Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
44 words
Retaining device for removable dental prosthesis comprising a ball member and a socket member, one of which is to be implanted in the alveolar bone while the other is fixed to the dental prosthesis, to be engaged to one another by a snap action.
Claim 2
Dependent Claim
44 words
Retaining device for removable dental prosthesis comprising a ball member and a socket member, one of which is to be implanted in the alveolar bone while the other is fixed to the dental prosthesis, to be engaged to one another by a snap action.
Claim 3
Dependent Claim
34 words
Device according to claim 1, wherein said member to be implanted in said alveolar bone is made of rigid material and said member to be fixed to the prosthesis is made of resilient material.
Claim 4
Dependent Claim
23 words
Device according to claim 2, wherein said relatively rigid material is selected from biocompatible resins and said resilient material is a biocompatible rubber.
Claim 5
Dependent Claim
67 words
Device according to claim 1, wherein said ball member comprises a substantially cylindrical shaft part to be implanted in said alveolar bone, joined to a rounded head part, and said socket member comprises a plug to be attached in a corresponding cavity made in the inner wall of said dental prosthesis with a hollow whose shape is the imprint of said head part of said ball member.
Claim 6
Dependent Claim
27 words
Device according to claim 4 wherein said shaft part to be implanted in said alveolar bone has a roughened external surface and numerous spaced grooves around it.
Claim 7
Dependent Claim
75 words
Device according to claim 2, wherein said ball member comprises a rounded body joined to a broadened base destined to be fixed in a corresponding cavity in the inner wall of said dental prosthesis and said socket member comprises a substantially cylindrical shaft part destined to be implanted in said alveolar bone, joined to a broadened head part with a hollow on the top the same shape as said rounded body of said ball member.
Claim 8
Dependent Claim
27 words
Device according to claim 6, wherein said';shaft part destined to be implanted in said alveolar bone has a roughened outer surface and numerous spaced grooves around it.
Claim 9
Dependent Claim
66 words
Device according to claim 2, wherein said ball member comprises a substantially cylindrical shaft part destined to be implanted in said alveolar bone joined to a rounded head part with grooving around the edge, and said socket member comprises a spring clamp destined to be fixed to said dental prosthesis in a position which allows engagement with said depression in said head of said ball member.
Claim 10
Dependent Claim
27 words
Device according to claim 8 wherein said shaft part to be implanted in said alveolar bone has a roughened external surface and numerous spaced grooves around it.
Claim 11
Dependent Claim
83 words
Device according to claim 2 wherein said ball member comprises a broadened perforated saddle-shaped base destined to be implanted in said alveolar bone, with a pin joined to its outer surface with a rounded head on the end and said socket member comprises a plug of resilient material destined to be fixed in a corresponding cavity in the inner wall of said dental prosthesis with a hollow whose shape is the imprint of said head part of said pin of said ball member.
