TOPIC: Orthodontic treatment with clear aligners: Possibilities & limitations

Since the establishment of orthodontic specialty, fixed appliances have been the backbone of the biomechanical techniques. However, the unwillingness to wear braces due of their poor esthetic appearance, as well as the new technology advances, especially in 3D imaging and printing, resulted in the development of alternative treatment options, such as the clear aligners.

Treatment with clear aligners is generally indicated for simple to moderate non-skeletal malocclusions and present several advantages, such as ideal aesthetics, ease of use for the patient, and comfort of wear. In addition, the virtual treatment plan can serve as a motivating tool for the patient during consultation.

However, this treatment approach also presents some limitations. Conditions that could be difficult to treat with clear aligners alone include among others, cases requiring teeth extractions, skeletal anterior-posterior discrepancies of more than 2 mm, severely rotated teeth, and teeth with short clinical crowns. Further, the limited control over root movement and the limited intermaxillary correction could be considered as limitations of this approach. Nevertheless, some of these problems may be addressed efficiently if clear aligners are used in combination with temporary anchorage devices, such as the miniscrew implants, to support anchorage during orthodontic tooth movement.

In conclusion, when using clear aligners, achieving similar results to those of the conventional fixed appliances sometimes may be difficult. However, since this approach presents several advantages, it can be efficiently utilized in clinical orthodontics, especially after proper selection of cases and biomechanics.
