Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
96 words
Dental prosthesis, comprising: a. a base formed of rigid material carrying artificial teeth and having a cavity having the general conformation of the gum of the user, b. a molding of concavo-convex cross-section formed of resilient material adapted to fit between the said cavity and the gum of the user, and c. a mounting element fastened to the base and having an adhering surface engaging the molding, the mounting element consisting of a lamination of fabric layers, the layers contacting the molding having coarse fibres extending from it to lock into the surface of the molding.
Claim 2
Dependent Claim
96 words
Dental prosthesis, comprising: a. a base formed of rigid material carrying artificial teeth and having a cavity having the general conformation of the gum of the user, b. a molding of concavo-convex cross-section formed of resilient material adapted to fit between the said cavity and the gum of the user, and c. a mounting element fastened to the base and having an adhering surface engaging the molding, the mounting element consisting of a lamination of fabric layers, the layers contacting the molding having coarse fibres extending from it to lock into the surface of the molding.
Claim 3
Dependent Claim
27 words
Dental prosthesis as recited in claim 1, wherein the molding has its convex surface coated with a layer of fabric that locks favorably with the mounting element.
Claim 4
Dependent Claim
20 words
DeNtal prosthesis as recited in claim 1, wherein the material of which the base is formed is an acrylic polymer.
Claim 5
Dependent Claim
