The influence of crossbite in early development of mandibular bone asymmetries in paediatric patients

BACKGROUND All authors agree that posterior crossbite is a malocclusion that affects mandibular growth and may lead to skeletal asymmetry but there are few data on which age these modifications are easily quantifiable.
