Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
213 words
A throw-away teeth protector for use during medical incisions and treatments, comprising: an arcuate base member formed of an elastic material, said base member having a substantially channel-shaped cross section with the inside wall thereof being higher than the outside wall and wherein the bottom of the channel on the outside is provided with protrusions which are spaced apart to form a free space between the base member of a protector applied on one jaw and the teeth of the opposite jaw, the bottom protrusions being positioned unsymmetrically with respect to the symmetry axis in the plane of the base member so that the bottom protrusions are displaced with regard to each other when two identical teeth protectors are used simultaneously in both jaws, the ends of the channel being open and a string of plastic material being positioned in the arcuate channel inside the ends of said base member, said string being plastic and elastic and non-curing at room temperature and said string having a free surface which is adapted to be forced against the points of the teeth to be protected, when the protector is to be used, so that the teeth are embedded at least partially in the plastic material, the plastic material being maintained plastic and non-curing in use.
Claim 2
Dependent Claim

Claim 5
Dependent Claim

Teeth protector according to claim 3, in which the ridges, before the use of the protector, pass the ends of the plastic string.
Claim 6
Dependent Claim
