Abstract

An endosseous implant for prosthetic teeth comprising at least two spaced apart pairs of spaced apart relatively thin, flat vertically straight legs, each leg having a constant thickness and width from top to substantially the bottom, and preferably, a vertically tapered tip on the bottom of each leg, an upwardly arcuate, relatively thin, flat upper bridge joining the tops of the outermost legs of each said pair, an upwardly arcuate relatively thin, flat lower bridge vertically spaced apart from the upper bridge joining the tops of the innermost legs of each said pair, the bridges having a constant thickness preferably equal to the thickness of the legs, a relatively thin, flat arm joining the inner and outer leg of each said pair in proximity to their tops and preferably extending between the juncture of the legs with the respective bridges to which they are joined, the arms having a constant thickness preferably equal to the thickness of the legs, and a post formed on the uppermost bridge extending vertically upwardly therefrom, the top of the post preferably having at least one pair of intersecting grooves, the legs, bridges and arms collectively preferably having a plurality of transverse openings.

Claims

1. An endosseous implant for prosthetic teeth, comprising, a. at least two spaced apart pairs of spaced apart relatively thin, vertically straight legs, each leg having a constant thickness and width from the top to substantially the bottom, the distance between the said pairs of legs being greater than the distance between the respective legs of each pair, b. an upwardly arcuate, relatively thin, flat upper bridge joining the tops of the outermost legs of each said pair, c. an upwardly arcuate relatively thin, flat lower bridge vertically spaced apart from the upper bridge joining the tops of the innermost legs of each said pair, d. a relatively thin, flat arm joining the innermost and outermost leg of each said pair in proximity to their tops, and e. a post formed on the uppermost bridge extending vertically upwardly therefrom.

2. An endosseous implant for prosthetic teeth comprising, a. the structure in accordance with claim 1 in which b. the said legs, bridges and arms are collectively provided with a plurality of transverse openings.

3. An endosseous implant for prosthetic teeth comprising, a. the structure in accordance with claim 1 in which, b. each arm and each bridge has a constant thickness.

4. An endosseous implant for prosthetic teeth comprising:

a. the structure in accordance with claim 1 in which b. each leg has a constant width from the top to substantially the bottom.

5. An endosseous implant for prosthetic teeth comprising a. the structure in accordance with claim 2 in which b. each leg has a constant width from the top to substantially the bottom.

6. An endosseous implant for prosthetic teeth comprising, a. the structure in accordance with claim 5 in which b. each arm and each bridge has a constant thickness.

7. An endosseous implant for prosthetic teeth comprising, a. the structure in accordance with claim 6 in which b. the legs, arm and bridges have substantially the same constant thickness.

8. An endosseous implant for prosthetic teeth comprising, a. the structure in accordance with claim 2 in which b. the legs of each pair are spaced apart a distance substantially less than distance between the said pairs.

9. An endosseous implant for prosthetic teeth comprising, a. the structure in accordance with claim 2 in which, b. the top of the post is provided with a pair of intersecting grooves.

10. An endosseous implant for prosthetic teeth comprising, a. the structure in accordance with claim 2 in which a. a plurality of posts formed on the uppermost bridge extending vertically upwardly therefrom, the posts being positioned symmetrically with respect to a vertical axis through the center of the said bridges, c. at least one supporting arm joining the uppermost and lowermost bridges, the supporting arm being symmetrical with respect to a vertical axis through the center of the said bridges.
