Are aligners effective and efficient in growing patients?

Background: Proper development of deciduous and mixed dentition is essential to the oral health of growing patients, and early interceptive orthopedic or orthodontic treatments are indicated in specific clinical situations. Nowadays, orthodontists are subjected to a lot of pressure from growing patients and their parents about the orthodontic appliances that should be used. The aim of this article is to indicate how, when and why it is possible to effectively use aligners in growing patients.

Case report: Two case reports are illustrated, one with a Cl.II subdivision, mono lateral cross-bite and vertical growth, and the other with a skeletal and dental Cl.II, vertical skeletal pattern, proclined and fractured upper incisors. The efficacy/efficiency ratio of aligners is analyzed in order to evaluate the suitability of this appliance for the treatment. Limits and advantages of aligners are widely discussed.

Conclusion: Aligner treatment in growing patients shall be carefully studied to reach an optimal result. At present, a hybrid treatment strategy represents the best solution in growing patients with a complex clinical situation.
