Update on Oral Appliance Therapy for OSA

Area of Science:

• Sleep Medicine
• Dental Sleep Medicine
• Respiratory Medicine

Background:

• Obstructive sleep apnea (OSA) is highly prevalent in adults.
• Oral appliance (OA) therapy is a growing treatment option, especially for mild OSA.
• This review synthesizes current evidence supporting OA therapy.

Purpose of the Study:

• To update the evidence base for oral appliance therapy in obstructive sleep apnea.
• To compare the efficacy and adherence of OA therapy versus other treatments.
• To assess the impact of OA therapy on daytime sleepiness and long-term outcomes.

Main Methods:

• Systematic review of existing literature on oral appliance therapy for OSA.
• Analysis of comparative effectiveness studies between OA and CPAP.
• Evaluation of data on patient adherence, side effects, and long-term efficacy.

Main Results:

• Oral appliances (OAs) demonstrate effectiveness in treating obstructive sleep apnea (OSA).
• Continuous positive airway pressure (CPAP) generally shows higher efficiency, but OA adherence may compensate.
• CPAP is more effective for severe OSA-related daytime sleepiness; OA effectiveness for mild OSA sleepiness is uncertain. Long-term OA effectiveness is unclear due to side effects and potential OSA progression.

Conclusions:

• Oral appliances are effective for OSA, but with more variable outcomes than CPAP.
• Further research is essential to understand OA mechanisms, subjective patient experiences, and long-term health impacts.
• The role of OAs in managing OSA, particularly long-term, warrants continued investigation.
