Abstract

This case report aims to inform about the side effects of oral appliances and discuss ways to improve them. The patient is a 68-year-old female with occlusal changes caused by using an oral appliance that does not cover all teeth. She has been treated with an oral appliance for one year to improve her pain in the Temporomandibular Joint (TMJ) area. After treatment, the pain in the TMJ was released, but occlusion changed. Because of her left posterior open bite, she was advised to avoid wearing an oral appliance and to exercise for masticatory muscle strengthening. After one year and six months, occlusal stability improved. It is recommended to wear a complex type of oral appliance that covers all teeth as much as possible only during sleep to avoid side effects.
