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.
