The U-Aligner System is indicated for the treatment of tooth malocclusion in patients with permanent dentition (i.e. all second molars). The U-aligner system repositions teeth by way of continuous gentle force.

The U-Aligner system is a series of clear plastic aligners that offer a solution for patients who want an aesthetic orthodontic treatment by utilizing a set of removable aligners to correct tooth malocclusions without the use of conventional wire and bracket orthodontic technology. A dental health professional (e.g. orthodontist or dentist), using a standard personal computer prescribes the U-Aligner system based on an assessment of the patient's teeth, determines a course of treatment with the system, takes molds of the patient's teeth and completes a prescription form. Universal Orthodontic Lab then designs a series of plastic trays intended to gradually realign the patient's teeth in accordance with the physician's prescription using a standard dental software used for tooth alignment (Ortho System™, K180941). The prescribing physician reviews and approves the model scheme before the molds are produced. Once approved, Universal Orthodontic Lab produces trays, which are formed of clear, thin, thermoformed plastic. The trays are sent back to the dental health care professional who then provides them to the patient, confirming fit and design. Over a period, additional trays are provided sequentially to the patient by the dental health professional to gradually move the target teeth to the designed position. The dental care professional monitors treatment from the moment the first aligner is delivered to when the final aligner is delivered. The trays are held in place by pressure and can be removed by the patient at any time. The technology is essentially identical to that used by a number of sequential aligner systems, including the two predicate devices.
