Method and apparatus for diagnosing sleep apnea
View Patent ↗A method and apparatus for diagnosing sleep apnea and for comfortably fitting an oral device to treat the condition. The patient is screened to reduce snoring using a device which changes the airway, and then using an airway dilation simulator having sequentially sized elements to determine the mandibular position maximizing the upper airway dimension. An oral device is then fabricated to retain the maximum position during sleep.
1. A kit for determining and simulating the optimal airway dilation by adjusting jaw position for a person having obstructive sleep apnea, comprising a plurality of similar discrete rectangular elements having different height dimensions, having ends, a thickness and sides, wherein each element includes opposing slots extending inwardly from the ends, each element further contains a notch mid-point on one side and at least two notches on the opposite side, said notches determining a jaw position in a horizontal plane when a person's incisors are placed in the notches, said elements further having predetermined end dimensions to control the jaw position in a vertical plane.
2. A diagnostic kit for determining and simulating a person's optimal airway dilation in cooperation with the person, having jaws and teeth, by manipulating juxtaposition of upper and lower jaws by engaging the teeth, comprising a pair of related devices, a first elongated, rectangular screening device having an upper and a lower surface including a stepped portion on one end to engage upper front teeth and a smooth graduated lower surface to note protrusion of a person's mandible defining maximum airflow and a starting position to be refined using a second device, which comprises a plurality of rectangular discrete elements, having a thickness of graduated height dimensions including one notch on the lower surface and at least two notches on the upper surface for engaging the teeth, enabling a quick interchange of discrete elements for a person's subjective assessment of comfort at varying positions near the starting position.
3. A kit as in claim 2 , wherein the second device includes multiple elements.
4. A kit as in claim 2 , wherein the discrete elements are compatible with a pharyngometer.
5. A set of tools for diagnosing breathing disorders by determining an optimal horizontal and vertical position of a person's incisors to maximize airflow, including a set of discrete airway dilation simulators, including positioning notches therein to receive the upper and lower incisors controlling relative vertical and horizontal positions of the person's incisors, enabling comparative airway measurements, wherein the simulators are thin and are compatible with and allow pharyngometer testing of a person's jaw and airway dimension in simulated positions when the airway dilation simulators and the pharyngometer are in place in a person's mouth; wherein the airway dilation simulators include slots extending inwardly from opposing ends thereof.
6. The set of tools of claim 5 , including in combination therewith a bite fork which includes a horseshoe shaped main body portion with a plurality of spaced openings and a projecting mounting member having an inwardly projecting slot adapted to mate with a corresponding slot in a dilation simulator.
