“…This clockwise rotation of the mandible upon mandibular opening can be explained as a counteract effect to the forward movement enforced by the MAD. Similar to previous findings [24][25][26][31][32][33][34], OJ and OB were significantly reduced by 1.07 mm and 0.99 mm, respectively. These results can be attributed to the retroclination of the upper incisors and proclination of the lower incisors.…”

“…These results agree with those obtained by Chen et al [49]. Overall, it was concluded that the sagittal tooth relationship between the maxillary and mandibular anterior teeth saw a reduction with the continuous use of MADs, irrespective of the design and materials used [18,24,25,31,34,49,50]. In recent systematic reviews, MADs for OSA may reportedly tilt the mandibular incisors to 1.54 ± 0.16°labially, reduce the OJ by 0.89 ± 0.04 mm, reduce the OB by 0.68 ± 0.04 mm, and rotate the mandible downward [13].…”

“…However, patients find that these symptoms improve throughout the day, and the level of discomfort is reportedly minimal [17,18,[26][27][28][29][30]. On the contrary, long-term dental changes or changes in occlusion are harder for the patients to notice [16]; these include OJ and OB reduction, a forward shift of the mandibular molars, and increased maximal opening [24][25][26][31][32][33][34]. The findings in this study demonstrate that, as previously shown in other studies with other ethnicities, Japanese OSA patients also experience several dentoskeletal changes after a continuous long-term use of MAD therapy.…”

Dentoskeletal changes caused by the long-term use of mandibular advancement devices (MADs) for obstructive sleep apnea (OSA) have rarely been investigated in Japan. We assessed the long-term dentofacial morphological changes in 15 Japanese patients with OSA who used two-piece MADs for an average of 4 years. Lateral cephalography analyses were performed initially and 4 years later (T1). The dental assessment included overjet, overbite, upper anterior facial height, lower anterior facial height (LAFH), total anterior facial height (TAFH), and anterior facial height ratio. Dental casts were digitized and analyzed using a 3D scanner. Changes in the apnea hypopnea index (AHI) and other sleep-assessment indices were assessed using polysomnography and out-of-center sleep testing. Radiography revealed lingual inclination of the maxillary central incisors, labial inclination of the mandibular central incisors, clockwise rotation of the mandible, and an increase in the TAFH and LAFH at T1. In the dental cast analysis, the diameter width and palatal depth tended to decrease and increase, respectively. There was a significant decrease in the AHI and other sleep assessment indices after using the MADs for approximately 4 years. However, these findings do not provide a strong basis and should be interpreted cautiously. Future studies should have a larger sample size and should further investigate the long-term occlusal and dental changes caused by the original MADs in Japanese patients with OSA.
