Devices for connecting a dental prosthetic construction to a jawbone

摘要

A male piece for reversible and detachable connection of a dental prosthetic construction to a jawbone, said male piece being designed with a fastening structure, by means of which the male piece can be fastened onto the jawbone, onto an implant that has been implanted in the jawbone, onto a tooth stump or onto a neighboring tooth, comprising a body section having an exterior surface corresponding to a lateral surface of a cylinder, such that the central axis of the cylinder defines a longitudinal axis of the male piece; a snap-on section, which is offset axially with respect to the longitudinal axis of the male piece relative to the body section, said snap-on section, comprising an exterior surface with a convex curvature along the longitudinal axis, which protrudes outward from the longitudinal axis of the male piece beyond the exterior surface of the body section; and a head end, which terminates the male piece axially with respect to its longitudinal axis, wherein the snap-on section is arranged closer to the head end than is the body section, and a concave intermediate section is arranged between and the head end and the convexly curved exterior surface of the snap-on section.

1. A male piece for reversible and detachable connection of a dental prosthetic construction to a jawbone, said male piece being designed with a fastening structure by means of which the male piece can be fastened onto the jawbone, onto an implant that has been implanted in the jawbone, onto a tooth stump or onto a neighboring tooth, comprising:
a body section having an exterior surface corresponding to a lateral surface of a cylinder, wherein the central axis of the cylinder defines a longitudinal axis of the male piece; a snap-on section, which is axially offset with respect to the longitudinal axis of the male piece relative to the body section, said snap-on section comprising an exterior surface with a convex curvature along the longitudinal axis, which protrudes outward beyond the exterior surface of the body section from the longitudinal axis of the male piece; and a head end which closes the male piece axially with respect to its longitudinal axis, wherein the snap-on section is arranged closer to the head end than is the body section, and wherein a concave intermediate section is arranged between the head end and the convexly curved exterior surface of the snap-on section, wherein the head end of the male piece completely is convexdly curved and closed, the head end of the male piece corresponds to a segment of a spherical surface, and the segment of the spherical surface of the head end has a first radius of curvature and the convexly curved exterior surface of the snap-on section has a second radius of curvature, wherein the first radius of curvature is greater than the second radius of curvature.
