Clear aligners
transparent dental braces
Clear aligners are orthodontic devices that are a transparent, plastic form of dental braces used to adjust teeth.
Clear aligners have undergone changes, making assessment of effectiveness difficult. A 2014 systematic review concluded that published studies were of insufficient quality to determine effectiveness. Experience suggests they are effective for moderate crowding of the front teeth, but less effective than conventional braces for several other issues and are not recommended for children. In particular they are indicated for "mild to moderate crowding (1–6 mm) and mild to moderate spacing (1–6 mm)", in cases where there are no discrepancies of the jawbone. They are also indicated for patients who have experienced a relapse after fixed orthodontic treatment.
Clear-aligner treatment involves an orthodontist or dentist, or with home-based systems, the person themselves, taking a mold of the patient's teeth, which is used to create a digital tooth scan. The computerized model suggests stages between the current and desired teeth positions, and aligners are created for each stage. Each aligner is worn for 22 hours a day for one or two weeks. These slowly move the teeth into the position agreed between the orthodontist or dentist and the patient.

Why this record matters
“Clear aligners” is worth following because a concise public description often conceals a longer documentary argument. Here, Clear, aligners and transparent provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q593903. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2014.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
