MARK MURPHY, DDS PREVENTING SIDE EFFECTS UNDESIRABLE JAW PAIN Preventing side effects is preferable to treating them. Joint pain can be caused by excessive OAT device titration, asymmetrical advancement or manufacturing variances. Modern precision design and fabrication techniques for OAT devices can mitigate variances, create more predictable experiences, and improves outcomes. Appropriate Titration Many dorsal style OAT devices have a 70 o angled post. The chart below demonstrates that protrusion is lost with a 70 o angled post design as the vertical opening increases. Advancing the mandible further or using elastics are common, compensating, techniques. Alternatively, the 90 o post design option of ProSomnus devices maintains the protrusive mandibular position even when the jaw opens. Many doctors report treating patients with less protrusion when using the 90 o post. Precision Manufacturing Variance in size, placement and angulation of the advancement mechanism (screw, rod, Herbst or post) is inherent in a traditional OAT device fabrication. To compensate, leading doctors report having to titrate one side of the OAT device differently. The photos below show observed and measurable inaccuracies in post size that are indicative of the traditional manufacturing method. Given that screw titration devices are often prescribed for adjustments of less than one mm, these variances are counterproductive. The ProSomnus CA device utilizes a precision manufacturing method, from device design to assembly, that mitigates these variances to create more predictable performance. 1.25mm difference between right and left advancement post of a traditionally fabricated device.
