Alternatively, attachments may be used to facilitate movement by changing the shape of the tooth. Since the form-fitted plastic used in clear aligners is not as rigid as the metal used in traditional braces, sometimes the flexibility in the materials need to be compensated in the areas that require movement. Patients that need a tooth rotated or pulled down may have a small, tooth-colored composite attachment bonded onto certain teeth. The aligners are made from an elastic thermoplastic material that applies pressure to the teeth to move into the aligner's position. The molds for the aligners are built in layers using a photo-sensitive liquid resin that cures into a hard plastic when exposed to a laser.

The aligners are modeled using CAD-CAM (computer-aided-design and computer-aided-manufacturing) software and manufactured using a rapid prototyping technique called stereolithography. Ī computer graphic representation of the projected teeth movements, created in the software program ClinCheck, is provided to the doctor and patient for approval or modification before aligners are manufactured.

Additional and subsequent rounds of aligners, known as 'Refinements', may be necessary to achieve desired tooth positions as clear aligners do not always achieve full movement in the first round. Anywhere from six to eighty aligners may be needed during the first set of aligners. Technicians move the teeth to the desired location with the program Treat, which creates the stages between the current and desired teeth positions. Dental impressions are scanned in order to create a digital 3D representation of the teeth. The dentist/orthodontist completes a written evaluation that includes diagnosis and treatment plan. The latter method has greatly increased in popularity in recent years as digital scanning technology has improved.

Treatment begins with taking x-ray and photographs for diagnostic purposes, followed by capturing the patient's bite, teeth, and gums via a bite registration and polyvinyl siloxane impressions or an intra-oral digital scanner.

Application 3D representation of a person's teeth in the Invisalign software Ĭlear aligners are more noticeable than lingual braces, but they can be removed, which makes cleaning of the teeth easier, and they are faster for the dentist to apply. A 2013 Cochrane review found no high-quality evidence with respect to the management of the recurrence of lower-front-teeth misalignment following treatment. More cases of relapse of the anterior teeth have been found with clear aligners compared with conventional braces. In those with teeth that are too far forward or backward, or rotated in the socket, the aligners are likely not as effective as conventional braces. Opinion is that they are likely useful for moderate front-teeth crowding. Despite patent infringement litigation, no manufacturer has obtained an injunction against another manufacturer.Ī 2014 systematic review concluded that there is insufficient evidence to determine the effectiveness of these clear aligners. The average treatment time is 13.5 months. These slowly move the teeth into the position agreed between the orthodontist or dentist and the patient. Each aligner is worn for 22 hours a day for one or two weeks. The computerized model suggests stages between the current and desired teeth positions, and aligners are created for each stage. Ĭlear-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. They are also indicated for patients who have experienced a relapse after fixed orthodontic treatment. 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. 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. A 2014 systematic review concluded that published studies were of insufficient quality to determine effectiveness. Ĭlear aligners have undergone changes, making assessment of effectiveness difficult. Clear aligners are orthodontic devices that are a transparent, plastic form of dental braces used to adjust teeth.
