Growth, is the main occupation of children to adapts its development structures above others destabilizing factors. By the age of two the average child has spent around 9,500 h dreaming. Between two and five years, a child spends 50% of time asleep. And from childhood to adolescence sleep time accounts for about 40% of child’s day. It’s easy to understand the importance of sleep during growing time. If a destabilizing mechanism appears during this period the result could move away from an harmonious growth pattern. Sleep breathing disorders (SBD) should be considered before planning orthodontic treatment. Maxillary orthodontics increase airway dimensions and reduce the pharyngeal collapsibility. People with SBD will therefore to withstand more adverse conditions during breathing and reduce the risk of suffering these events compared with untreated conditions.
