The Effect of Tooth Position During Orthodontic Treatment on the Apnea/ Hypopnea Index (AHI)


The study design of this research project involves orthodontic patients registered at the Harvard School of Dental Medicine who are deemed eligible to undergo orthodontic treatment and who have been provided with sufficient information to make informed consent to join the sleep study. These patients will be provided with the Medibyte sleep monitor and instructed on the proper manner in which it should be set up and worn for the one night study period. This process will be carried out twice throughout the course of the study, once before any orthodontic appliance has been cemented and once after the required amount of tooth movement has been attained with the orthodontic appliance still in place. The de-identified data from the Medibyte monitor will be downloaded using the Braebon software and analyzed.
