Predicting treatment response to mandibular advancement therapy using a titratable thermoplastic device

Area of Science:

• Sleep Medicine
• Medical Devices
• Obstructive Sleep Apnea Treatment

Background:

• Mandibular advancement device (MAD) therapy is a common second-line treatment for obstructive sleep apnea (OSA).
• A subset of patients do not respond effectively to MAD therapy.
• Predicting treatment success is crucial for optimizing patient care.

Purpose of the Study:

• To evaluate the predictive utility of a trial with a thermoplastic MAD.
• To determine if thermoplastic MAD outcomes can forecast success with custom-made MADs.
• To assess the correlation between thermoplastic and custom-made MAD effectiveness in OSA patients.

Main Methods:

• Patients used a thermoplastic MAD as a trial before custom-made MAD fabrication.
• Sleep recordings and clinical outcomes were compared after 6 months with each device.
• Predictive value for custom-made MAD success (AHI < 10, >50% reduction) was assessed.

Main Results:

• A significant correlation was found between thermoplastic and custom-made MADs' impact on AHI, oxygen desaturation, snoring, and sleepiness.
• High positive predictive value (86%) for AHI decrease was observed.
• Low negative predictive value (46%) for AHI decrease was noted.

Conclusions:

• Thermoplastic MADs show similar impacts on OSA severity markers and symptoms as custom-made MADs.
• Thermoplastic MADs may serve as a useful tool to predict custom-made MAD success for OSA.
• Further controlled studies are needed to confirm the predictive ability of thermoplastic MADs.
