Efeitos colaterais do aparelho intraoral de avanço mandibular em pacientes com e sem implantes osseointegrados

Abstract

INTRODUCTION: Mandibular advancement appliances (MAD) are effective for the treatment of Obstructive Sleep Apnea (OSA), however dental and skeletal side effects are limiting factors for treatment. OBJECTIVE: To evaluate the effectiveness of MAD (modified PM Positioner Type II) in the treatment of OSA and to compare alterations in dental and skeletal positioning resulting from long-term use of MAD, using cephalometric radiographs in patients with and without osseointegrated implants. METHODOLOGY: The sample was collected in a database, cephalometric analyses, anthropometric and polysomnographic parameters of 44 patients with mild, moderate and severe OSA were evaluated before and after an average of 59 months of use of the MAD. The sample was statistically evaluated using a generalized linear model by comparing measurements between groups, the adopted significance level was 5%. RESULTS: No significant differences were found (p > 0.05) between the groups with and without osseointegrated implants in terms of improvement in polysomnographic parameters and side effects of dental and skeletal origin. CONCLUSION: The PM Positioner Type II proved to be effective in the treatment of OSA in terms of improving polysomnographic parameters in patients with and without osseointegrated implants. Changes in dental and skeletal positioning after using the MAD were similar between both groups during the study period.
