Unlike palatal expanders or other orthopedic interceptive devices, clear aligners do not act on the bones but only on the teeth. In children, the skeletal structure is still developing, and an effective treatment must take into account bone growth, incorrect oral habits, and mixed dentition (the presence of both baby and permanent teeth).
Using clear aligners during this stage may result in:
- Ineffectiveness in addressing the root causes of malocclusion, which are often skeletal in nature;
- Inadequacy in correcting habits such as mouth breathing or thumb sucking;
- Risk of uncontrolled tooth movement, potentially compromising future bite alignment;
- Difficulty in management, as aligners must be worn consistently (20–22 hours per day), which is not always feasible for a child.
Even the most recent scientific literature confirms that clear aligners are not the first choice in pediatric orthodontic treatments. On the contrary, an early and targeted approach with functional appliances can reduce or even prevent the need for more complex treatments during adolescence.
