Efficacy of Non-adjustable Magnetic Mandibular Advancement Appliances (2M2A) in Patients with Mild Obstructive Sleep Apnea: a Preliminary Short-term Study

Objectives: 1) to assess the efficacy of the non-adjustable mandibular advancement device, namely Magnetic Mandibular Advancement Appliances (2M2A) in patients with mild obstructive sleep apnea (OSA), compared between pretreatment and 3-month after the insertion of the 2M2A, using apnea hypopnea index (AHI) and minimum oxygen saturation 2) tTo determine changes in craniofacial and upper airway structures in patients with mild obstructive sleep apneaOSA (OSA), treated with the oral appliance, namely Magnetic Mandibular Advancement Appliances (2M2A) 2M2A , by means of lateral cephalometric analysis. Furthermore, the efficacy of 2M2A was evaluated and compared between pretreatment and 3-month posttreatment using apnea hypopnea index (AHI) and minimum oxygen saturation.

Materials and Methods: Fifteen Thai subjects aged between 20 and 69 year-old with mild OSA who have failed to previous radiofrequency ablation treatment were recruited. Lateral cephalometric radiographs were taken twice; prior to and after the during 2M2A inserted in place. Polysomnography was performed 3-month posttreatment.

Results: Three-month after insertion of the 2M2A, average AHI was significantly decreased, whereas minimum oxygen saturation was significantly increased. When the 2M2A worn inserted in place, forward position and clockwise rotation of the mandible, an increase in lower facial height and decreases in ANB, overjet and overbite were significantly observed. Significant increase of upper airway width was also found during after the 2M2A inserted in place. Three-month posttreatment, average AHI was significantly decreased, whereas minimum oxygen saturation was significantly increased.

Conclusions: During After the 2M2A inserted in place, changes of mandibular position, enlargement of upper airway, and improvement of sleep quality AHI and minimum oxygen saturation was significantly observed in mild OSA patients.
