TULO – An Automated Mandibular Advancement Device for the Treatment of Obstructive Sleep Apnea

Student of Indian Institute of Technology Kanpur, Vimal C won the award for research work of TULO – An Automated Mandibular Advancement Device for the Treatment of Obstructive Sleep Apnea. He carried her project work under guidance of Prof. Dr. J. Ramkumar.

Obstructive sleep apnea is a sleeping disorder that affects about five percent of adults. Sleep apnea is a condition in which the airway in your throat collapses when you sleep, so the muscles relax. If this collapse is constant, it causes apnea or simply said absence of breath. If the collapse is not constant, usually causes snoring. The long term consequences of having obstructive sleep apnea are high blood pressure, sleepiness, headaches and risk of heart attack or stroke. Mandibular advancement devices have mouth guard that is fitted to both top and bottom teeth and joined together in a way that bottom teeth are in front of the top teeth. Pushing the bottom jaw forward opens up and supports the airway, so there is less chance to collapse. Mandibular advancement devices are the oral appliance used to treat snoring and obstructive sleep apnea. These devices protrude the mandible and induce changes in the anterior position of the tongue, soft palate, lateral pharyngeal walls, and mandible, resulting in improved airway patency. Evidence suggests that MAD improves snoring and OSA. Extent of advancement in MAD enhance efficacy in reducing upper airway obstruction events but it also increases temporomandibular joint pain, myofascial pain, occlusal changes and anxiety and stress of the patient. Usage of a MAD device however requires some precision adjustment and frequent visit with the physician thus induces a lot of ambiguity to the user. Hence we have developed an automated MAD device in two specific advancement platforms. One is a time dependent mandibular advancement while the other is advancement of the mandible with respect to oxygen desaturation levels in the body through a wearable band.
