Split-Mouth Comparison of Invisalign Attachments
United States30 participantsStarted 2025-11-20
Plain-language summary
This study evaluates how accurately the attachments used in Invisalign treatment (Align Technology Inc., San Jose, CA, USA) match their planned shapes and sizes in the ClinCheck software (ClinCheck®, Align Technology Inc., San Jose, CA, USA). Attachments are small tooth-colored bumps that help clear aligners grip the teeth and move them effectively.
The investigators are comparing two types of attachments: optimized and conventional, to determine which is bonded to the tooth more accurately and maintains its shape better over time. Participants beginning Invisalign treatment will have attachments placed as part of their normal care. Digital scans will be taken immediately after placement and during follow-up visits to assess attachment accuracy and wear.
The goal is to identify which attachment design provides greater precision and durability to improve the predictability and efficiency of Invisalign treatment planning.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adults aged18 years or older.
* Patients initiating Invisalign treatment with planned composite attachments.
* Ability to provide written informed consent and agree to additional research intra-oral scans.
* Good oral hygiene and absence of active periodontal disease at enrollment.
Exclusion Criteria:
* Extensive dental restorations (composites, crowns, veneers) on study teeth that could interfere with attachment bonding.
* Enamel defects or severe wear on study tooth surfaces affecting bonding accuracy.
* Contraindications to digital intraoral scanning (e.g., severe gag reflex, metallic prostheses preventing accurate imaging).
* Severe tooth malposition that would compromise accurate attachment placement.
* Poor oral hygiene or active periodontal disease at enrollment and/or if the patient develops poor oral hygiene or active periodontal disease during treatment.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
