Test-retest and accuracy of measuring the position and orientation of the human mandible via magnetic sensors: A pilot study

摘要: Obstructive sleep apnea is a common type of sleep-disordered breathing, often treated with an oral appliance that protrudes the mandible. This therapy widens upper airway thereby eliminating and/or preventing collapses obstructions during sleep. Up till now, monitoring actual position mandible was not available — although this should be considered prerequisite in process judging treatment efficacy thus impeding compliance monitoring. To optimize therapy, patient-based data need to collected device's use. At present, electronic sensors attached temperature cavity are used objectify as simple time-logged binary signal: wearing-not wearing. The current paper presents in-vitro set-up for both and protrusion relative jaw. Two magnetic maxillary part combination two magnets affixed lower appliance. mandibular maxilla measured accuracy 0.5 mm range 17.5 protruding direction.
