“…This can be a possible explanation for the absence of significant changes in overjet and overbite. In a study by Ghazal and co-workers, a significant decrease in overbite but not overjet was found [25]. The appliance used in that study was a Thornton Adjustable Positioner like the one used in the present study.…”

“…At baseline and after 2 years of treatment, dental plaster study models in full occlusion, based on alginate impressions of the upper and lower dental arches, were obtained from all patients to determine clinically relevant variables related to the patient's occlusion [16, 21, 25]. The intermaxillary relationship between the upper and lower arch was recorded with the vinyl polysiloxan registration material Exabite II NDS TM (GC America Inc, Alsip, Il, USA) in maximal occlusion.…”

ObjectivesThis study aimed to assess possible dental side effects associated with long-term use of an adjustable oral appliance compared with continuous positive airway pressure (CPAP) in patients with the obstructive sleep apnea syndrome and to study the relationship between these possible side effects and the degree of mandibular protrusion associated with oral appliance therapy.Materials and methodsAs part of a previously conducted RCT, 51 patients were randomized to oral appliance therapy and 52 patients to CPAP therapy. At baseline and after a 2-year follow-up, dental plaster study models in full occlusion were obtained which were thereupon analyzed with respect to relevant variables.ResultsLong-term use of an oral appliance resulted in small but significant dental changes compared with CPAP. In the oral appliance group, overbite and overjet decreased 1.2 (±1.1) mm and 1.5 (±1.5) mm, respectively. Furthermore, we found a significantly larger anterior–posterior change in the occlusion (−1.3 ± 1.5 mm) in the oral appliance group compared to the CPAP group (−0.1 ± 0.6 mm). Moreover, both groups showed a significant decrease in number of occlusal contact points in the (pre)molar region. Linear regression analysis revealed that the decrease in overbite was associated with the mean mandibular protrusion during follow-up [regression coefficient (β) = −0.02, 95 % confidence interval (−0.04 to −0.00)].ConclusionsOral appliance therapy should be considered as a lifelong treatment, and there is a risk of dental side effects to occur.Clinical relevancePatients treated with the oral appliance need a thorough follow-up by a dentist or dental-specialist experienced in the field of dental sleep medicine.

“…Dieser Wert liegt über der in der Literatur beschriebenen Compliance von 51-55% nach 2-3 Jahren für UPS in der Behandlung schlafbezogener Atmungsstörungen und lässt auf einen hohen Tragekomfort des IST®-Geräts schließen [9,22].…”

“…Subjektiv das Gefühl einer Okklusionsveränderung hatten 8 von 34 unserer Schienenträger. Auch wenn dies in unserer Studie objektiv nicht untersucht wurde, so wird doch in der Literatur über dentale Nebenwirkungen -und hier v. a. über Veränderungen in der Inklination der Frontzähne -beim Langzeitgebrauch von Schienen [4,9] berichtet. Diese sind zumeist nur gering ausgeprägt, und ihre Bedeutung muss daher gegenüber dem großen therapeutischen Nutzen der Schiene individuell abgewogen werden.…”

“…Ghazal et al 12 , retrospectively examined the dental changes that occurred after patients had worn the Thornton Adjustable Positioner (TAP) for over two years (a device anchored on teeth in both arches and can therefore result in reciprocal forces leading to dental side effects) 12 . Evaluating consecutively diagnosed and treated patients for OSAS, they compared the baseline findings with follow-up findings after more than 24 months of continuous appliance wear.…”

Snoring and Obstructive Sleep Apnea (OSA) are caused by repetitive dynamic closure of the oropharyngeal airway. There exists substantial and growing epidemiologic evidence that OSA is associated with a variety of systemic conditions, including but not limited to, systemic hypertension, stroke, congestive heart failure, increased motor vehicle accidents, impaired quality of living and mortality. There is an equal amount of literature on the use of dental appliances as a treatment modality for OSA. The object of this report is to review the literature in regards to three vital aspects of this disease: a) the etiology and sequela of OSA; b) the dental management of the condition and its mode of action; and lastly, c) the positive and negative outcomes/risks, of dental management. KEYWORDS Obstructive Sleep ApneaOral devices Dental appliances treatment protocols.
