Definitions

  • This invention relates to an interdental immobilization device.
  • the existing method of the prior art uses a pliable metal strip with projecting hooks known as an arch bar and several fine wires and rubber bands.
  • the metal strip is secured tightly to the teeth of the upper jaw by passing a wire around the base of a tooth and through the gum and over each side of the tooth and also over the metal strip. At this point, both ends of the wire are outside the mouth and are twisted together to hold the metal strip urgingly against the outside surface of the teeth.
  • the twisted wire is then cut to a length of approximately 1/8 to 1/4 inch and bent backward towards the gum and preferably placed in between two adjacent teeth to prevent irritation on the inside of the lips.
  • the metal strip has the projecting hooks spatially disposed on its outside surface and over these hooks .[.small.]..Iadd.. Small .Iaddend.rubber bands or wires are then attached between those hooks of the metal strip attached to the teeth of the lower jaw and those hooks of the upper jaw.
  • This technique has been published at pages 301 through 303 in Surgery of the Upper Respiratory System (Vol 1-2nd Edition) by William W. Montgomery M.D., published by Lea & Febiger, Copyright 1979.
  • the wires need to be retightened and retwisted as they have a tendency to loosen off and sometimes break. If they break during tightening, the patient must be re-anesthetized again within the operating theatre and new wires inserted as before. Further, the patient must be anesthetized for wire removal after the jaw has mended.
  • the fixture may be tightened by the simple expedient of turning down a nut on a flexible screw as there is no wire twisting with .[.these appendant.]. .Iadd.the attendant .Iaddend.possibilities of wire breakage and blood letting; thus, the prior art step for re-installation of broken wires in an operating theatre environment with the patient anesthetized is avoided; not to mention the associated blood letting; and,
  • the invention is disclosed as a novel three part fixture, and in another embodiment it is a four part fixture; both of these embodiments employ frusto-conical surfaces or alternative truncated cones as a pair, or in combination with a nut and screw.
  • These fixtures expose an anchoring surface associated with the nut, which preferably is cylindrical, onto which rubber bands or wires may be attached so as to fix the lower .[.and upper.]. jaw into rigid position.
  • the interdental immobilization device is but a two part fixture, a .[.yieldable.]. .Iadd.deformable .Iaddend.stainless steel shaft with .[.one.]. .Iadd.a proximate .Iaddend.end .[.as a threaded.]. .Iadd.comprising an adjacent .Iaddend.helical .[.shaft.]. .Iadd.threaded portion .Iaddend.that extends into a smooth .[.continuous shaft.]. .Iadd.cylindrical rod .Iaddend.that then tapers into a pointed .[.tip.].
  • the nut defines a smooth bored channel sized slightly smaller in diameter than that of the threaded .[.shaft.]. .Iadd.portion.Iaddend..
  • the nut is composed of a plastic material such as nylon.
  • the channel has a shorter major .[.bore.]. .Iadd.portion .Iaddend.with diameter larger than that of the threaded .[.shaft.]. .Iadd.portion .Iaddend.that steps into a longer minor .[.bore.]. .Iadd.portion .Iaddend.with diameter slightly smaller than that of the threaded .[.shaft.].

  • the nut have a truncated cone portion with the channel intersecting the truncation, and wherein the truncated cone portion extends into a cylindrical piece bounded by a bearing surface such as a hexagon or knurl.
  • the .[.shaft has means to index itself into.]. .Iadd.proximate end is deformed to mate with a slot in .Iaddend.one of the cones .[.as well as.]..Iadd..
