| Outline of Final Research Achievements |
We evaluated an appropriate jaw opening by oral appliance for obstructive sleep apnea syndrome (OSAS) patients. Although FIF25-75 increased with jaw opening in both groups，a similar tendency for airway volume was not observed．It is suggested that it is better to decrease unnecessary jaw opening to reduce discomfort for OSAS patients．
We investigated the status of use of oral appliance and following medical consultation (re-evaluation of treatment effect) for OSAS patient. 21 patients were currently using their OAs. Almost patients reported improved subjective symptoms. The most common complication was excessive salivation. The most common reason to quit was “no treatment effect”. Sixteen patients had not undergone re-evaluation after the therapy, and the most common reasons for this were “no treatment effect” and “no time for re-evaluation”. It was necessary to improve device setting and quality to obtain more treatment effects and patients acceptance．
