Subjective versus objective dental side effects from oral sleep apnea appliances

• Purpose: Occlusal changes are common during long-term treatment with oral appliances (OAs) for sleep apnea. The aim of the present study was to compare subjectively reported bite changes with objective findings.Methods: Consecutive adherent treated patients were asked to participate in this study. The patients responded to two questionnaires using numeric visual analogue scales (VAS), ranging from 0 (not at all) to 10 (very much). The first questionnaire included open questions and the second questionnaire comprised specific questions about side effects. Measurements of overjet, overbite, and space for the teeth were made on plaster casts taken before treatment start and at follow-up.Results: Thirty-eight (12 women) patients with a median age of 64 years (interquartile range (IQR) 57 to 69 years) and a median treatment time of 9.5 years (IQR 5.8 to 14.3 years) were included. Overjet, overbite, the molar relationship, and the irregularity of the lower front teeth had changed significantly during treatment. There were no associations between any of the patients’ responses and the objectively measured bite changes. Younger patients, those with a small baseline overjet or overbite and those who developed an anterior crossbite were more likely to report bite changes.Conclusions: Patients who choose to continue long-term treatment with oral appliances for sleep apnea are unaware of various types of bite changes. Such changes will, however, progressively increase in magnitude and be more difficult to take care of, if needed. It is therefore important continuously to follow up patients in regard to bite changes.
