简要总结

Background: Obstructive sleep apnea syndrome (OSAS) is a prevalent condition with significant comorbidities. Mandibular advancement devices (MADs) are an established alternative for patients intolerant to continuous positive airway pressure (CPAP) therapy. However, potential side effects, particularly within the craniomandibular system, warrant further investigation.

Objective: This randomized controlled Phase IV trial aims to compare two different MAD designs (UPS-1 by Scheu Dental and UPS-2 by Panthera X3) in terms of patient acceptance, wearing comfort, adherence, and side effects, especially occlusal changes and temporomandibular discomfort, in OSAS patients over a 12-month period.

Methods: Twenty-eight patients will be stratified by sex and randomized 1:1 into two treatment groups. Assessments include acceptance of the MAD, clinical and digital occlusal analysis (GEDAS), functional examination (DC/TMD), sleep parameters (AHI, ESS, DI), and patient-reported outcomes. Follow-ups were scheduled at 4 weeks, 6 months, and 12 months post-insertion. Data were collected using standardized CRFs and validated questionnaires. Statistical analysis was based on ordinal regression and intention-to-treat and per-protocol populations.

Results & Conclusion: This study will provide evidence on the comparative efficacy and tolerability of two distinct MAD systems, contributing to improved treatment selection in personalized OSAS management.

详细描述

Partial obstruction of the upper airway during sleep leads to snoring in approximately 40% of men and 24% of women. Epidemiological studies indicate that 50% of these individuals suffer from obstructive sleep apnea syndrome (OSAS) (1, 2).

Sleep-related breathing disorders (SRBD), particularly OSAS, are among the most common causes of non-restorative sleep and sleep disorders. Characteristic patterns include apneas and hypopneas, which may occur with or without pharyngeal obstruction and hypoventilation. Depending on the type of breathing disorder, they may be associated with hypoxemia and can lead to hypercapnia or acidosis.

The consequences of obstructive pharyngeal narrowing are far-reaching. Studies have demonstrated that patients with OSAS frequently experience comorbidities such as neurological disorders, myocardial infarctions, dementia, cardiovascular diseases, and higher mortality rates (3-8). Sleep fragmentation due to nocturnal breathing disturbances and arousals may result in daytime sleepiness and impaired concentration. In the long term, untreated apneas and arousals increase the risk of arterial hypertension, stroke, myocardial infarction, diabetes mellitus, and reduced libido.

Therapeutic options during sleep include continuous positive airway pressure (CPAP) therapy, mandibular advancement devices (MADs), positional therapy, weight reduction, surgical interventions in the ENT region, bimaxillary or mandibular osteotomies, and hypoglossal nerve stimulation.

The choice of therapy depends on the severity of OSAS. For mild to moderate OSAS, MADs, positional therapy, and weight loss are viable options. In severe OSAS, CPAP therapy remains the gold standard. Osteotomies, offering effects comparable to CPAP, and hypoglossal nerve stimulation are reserved for specific clinical cases. In certain cases, a multimodal approach, including surgical methods, may be appropriate regardless of OSAS severity.
