Introduction:

Dentofacial disorders in children are associated significantly to respiratory disorders, particularly asthma and allergic rhinitis, and although not pinpointed the mechanism by which impact these pathologies craniofacial development, it is suggested that obstruction upper airway difficult nasal breathing forcing the patient to compensate such obstruction by mouth breathing, this condition being the origin of malocclusion. Objetive: The present study was conducted to determine whether treatment of malocclusion, specifically the correction of transverse compression maxillary positively influences asthma control assessed by clinical evidence of asthma control (Asthma Control Test) and as spirometry (FEV1, FEV1/FVC) at baseline and response tests bronchodilator addition of drug treatment.

Material and methods:

The study just took a group of 15 patients between seven and 12 years of age diagnosed with asthma and allergic rhinitis which were under pharmacological medical treatment for a minimum of six months.

Results:

Among the main results it was observed that there is a significant correlation between the maxillary disjunction and clinical asthma control and lung function in children with asthma and allergic rhinitis, mainly from the third month of orthopedic treatment.

Conclusion:

The use of maxillary circuit breakers, represents an alternative for an adequate management of respiratory disorders manipulating the conditions in the generation processes making the proposed system more efficient.
