Abstract
A flat blank of circular segmental shape having a recessed chord and made of thermoplastic material is heated in a bath of hot water in the range of 145 degrees F. (63 degrees C.) and 160 degrees F. (71 degrees C.) to render the material soft and supple. The blank is then manipulated and pressed in applying it to a dental arch for forming a facing alongside the oral cavity into which a throat insert is to be inserted for protecting the teeth of the arch from being injured, such as by being cracked or chipped, by impact with the teeth of such a throat insert or its appendages.
Claims1
A method for installing a throat insert in a throat which comprises:
- warming a flat thin substantially uniform thickness sheet blank of thermoplastic material to change such material from hard condition to soft supple condition;
- placing the blank, which is of a size and shape to be received within the oral cavity, over a dental arch alongside the oral cavity;
- pressing the blank manually onto and around the teeth of the dental arch and thereby deforming the blank into contiguous engagement with the teeth of the dental arch;
- cooling the liner in place to body temperature to restore the hardness of the liner for providing a shield for the teeth of the dental arch alongside the oral cavity while leaving the oral cavity substantially unobstructed and leaving the jaws unimpaired to move open and closed;
- inserting a throat insert past the liner formed in place on the dental arch into and through the oral cavity and into the throat while the liner remains in shielding position on the dental arch undisturbed by manipulation of the throat insert being inserted into and through the oral cavity;
- and
- removing the throat insert from the throat and out of the oral cavity while the dental arch remains shielded by the liner.
