Trial Summary

What is the purpose of this trial?

This trial tests if a mouthpiece that keeps the lower jaw forward can help people who frequently urinate at night by improving their sleep. These devices have been used to help with breathing issues during sleep.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are using combination therapy for obstructive sleep apnea, such as positive airway pressure therapy, you may not be eligible to participate.

What data supports the effectiveness of the treatment Somnodent Classic for nocturia?

Mandibular advancement devices, like Somnodent Classic, have been shown to improve sleep quality and reduce snoring in people with obstructive sleep apnea, which might indirectly help with nocturia (frequent nighttime urination) by improving overall sleep patterns.12345

Is the Mandibular Advancement Device safe for humans?

Mandibular advancement devices, like Somnodent, are generally well-tolerated and considered safe for treating conditions like snoring and sleep apnea. Some studies report good acceptance and minor side effects, but there can be dental and skeletal changes over time.13567

How does the treatment Somnodent Classic differ from other treatments for nocturia?

The Somnodent Classic is a mandibular advancement device, typically used for sleep apnea, that works by adjusting the position of the lower jaw to improve airflow during sleep. This approach is unique for nocturia (frequent nighttime urination) as it is non-invasive and primarily targets sleep-related breathing issues, which may indirectly affect nocturia symptoms.12345

Eligibility Criteria

This trial is for adults over 18 with obstructive sleep apnea (AHI≥5) who experience at least two trips to the bathroom per night. Participants must have ≥8 teeth per arch, be able to move their jaw forward by ≥5mm, and speak English. People can't join if they're pregnant, have certain medical conditions like heart failure or diabetes, use diuretics, or are already using other treatments for sleep apnea.

Findings from Research

Mandibular advancement devices have been shown to significantly improve symptoms of obstructive sleep apnea syndrome (OSAS), particularly by reducing the frequency of apneas and hypopneas, which leads to better sleep quality and less snoring as reported by bed partners.
Polysomnographic improvements were noted, with some patients achieving an apnea-hypopnea index of less than 10 per hour, although results varied, with some individuals experiencing no improvement or worsening of their condition.

The mandibular advancement device (MAD) Somnoguard significantly reduced the respiratory disturbance index (RDI) in 44 patients with obstructive sleep apnea (OSA), indicating improved breathing during sleep.
68% of patients experienced either a cure or substantial improvement in their condition, along with a notable increase in minimal oxygen saturation and a decrease in snoring time, demonstrating the device's efficacy as an alternative treatment for those noncompliant with continuous positive airway pressure.
