Assessment of Treatment Outcome after Using Temporary Mandibular Advancement Devices in Obstructive Sleep Apnea Patients

Purpose: The aim of this study was to evaluate the effect of temporary mandibular advancement devices (MAD) in obstructive sleep apnea (OSA) patients Methods: 28 patients (male 21, female 7) undergoing temporary mandibular advancement device treatment for OSA were selected from 2011.01. to 2012.02. in the department of Oral & Maxillofacial Surgery at SamsungMedicalCenter. Treatment efficacy was determined by polysomnography (PSG) at baseline & after MAD delivery. The response group was defined as ＞50 % Apnea-Hypopnea Index (AHI) reduction plus post-MAD AHI ＜10, and the non-response group was defined as ＜50 % AHI reduction. The lateral cephalogram was analysed including SNA, SNB, UL, MPH, PAS, PASU, and PAST using V-cephTM (Cybermed, USA). Results: The responsers were 23 patients, and non-responsers were 5 patients. The AHI was significantly reduced with temporary MAD (8.08±7.93) compared with baseline (28.51±20.56) in the response group (n=23). No significant differenc
