A prospective 10-year follow-up dental cast study of patients with obstructive sleep apnoea/snoring who use a mandibular protruding device

ConclusionsLong-term nocturnal use of an MPD may cause both favourable and unfavourable occlusion changes, such as a decrease of the overjet and overbite or posterior infra-occlusion, and these changes may continue to develop during treatment with an MPD. Subjects with a Class III relationship may not be a suitable group for treatment with an MPD due to the mesial drift of the mandibular teeth.
