Abstract
Abstract Prefabricated construction element for an implant-fixed prosthesis, comprising a central portion (10) which can be attached to an implant-fixed anchorage element (14), and two from substantially diametrically opposite portions projecting wing-like portions (12), and the use of such construction elements for building up a unitary bridge body or a model of a bridge body by interconnecting the wing-like portions of adjacent construction elements which are mounted to implanted anchorage elements.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
65 words
Prefabricated construction element for an implant-fixed prosthesis comprising a central portion to be attached to an implant-fixed anchorage element, and to two wing-like portions integral with said central portion projection from substantially diametrically opposite positions of the central portion, each of said wing-like portions terminating at a free end to be connected to the free end of a wing of an adjacent prefabricated construction element.
Claim 2
Dependent Claim
65 words
Prefabricated construction element for an implant-fixed prosthesis comprising a central portion to be attached to an implant-fixed anchorage element, and to two wing-like portions integral with said central portion projection from substantially diametrically opposite positions of the central portion, each of said wing-like portions terminating at a free end to be connected to the free end of a wing of an adjacent prefabricated construction element.
Claim 3
Dependent Claim
19 words
Construction element as in claim 1 wherein a cap matching the anchorage element is attached to the central portion.
Claim 4
Dependent Claim
16 words
Construction element as in claim 2 wherein the element excepting the cap comprises a plastic material.
Claim 5
Dependent Claim
16 words
Construction element as in claim 3 wherein the plastic material comprises a fibre reinforced plastic material.
Claim 6
Dependent Claim
18 words
Construction element as in claim 1 wherein the central portion is shaped to match directly the anchorage element.
Claim 7
Dependent Claim
18 words
Construction element as in claim 5 wherein the construction element in its entirety consists of a plastic material.
Claim 8
Dependent Claim
26 words
Construction element as in claim 5 wherein the central portion consists of a metal compatible with tissue, and wherein the wings consist of a plastic material.
Claim 9
Dependent Claim
19 words
Construction element as in claim 1 wherein the element in its entirety consists of a metal compatible with tissue.
Claim 10
Dependent Claim
95 words
Implant-fixed prothesis including a plurality of prefabricated construction elements, each construction element including a central portion to be attached to an implant-fixed anchorage element, and two wing-like portions integral with said central portion projecting from substantially diametrically opposite positions of the central portion, each of said wing-like portions terminating at a free end to be connected to the free of a wing of an adjacent prefabricated construction element; wherein adjacent wings of the construction elements when mounted to the implanted anchorage elements are matched to each other and are interconnected to a unitary bridge body.
Claim 11
Dependent Claim
95 words
Implant-fixed prothesis including a plurality of prefabricated construction elements, each construction element including a central portion to be attached to an implant-fixed anchorage element, and two wing-like portions integral with said central portion projecting from substantially diametrically opposite positions of the central portion, each of said wing-like portions terminating at a free end to be connected to the free of a wing of an adjacent prefabricated construction element; wherein adjacent wings of the construction elements when mounted to the implanted anchorage elements are matched to each other and are interconnected to a unitary bridge body.
Claim 12
Dependent Claim
76 words
Prefabricated construction element for an implant-fixed prosthesis comprising a central portion to be attached to an implant-fixed anchorage element, and two wing-like portions projecting from substantially diametrically opposite positions of the central portion, each of said wing-like portions terminating at a free end to be connected to the free end of a wing of an adjacent prefabricated construction element, and said wings including a separate element which is rotatably and displaceably connected to the central portion.
Claim 13
Dependent Claim
76 words
Prefabricated construction element for an implant-fixed prosthesis comprising a central portion to be attached to an implant-fixed anchorage element, and two wing-like portions projecting from substantially diametrically opposite positions of the central portion, each of said wing-like portions terminating at a free end to be connected to the free end of a wing of an adjacent prefabricated construction element, and said wings including a separate element which is rotatably and displaceably connected to the central portion.
