Abstract
Abstract Introduction CPAP was previously considered the “gold standard” due to its high efficacy in eliminating obstructive events. Despite improvements in technology, the “effectiveness” of CPAP has been compromised by poor real-world compliance. Technological improvements have improved the “effectiveness” of Oral Appliances. This study reports the efficacy of a novel, precision engineered Oral Appliance for the primary treatment of all severities of OSA. Methods Digital scans and digital bite registrations were recorded with a George Gauge utilizing a a 3mm bite fork. Initial protrusion was set at 40–60% and varied according to the degree of overbite and overjet, the severity of OSA, and the presence or absence of TMJ symptoms. All patients were fitted with a ProSomnus (IA) MAD and titrated according to their subjective symptoms. An efficacy study was obtained with a HST after titration and compared to the initial PSG or HST. Results Outcome data on 85 patients (37 female, 48 males, aged 56.7 +/1 10.2 years) was retrospectively reviewed. The patients were consecutively ordered for follow up data, many patients did not return for follow ups. The pre-treatment AHI was 24.5 +/- 19.1 with 36 patients Mild, 26 Moderate and 23 Severe patients. O2 Nadir was 84.1% +/- 5.5%. Post treatment AHI was 5.5 +/- 4.9 with an AHI reduction of 71.6% +/- 20.3%. 59% of the patients scored <5, 31% 10 on the outcome AHI data. O2 Nadir improved to 88.2% overall. 31 patients had RERA’s (RDI-AHI) >10 with an average of 16.7 +/- 7.5, of these patients 27 saw a reduction of RERA’s of 54.4% from 16.9 to 7.1. Conclusion The data shows that a precision oral appliance is capable of successfully treating patients with all levels of severity, with the majority of patients treated to an AHI<5. 23 severe patients with an average AHI of 49.7 were treated to a final average of 8.6, 4 of the patients scored above 10. Additionally, patients successfully saw a reduction in upper airway resistance airflow as evidenced by a reduction of RERA’s of 54.5%, showing that a precision oral appliance can have a significant impact on the upper airway.
