Aligner case selection influences treatment predictability, patient compliance, biomechanics, refinements, and long-term orthodontic stabili
Clear aligner success depends heavily on selecting the right cases. Factors such as malocclusion severity, patient compliance, periodontal health, and biomechanical limitations all influence treatment predictability. Mild crowding and spacing cases generally show higher success rates, while deep bites, severe rotations, and skeletal discrepancies often require more complex planning or alternative approaches. Accurate clear aligner treatment planning, combined with realistic patient expectations, helps reduce refinements and improve stability. Modern digital workflows and AI-supported systems continue to improve precision, but clinical judgment remains essential in orthodontic decision-making.
