What this trial studies
Pregnant adults who snore will be fitted with a midline traction oral appliance and monitored with unintrusive home sleep recordings at baseline, during initial use, and after four weeks of nightly use. Each participant is expected to complete at least five consecutive weeks of participation, with the option to continue device use and periodic home recordings through the remainder of pregnancy. Objective breathing and sleep measures are collected for two consecutive nights at each time point, and participants complete brief surveys about sleep. Participants keep their oral appliance after the study.
Who should consider this trial
Good fit: Pregnant adults who currently snore, have at least eight teeth per arch, Mallampati I–II, palatine tonsils grade 0–2, can consent and use the home sleep recorder and appliance, and are ≤32 weeks pregnant are the intended participants.
Not a fit: People more than 32 weeks pregnant, those with uncontrolled serious illness, cardiovascular or rhythm disorders, TMJ problems, loose teeth/periodontal disease, prior UPPP, or who refuse to wear an oral appliance are unlikely to benefit from this intervention.
Why it matters
Potential benefit: If successful, the oral appliance could reduce snoring and improve sleep quality for pregnant people and potentially lower risks linked to pregnancy sleep-disordered breathing.
How similar studies have performed: Oral appliances have been shown to reduce snoring and mild-to-moderate obstructive sleep apnea in nonpregnant adults, but their use specifically in pregnant populations has been less studied.
