“…In our study, two patients described an increase of sleep quality after 24 hours of wearing the OSA and at three months follow-up they reported to use the OSA during the night, when contractions were too strong, in order to get muscle relaxation and a good sleep. This result is in accordance with Rosar et al’s findings that short-term interocclusal appliance therapy had a positive effect on sleep quality [ 33 ].…”

ObjectivesThe aim of this study was to assess the therapeutic efficiency of the occlusal stabilization appliance (OSA) in patients with cervical dystonia (CD).MethodsThe study included 11 patients aged between 29 and 80 years, 7 women and 4 men, diagnosed with primary CD. The patients underwent an extra- and intra-oral clinical examination, followed by para-clinical examinations, necessary for the specifications of the OSA. The following data were recorded: demographic parameters, CD duration, management of the disease, dental impression, recording of the centric relationship, recording of the position of the upper jaw with the facial bow. A standardized OSA was manufactured in a private dental laboratory. Patients received instructions for wearing the OSA for 24 hours. Patients filled a questionnaire designed by us, which evaluated the effects of wearing the OSA over a 24-hours period on the symptoms of CD: muscles contraction, pain, discomfort while walking, sleep quality, tremor. The patients kept the dental appliances, and after three months they completed the questionnaire one more time.ResultsThe OSA was applied on the lower arch in 3 (27.3%) patients and on the upper arch in 8 (72.7%) patients. The OSA wearing time for the first 24 h was on average 19.2±6 hours. Total relaxation of dystonic muscles was reported by 9 (81.8%) patients, while 2 (18.2%) patients related partial muscle relaxation. Seven (63.6%) patients reported a pain decrease. Increased comfort while walking was observed by 8 (72.7%) patients. Two (18.2%) patients described an increase of sleep quality. In two (18.2%) patients the tremor disappeared. All patients reported difficulties while eating and removed the OSA during meals. Patients who wore the OSA for more hours, experienced a pain decrease (p=0.08), an increase in sleep quality (p=0.1), the disappearance of the tremor (p=0.1). After three months, only seven patients continued to use the OSA. More patients described a pain decrease after three months (5 (71.4%) vs. 4 (57.1%); p=0.5), relaxation of dystonic muscles (7 (100%) vs. 6 (85.7%); p=0.3).ConclusionsThe use of OSA might be beneficial in CD patients, as it reduced the dystonic symptoms, pain severity and improved the quality of sleep.

“…A further purpose is to reduce the potential for damage caused by bruxism on tooth and implant supported prostheses. The long-term use of occlusal devices for this purpose have not been shown to reduce this force, 109,110 but occlusal devices can reduce individual tooth loading and distribute forces more evenly across the arch. 111 An SR incorporating five RCTs did not show effectiveness in treating sleep bruxism as a common outcome of an arousal index.…”

Purpose: The purpose of this Best Evidence Consensus Statement was to search the literature to determine if there is a relationship between patient specific factors and occlusal force. Materials and Methods: A literature review was conducted in the following databases: Evidence-Based Medicine Reviews (EBMR), Cochrane Database of Systematic Reviews, Embase, and Ovid MEDLINE(R) and Epub Ahead of Print. Articles on patient factors and occlusal force were compiled by using a combination of the key words: "bite force," "occlusal force," "partial and complete edentulism," "bruxism," and "orthognathic class." Inclusion criteria included meta-analyses, systematic reviews, randomized controlled trials, case series, and journal articles. Exclusion criteria were case reports, studies in children, animals, and bench studies. Results: Of the 1502 articles that met the initial search criteria, 97 related to patientspecific factors affecting occlusal forces. These articles were evaluated, rated, and organized into appropriate categories addressing questions of foci. Conclusions: The range of occlusal force is highly variable among subjects correlated to patient specific factors such as age, gender, partial and complete edentulism, the presence of a maxillofacial defect, location of edentulous area, orthognathic profile, and magnitude of occlusal vertical dimension. Tooth replacement therapies targeted at increasing occlusal contact seem to have a positive effect on increasing occlusal force. Bruxism does not necessarily demonstrate higher occlusal powering but may have greater tooth contact time. Occlusal force is not clearly affected by the type of dental restoration or restorative material used. The clinical significance of the changes in occlusal forces is yet to be determined.

“…These mandibular slides, in addition to moving the condyles out of their positions of musculoskeletal stability, may require muscle hyperactivity, altering their tonicity. This may lead to dysfunctions in the stomatognathic system characterised by MPD and orofacial pain involving the whole musculature of the masticatory apparatus [33,39].…”

Oral parafunction can be defined as an extra-functional action of certain components of the stomatognathic system. The automation of this kind of occurrence that persists in the form of a reflex arc is a denominated habit. The oral parafunctional habits are described as the action of clenching or grinding teeth (bruxism), among others. This work approached bruxism due to its clinical importance. To evaluate the predisposing factors to the development of oral parafunction, the orthodontist should have updated knowledge of the whole process of the phenomenon of bruxism. The purposes of this chapter were about the comprehension of the neurophysiology of bruxism and also about the capacity of structural adaptation of the components of the stomatognathic system, the analysis of its aetiological factors, as well as its implications on the structures of the masticatory system, and the verification of the relation between bruxism and the orthodontic treatment. In conclusion, the nature of that oral habit is multifactorial, which implies extrafunctional demand of neurophysiological mechanisms, whose effects are installed from the rupture of the structural limit of the adaptive capacity of the stomatognathic system, peculiar to each individual. The performance of orthodontic treatment is not related to the development of bruxism.
