Summary
Oral appliance therapy offers an effective alternative for managing obstructive sleep apnea (OSA), improving symptoms like snoring and daytime sleepiness. While patient acceptance is high, further research is needed to overcome limitations before it can replace CPAP as a first-line treatment.
Area of Science:
- Sleep Medicine
- Dental Sleep Medicine
- Respiratory Medicine
Background:
- Obstructive sleep apnea (OSA) is a prevalent disorder causing airway closure during sleep, leading to sleep fragmentation and oxygen desaturation.
- OSA significantly impacts quality of life and is linked to cardiovascular issues like hypertension and stroke, as well as increased accident risk.
- Current gold-standard treatment, continuous positive airway pressure (CPAP), faces challenges with patient tolerance and compliance.
Purpose of the Study:
- To evaluate the efficacy and patient acceptance of oral appliances as an alternative treatment for obstructive sleep apnea (OSA).
- To compare oral appliance therapy with CPAP in managing OSA symptoms and patient outcomes.
- To identify limitations and areas for future research in oral appliance therapy for OSA.
Main Methods:
- Review of recent evidence, including randomized controlled trials, on oral appliance therapy for snoring and OSA.
- Assessment of oral appliance effectiveness in controlling OSA and improving patient-reported symptoms.
- Comparison of outcomes and patient acceptance between oral appliances and CPAP.
Main Results:
- Oral appliance therapy effectively controls OSA in up to 50% of patients, including some with severe forms, significantly improving snoring and daytime sleepiness.
- Patient acceptance of oral appliances is generally favorable compared to CPAP due to their unobtrusive nature.
- While CPAP shows overall superiority, oral appliances achieve similar outcomes in a substantial patient subgroup.
Conclusions:
- Oral appliance therapy is a viable and tolerable alternative for managing obstructive sleep apnea (OSA), offering significant symptom improvement.
- Further research is crucial to address limitations such as predicting treatment outcomes, optimizing mandibular advancement, and understanding long-term effects.
- Oral appliances show promise but require resolution of current challenges before potentially surpassing CPAP as a first-line OSA treatment.
