Abstract
The invention relates to a tooth implant (10) for application in the human jaw bone, with a cylindrical bore (20), which is open toward a distal end (16) and is designed to receive a longitudinal portion of an abutment (50), wherein a first longitudinal portion (22) of the bore (20) adjacent to the distal end (16) has a first cylindrical guide surface (28). In the area of the first longitudinal portion (22), at least two cams (30) are provided, which protrude radially inward and in each case have a second guide surface (36) lying concentric with respect to the first guide surface (FIG. 1b).
Claims20
A tooth implant for application in the human jaw bone, having a cylindrical bore, which is open toward a distal end for receiving a longitudinal portion of an abutment, wherein a first longitudinal portion of the bore adjacent to the distal end has a first cylindrical guide surface, wherein, in the area of the first longitudinal portion, at least two cams are provided, which protrude radially inward and in each case have a second guide surface lying concentric with respect to the first guide surface.
An abutment device for a tooth implant for application in the human jaw bone, wherein the tooth implant has a cylindrical bore which is open toward a distal end and is designed to receive a longitudinal portion of the abutment device, wherein a first longitudinal portion of the bore adjacent to the distal end has a first cylindrical guide surface, wherein, in the area of the first longitudinal portion, at least two cams are provided, which protrude radially inward and in each case have a second guide surface lying concentric with respect to the first guide surface, and wherein said abutment device comprises a cylindrical longitudinal portion whose external diameter corresponds to the diameter of the first guide surface and which has at least a number of grooves corresponding to the number of cams, said cams and grooves together serving to prevent rotation of said abutment device relative to said tooth implant.
A closure screw device for a tooth implant for application in the human jaw bone, wherein the tooth implant has a cylindrical bore, which is open toward a distal end and is designed to receive a longitudinal portion of an abutment, wherein a first longitudinal portion of the bore adjacent to the distal end has a first cylindrical guide surface, wherein, in the area of the first longitudinal portion, at least two cams are provided, which protrude radially inward and in each case have a second guide surface lying concentric with respect to the first guide surface, and wherein said closure screw device comprising a head, which closes the bore of the tooth implant, a guide portion adjoining the head, and a threaded portion that engages with the thread of the second longitudinal portion of the tooth implant, wherein the diameter of the guide portion corresponds to the diameter formed by the second guide surfaces of the cams of the tooth implant.
