligence is already reshaping medicine, and orthodontics could be poised to follow closely behind. In many ways, orthodontics is particularly suited to AI-driven diagnosis and treatment planning because it relies heavily on imaging, measurable anatomical relationships, and predictable biological responses. As AI continues to mature across health care, its influence on orthodontic workflows could be profound.

Currently, orthodontic diagnosis requires synthesizing multiple data sources—clinical examination, photographs, radiographs, digital scans, and cephalometric analysis. AI systems are increasingly capable of processing these datasets rapidly and identifying anatomical landmarks or malocclusion patterns with high accuracy.

In practice, this means that in the future orthodontic consultation may be even more likely to begin with a digital workflow. A patient’s intraoral scan, CBCT imaging, and facial photographs could be analyzed by AI software that instantly generates a preliminary diagnosis and several treatment simulations. Orthodontists would review these AI-generated options and apply clinical judgment to refine the plan.

This concept is already emerging in other medical specialties. In radiology, for example, AI algorithms are routinely used to flag suspicious lesions in mammography or chest imaging before a radiologist even opens the scan. Similarly, dermatology has seen the development of AI systems that can classify skin lesions from photographs with diagnostic performance approaching that of specialists. Orthodontics could adopt a comparable model in which AI acts as an advanced screening and planning assistant.

One of the most promising aspects of AI is its ability to predict outcomes. Machine-learning models can analyze large datasets of past orthodontic cases and learn how teeth typically respond to specific biomechanical forces. These models can then forecast tooth movement, treatment duration, and potential complications, allowing clinicians to design more efficient and individualized treatment plans.

Beyond planning, AI may also influence active treatment. Continuous monitoring tools—such as smartphone-based imaging or remote scanning—could allow AI systems to evaluate tooth movement in real time. If treatment deviates from the predicted path, the software could alert the orthodontist or suggest adjustments to aligners or archwire sequencing.

Despite these advances, AI is unlikely to replace orthodontists. Current research consistently emphasizes that AI performs best as a decision-support tool rather than an autonomous clinician. Human supervision remains essential because orthodontic treatment involves aesthetic judgment, patient preferences, and biological variability that algorithms cannot fully capture.

Ultimately, the orthodontist of the future may function less as a manual analyst and more as a clinical strategist, interpreting AI-generated insights, guiding treatment decisions, and focusing on the patient-centered aspects of care. If integrated thoughtfully, AI has the potential not to replace orthodontists, but to make orthodontic treatment more precise, efficient, and personalized than ever before.
