Abstract BACKGROUND: The aim of this study was to measure forces created by progressive mandibular advancement with an oral device, during natural sleep, in a sample of adult patients with obstructive sleep apnea syndrome (OSAS). METHODS: A pressure transducer system was placed on the acrylic arms of a two-piece oral appliance (Herbst type) used by nine moderate to severe OSAS patients, in addition to all captors routinely used for polysomnography. Strains on the left and right sides were collected, during stable sleep stages without arousal, for each step of 1 mm advancement. RESULTS: The mean force in this sample was 1.18 N/mm and showed an almost linear evolution. Measurements showed intra- and inter-individual variability. CONCLUSION: The force values recorded in this study may explain the occlusal and skeletal side effects associated with long-term use of these oral appliances. They illustrate the influence of the extent of mandibular advancement, and indicate a possible dose-dependent effect.
