Abstract
The use of finite element modeling (FEM) to analyze root stress patterns during extrusion and intrusion movements using clear aligners is gaining momentum. The results showed that extrusion movements generated higher root stress compared to intrusion, with variations observed across different tooth types. The study provided insights into the potential risks of root resorption during aligner therapy, emphasizing the importance of controlled movement. This can help clinicians optimize treatment plans to minimize adverse effects on tooth roots. However, more data is needed to explore the long-term implications of aligner treatments on root health.
