Definitions

  • This application relates to maxillary and mandibular devices and methods of treating and/or diagnosing medical disorders and/or medical conditions using the same, more particularly, to a maxillary device that can provide electrical impulse stimulation to the muscle of the soft pallet and hard pallet, and/or the lateral pterygoid muscles to move the jaw forward.
  • OSA obstructive sleep apnea
  • snoring snoring
  • snore arousals sleep-related hypoxia
  • other conditions dependent on and caused by snoring or OSA OSA.
  • OSA is a condition in which sleep is repeatedly interrupted by an inability to breathe, which is typically a results of intermittent obstruction of the airway by the tongue and a general relaxation of the muscles which stabilize the upper airway segment, which can cause a lack of oxygen, snoring, cardiovascular and neurological complications, such as sleep-induced hypertension, heart attacks, cardiac arrythmias, strokes, Alzheimer’s disease, hypertension, sleep-induced hypertension, diabetes, weight gain, and depression.

  • the protrusive flanges 114 are generally an elongate linear flange protruding cranially from each of the housing 108.
  • the protrusive flange 114' is releasably attachable to the housing 108 of the mandibular piece 104.

  • the receptacle 126 will have a releasably attachable mating feature 128 that mates with the releasably attachable feature 146 of the post 144.
  • the releasably attachable mating feature 128 is a set of threaded holes and screws 129.
  • the protrusive flange 114' can have a bend 140 on the anterior side of the flange, but this is not required.
  • the new feature in this embodiment is that the posterior side 145 of the protrusive flange 114' is arcuately shaped as best shown in FIG. 8 as a concave surface, which mates with a driver 132 having a convex surface shaped to match the concavity of the posterior side 145.
  • the midpoint 147, relative to being the middle or halfway point between the free end 142 and the opposing end 143, of the arcuately shaped posterior side 145 defines an arc of a circle having its center at the temporomandibular joint (TMJ) in this illustration and the free end 142 has a width that is smaller than a width of the opposing end 143 of the flange.
  • the arc of the circle is one that defines 0i as being any angle with the range of 12 degrees to 15 degrees in increments of whole degrees, half degree, or 0.2 degree increments.
  • the angle of the arc 0i defines the amount of protrusion of the mandible with each degree of mouth opening. The larger this angle 0i, the greater the protrusion with mouth opening.
  • the arcuate surface is customizable to provide a curvature that provides the best forward movement of the mandible for the user in relation to the individual user’s mouth shape and size.
  • the radius defining the point of the arc may be offset by moving this point up or down relative to the midpoint 147, which may change the widths of the free end 142 and the opposing end 143.
  • the advantage to the arcuately shaped side 145 of the protrusive flange 114' is that it will help protrude the mandible forward as the Temporo-Mandibular joint (TMJ) relaxes and the mouth falls open during sleep, wake or any other transitional state of the human mind (such as various Parasomnia create) thus allowing gradual smooth arcuate incremental forward mandibular movement to occur as convex surface 145 of protrusive flange 114' smoothly glides against concave surface 136 of driver 132'.
  • the maximum protrusive distance (MPD) for anterior movement of the mandible is in a range of 6 mm to 10 mm.
  • the first 13 degrees of rotation of the mandible about the TMJ during natural, unaided spontaneous mouth opening does not move the mandible anteriorly, i.e., this rotation does not change or open the airway.
  • Drivers 130, 132 will actively coordinate simultaneous desired amount of vertical and protrusive movements of the mandible (controlled by controller) during this first 13 degrees of mouth opening while the arcuate opposing gliding movements of convex surface 145 of protrusive flange 114' smoothly against concave surface 136 of driver 132 'surfaces will passively create mild forward movement of the mandible.
  • Driver 132 will ensure constant contact between surfaces 145 and 136 while driver 130 will adjust height of oral cavity and thus increase oral cavity volume while simultaneously stiffening the soft palate and Uvula. This entire process will work in synergy (keeping the person’s sleep undisturbed) to increase cross-sectional area of upper airway and increase the cubic volume of the oral cavity which in turn allows 150L/R (through the controller) in 116 to appropriately incrementally protrude the base of tongue forward into the increased oral cavity volume utilizing electric stimulation of the tongue nerves and muscles (details described elsewhere in this document), further increasing the cross-sectional area of the upper airway (the tongue forms the anterior wall of the upper airway).
  • the mandible In the natural state, the mandible must rotate beyond this initial 13 degrees, typically through another 7 to 13 degrees to have an effect on the airway size.
  • the arcuately shaped side 145 is based on a 15 degree jaw rotation (end to end) curvature, i.e., qi and q2 are 15 degrees each or they may be any combination of two different angles that add up to 30 degrees.
  • Angle of q2 can be different from angle of qi, i.e. the arc may or may not be one fixed radius from TMJ.
  • Each of the qi and q2 should remain between the ranges of 12-15 degrees each although both qi or q2 or both could be zero degrees each (0-15 degrees each). These angles could exceed 15 degrees each based on individual needs of the user/patient. Total of (qi + q2) will ordinarily be between 24-30 degrees but could be 0-30 degrees or greater.
  • a q of 0 degrees will essentially create a straight vertical posterior surface 145 and would require a similar angle for surfacel36.
  • An angle of 180 would produce incremental forward protrusive movement of the mandible throughout the entire range of mandibular rotation (CR/CO to MMO) during mouth opening.
  • q2 is primarily useful to control neutral mandibular protrusion during the initial 13 degrees of mandibular rotation (although protrusive flange can protrude the mandible when using MRD with motorized protrusive flange option) but can be adjusted to produce protrusive movement (the more q2 is, the less the radius of mandibular incisor to TMJ, the less protrusion of the mandible during early rotation or mouth opening and the less q2 is the more protrusion with each degree of mandibular rotation).
  • qi is used to create the majority of the forward mandibular protrusion during the remainder of the mandibular rotation or mouth opening all the way to MMO (Maximum mouth opening).
  • MMO Maximum mouth opening
