Study Published in "Military Medicine" Reports 88% Success Treating Obstructive Sleep Apnea Patients with Precision Oral Appliance Therapy

Treatment with Precision Oral Appliance Therapy Demonstrated Significant Improvements in Apnea-Hypopnea Events, Respiratory Disturbances, Oxygen Saturation, REM Sleep, Sleep Efficiency and Sleepiness

79.6% Reduction in Sleep Apnea Events with Precision Oral Appliance Therapy Relative to Baseline Testing

ProSomnus Precision Intraoral Medical Devices Exclusively Utilized in this Independent Study

SAN FRANCISCO, Dec. 08, 2022 (GLOBE NEWSWIRE) -- ProSomnus, Inc. (“the Company”) (NASDAQ: OSA), a pioneer in precision medical devices for the treatment of Obstructive Sleep Apnea (OSA), today announced the publication of a peer-reviewed, independent, study in Military Medicine, in which 88% of patients with Obstructive Sleep Apnea (“OSA”) were successfully treated using the Company’s novel precision intraoral medical devices. Following approval from the Carl R. Darnall Army Medical Center Institutional Review Board and the Defense Health Agency, the investigators analyzed the records of active-duty military patients treated for OSA to determine the success of precision oral appliance therapy (“OAT”) based on a symptom-driven titration.

“The U.S. military continuously looks for opportunities to enhance the wellness and readiness of all of its members,” said the principal investigator, Ryan Kang, DMD, MS, ABGD. “Sleep is an incredibly important factor in one’s overall health and daily performance, so we are especially interested in ways to improve soldiers’ rest. Our primary goal was to evaluate if OSA can be effectively managed with Precision OAT. This study suggests that Precision OAT has strong potential in managing patients’ OSA and makes a case for wider adoption of it throughout the military.”

The study demonstrated that 88% of patients were successfully treated with precision OAT to an Apnea-Hypopnea Index (“AHI”) of less than 10 events per hour, which was noted as better than previous studies that utilized non-precision, dental products. The study also reported statistically significant improvements in respiratory disturbances (“RDI”), oxygen saturation, REM sleep, sleep efficiency and daytime sleepiness, with a 79.6% mean reduction in sleep apnea events. For context, previous studies reported that success rates with traditional, non-precision, OAT were less than 65%.

“ProSomnus is honored to support the US Military and for our devices to be associated with high quality, independent research investigations,” said Len Liptak, Co-Founder and Chief Executive Officer of ProSomnus. “This study adds to the growing body of independent research demonstrating the success of ProSomnus precision oral devices for the treatment of OSA, further establishing ProSomnus devices as a leading option for patients and healthcare providers seeking an alternative to CPAP and Hypoglossal Nerve Stimulation treatments.”

About OSA
OSA is the recurring collapse of the airway during sleep, resulting in oxygen shortages and abrupt awakenings accompanied by gasping or choking. In addition to daytime sleepiness, OSA is associated with serious comorbidities, including heart failure, stroke, hypertension, morbid obesity and type 2 diabetes. Patients with untreated OSA are 23 times more likely to suffer a heart attack and four times more likely to have a stroke. It is estimated that more than one billion people worldwide and over 74 million people in North America suffer from OSA. Approximately 56 million of those 74 million people in North America are undiagnosed.

About ProSomnus
ProSomnus is the first manufacturer of precision, mass-customized Precision Oral Appliance Therapy devices to treat OSA, which affects over 74 million Americans and is associated with serious comorbidities, including heart failure, stroke, hypertension, morbid obesity and type 2 diabetes. ProSomnus’ patented devices are a more comfortable and less invasive alternative to Continuous Positive Airway Pressure (CPAP) therapy, and lead to more effective and patient-preferred outcomes. With more than 150,000 patients treated, ProSomnus’ devices are the most prescribed Precision Oral Appliance Therapy in the U.S. To learn more, visit
