Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
194 words
Means for implanting an artificial tooth in the jawbone comprising in combination, a stud anchored securely into the jawbone and having a tooth supporting portion which extends above the jawbone, at least one thin flexible blade-like member secured to said stud and extending laterally outwardly therefrom, and a hollowed tooth housing defining an interior cavity to snugly receive said stud and the attached member, said housing cavity having an interior dimension at its entrance end which is less than that of said blade-like member in its unflexed condition such that said housing can be moved into this final intended position on said stud only by flexure of said flexible member in the direction of movement of said housing into its intended position on said stud, said housing defining an outwardly extending recess in the wall of its cavity to receive said flexible member in its normal substantially unflexed position, said recess and said member being so positionally interrelated that said flexible member snaps into position in said recess as said housing assumes its final intended position on said stud, the outer surfaces of said tooTh being secured to the outer surfaces of said housing.

Claim 3
Dependent Claim
26 words
The combination of claim 1 in which said flexible member forms part of a spring clasp which extends across and is rigidly secured to said stud.
Claim 4
Dependent Claim
22 words
The combination of claim 2 in which said spring clasp has a flexible member at each end extending outwardly of said stud.
Claim 5
Dependent Claim
18 words
The combination of claim 3 in which said spring clasp is secured to said stud by a screw.
Claim 6
Dependent Claim
86 words
The combination of claim 3 in which said spring clasp is formed to have a flat central portion which is secured to said stud, a pair of slanting surfaces symmetrically disposed about either side of said central portion and adapted to overlie opposite side portions of said stud, and short outwardly extending tab portions which are engaged by inner surfaces of the cavity of said housing upon the placement of said housing on said stud and are thereby bent inwardly toward the sides of said stud.
Claim 7
Dependent Claim
41 words
The combination of claim 5 in which at least one of said sloping surfaces on spring clasp has an inwardly extending integral tab portion and the mating portion of said stud has a recess to receive said inwardly extending tab portion.
Claim 8
Dependent Claim
25 words
The combination of claim 1 in which said stud is provided with a threaded shaft portion which is adapted to be screwed into the jawbone.
