Oral appliance

An oral appliance adapted for repositioning the temporomandibular joint of a user having an uneven spacing between the teeth of the upper and lower jaws, said appliance including a generally U-shaped base portion shaped so as to be locatable in use between the teeth of the upper and lower jaws of a user and leading and trailing flange means along the leading and trailing edges of said base portion and extending to opposite sides thereof so as to form upper and lower channels for accepting the teeth of the upper and lower jaws and wherein said base portion tapers in thickness on both sides of said appliance from regions adjacent the trailing ends of said appliance towards the leading end thereof so as to substantially occupy said uneven spacing between said teeth of said upper and lower jaws to provide a support for the jaws of the user and cause said lower jaw to move forwardly and downwardly into alignment with said upper jaw.

An oral appliance for repositioning the temporomandibular joint of a user having an uneven spacing between the teeth of the upper and lower jaws, said appliance including a generally U-shaped base portion adapted to be located between the teeth of the upper end lower jaws of said user, said base portion having on opposite sides of said appliance a maximum thickness at regions adjacent trailing ends of the appliance, said base portion tapering in thickness on both sides of said appliance from said regions towards the leading end of said appliance and from said regions towards the trailing ends thereof so as to define a base portion having on opposite sides a longitudinal cross section of a substantially asymmetric aerofoil shape whereby said base portion may substantially occupy said uneven spacing between said teeth of said upper and lower jaws to provide a support for the jaws of the user.
