A patient wearing a removable appliance should be reviewed every 2-4 weeks to ensure proper appliance function, monitor oral hygiene, and assess tissue response. Regular reviews allow timely adjustments to maintain correct force application, preventing undesired tooth movement or tissue irritation. Early detection of appliance damage or loss improves treatment efficiency and patient compliance. Longer intervals risk treatment delays and complications, while shorter intervals are unnecessary if no issues arise. This review frequency optimizes treatment outcomes and patient safety.
