Upper Airway's Pressure Drop Analyses After Mandibular Advancement and Maxillary Expansion
Breathing is a crucial function for everyone. Breathing impairment in children could lead to behavioral and cognitive problems at least. But what if orthodontic treatment could help those patients to breathe better, with less effort? This research proposal aims to find out if the increase in the upper airway volume see

| Summary | Breathing is a crucial function for everyone. Breathing impairment in children could lead to behavioral and cognitive problems at least. But what if orthodontic treatment could help those patients to breathe better, with less effort? This research proposal aims to find out if the increase in the upper airway volume seen in some research results can be related to a decrease in respiratory effort and an improvement in the breathing capacity of those patients. In other words, if a tube shape is changed or if a tube is enlarged, would the airflow passing inside the tube change in velocity? Or would there be more air? Therefore, investigating the pressure/airflow, volume/lumen relation and its possible changes after mandibular repositioning and maxillary expansion in children will lead to a bet |
