Composite-resin attachments can be added to improve tray retention or apply force in directions that a tray cannot achieve by gripping tooth surfaces alone.
What is the practical comparison point for Invisalign?
For any clear-aligner plan, compare how the trays create corrective force, how long they are worn each day, and whether attachments are needed for movements the trays cannot make by gripping teeth alone.
ClearCorrect treatment can include sequential trays, composite-resin attachments placed with engager templates, and retainers used to help prevent relapse after active tooth movement.
ClearCorrect retainers are clear thermoformed appliances intended to prevent teeth from relapsing after aligner treatment. They are typically prescribed at the end of treatment and can also be prescribed if treatment is interrupted.
When is a retainer more relevant than another active tray?
A retainer is used to keep teeth from moving back after active aligner treatment, rather than to continue planned tooth movement. It can be prescribed after treatment or when treatment is interrupted.
Compare the planned tooth positions, daily wear commitment, each tray's one-to-three-week interval, and whether attachments are needed to create the required direction of force.
