Immediate oral appliances in diagnosis and treatment of obstructive sleep apnea-hypopnea syndrome

Abstract

Abstract: PURPOSES: To investigate the role of immediate oral appliances in diagnosis and treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS). METHODS: Fifty-three patients (45 males, 8 females) with mild, moderate and severe OSAHS confirmed by polysomnogram (PSG) were included in this study. All the patients were evaluated by nasal resistance detection and cephalometric analysis before therapy. Meanwhile, immediate oral appliances were used with the evaluation of PSG. Paired t test and multiple linear regression analysis were carried out using SPSS 17.0 software package. RESULTS: There were significant differences in parameters evaluated between pretreatment and post treatment with immediate oral appliances both subjectively and objectively. It was found that the therapeutic effect of oral appliances had a significant difference with the changes of age, BMI, AHI before treatment, the horizontal distance between the upper and lower incisors wearing oral appliance and distance of overbite (P<0.05). Multiple linear regression equation on the treatment of immediate oral appliances was: =67.956-0.731x₁-1.954x₂+0.411x₃+9.263x₄ (x₁: age, x₂: BMI, x₃: AHI before treatment, x₄: the horizontal distance between the upper and lower incisors), P<0.01, R²=0.472. CONCLUSIONS: Immediate oral appliances could not only predict the therapeutic effect of oral appliances, but also provide support for subsequent treatment.
