Description

A 41-year-old male underwent right maxillary bone resection and a dento-maxillary prosthesis was delivered. During maintenance, he was diagnosed with obstructive sleep apnea （OSA）, so an oral appliance （OA） was fabricated and the patient was followed up for two years.<br>The Apnea Hypopnea Index （AHI） without the dento-maxillary prosthesis （WP） was 37.9, with the dento-maxillary prosthesis （P） was 12.2, and with the OA was 1.8. After wearing the OA for two years （OA2）, AHI with OA became 15.4. Sleep stage （N2） WP was 73.0％. OA2 with OA became 62.5％. Sleep efficiency of WP was 66.8％. OA2 with OA became 96.0％. Arousal Index of WP was 18.2. OA2 with OA became 96.0.<br>The results of a sleep test showed that AHI, SpO2min, and sleep efficiency all improved by wearing the OA, and the patient was satisfied with the effects of the OA.<br>When OSA worsens, it is necessary to apply a lower jaw forward traction type OA. We will continue to check oral health and work carefully with medical doctors.
