Analysis of the Effects of a Mandibular Advancement Device on Sleep Bruxism Using Polysomnography, the BiteStrip, the Sleep Assessment Questionnaire, and Occlusal Force

Abstract

The MAD treatment resulted in the reduction of SB activity, SB signs and symptoms, sleep disorders, and occlusal force.

Management of sleep bruxism in adults: a qualitative systematic literature review

“…Thus, fourteen papers were included in the review. Of them, twelve were RCTs and two were uncontrolled before–after studies .…”

“…Seven papers report on the effectiveness of oral appliances (OA), either with a before–after or with a RCT design . The latter includes comparison groups treated with gabapentin , with palatal appliances , or adopting different protocols as far as the intermittent vs continuous appliance wearing , the different vertical dimension of occlusion (VDO) and the appliance design are concerned.…”

Evaluation of various treatment modalities in sleep bruxism

“…10,[15][16][17]31 The mechanism behind the positive effect of the MAD may be explained by the forward movement of the mandible, which increases the airway space and reduces microarousals, allowing deeper stages of sleep, as most bruxism episodes (80%) occur in the light-sleep stage. 32 However, further studies are needed to clarify this, as there are other hypotheses regarding the mechanism. 16,31,33 In contrast, the mechanism behind the MOS is that it reduces the nocturnal massetric and temporalis muscle activity by improving the muscular balance.…”

TMD/Orofacial Pain and OSA, Correlation or Causation?

“…We have heard that expression called the new meaning of the acronym WNL, and I have to say I would agree with it given my anecdotal observations of dentists and how they view their existing patient population at improvement of these symptoms with the use of the said occlusal/night guard or flat plane splints [31][32][33][34]. However we do see improvements in these pain symptoms when the mandible is advanced with anteriorly advancing orthotic therapy [35][36][37], and improvements again with mandibular advancements in patients with UARS [38] and OSA [39][40][41], along with the well observed significant reduction in SB with mandibular advancement [42][43][44][45][46].…”
