Clear aligner therapy (CAT) in two hyperdivergent patients

Patients with the characteristics of hyperdivergent facial patterns (dolichocephaly, shallow overbite and anterior open bites) are generally considered to be challenging to treat as many biomechanical approaches have extrusive side-effects that may lead to further bite opening and exasperate the clinical issues. However, with the increasing numbers of patients undergoing clear aligner therapy, there is a general clinical consensus that clear aligners are a good treatment option for this group of patients as vertical facial dimensions are not significantly affected with treatment. In the absence of literature on this topic, clinical cases are presented to demonstrate successful treatment of dolichocephalic patients with the ClearCorrect clear aligner system. These cases support the general notion that patients with increased facial dimensions can be treated with clear aligner therapy without adverse vertical changes.
