US 9,308,059 B2 · Implant bite registration jig and bite impression fabrication method using the jig

Abstract

An implant bite registration jig includes a coupling portion configured to produce a clear impression in bite impression material; a connecting portion that connects the implant jig with a fixture embedded in a patient's gums; and a body that is formed between the coupling portion and the connecting portion. The implant bite registration jig is positioned in an embedded fixture and a bite impression is taken. Reference marks are formed in the bite impression material by the registration jig, which permit accurate location of the fixture. This makes it possible to simultaneously take a dental impression and a bite impression in an implant operation, similar to a natural teeth operation, such that it is possible to reduce the cost and time for manufacturing a prosthesis.

Dependent claims

An implant bite registration jig for fastening to a fixture embedded in a patient's gums so as to take a bite impression, and for separating from the fixture after taking the bite impression, the implant bite registration jig comprising:

a coupling portion that supports a bite material, the coupling portion including a cylindrical upper section having a constant diameter followed by an inclined lower section in which the diameter of the inclined lower section is gradually reduced with increasing distance from the upper section;
a connecting portion configured to connect the implant jig with the fixture embedded in the patient's gums via a section of the connecting portion having threads and a cylindrical, non-threaded portion above the threads;
and
a body that is formed between the coupling portion and the connecting portion, the body including a cylindrical section having a body diameter that is smaller than the constant diameter of the upper section of the coupling portion and that smoothly transitions from the inclined lower section of the coupling portion,
wherein the implant bite registration jig has a driver seat hole that is formed in a polygonal prism shape through a top of the coupling portion so as to receive a fastening tool for assembling or separating the implant jig with or from the fixture and to enable removal of the bite material after the bite impression is taken,
wherein a bored portion having a diameter larger than a cross-section of the driver seat hole is formed at an inlet of the driver seat hole,
wherein the bored portion is stepped,
wherein the bite material can be received in a volume of the bored portion so that an amount of the bite material received in the driver seat hole is reduced in taking the bite impression, and
wherein an inner surface of the driver seat hole and an inner surface of the bored portion are shaped to enable removal of the bite material.

6 more elements

a body having first and second ends;
a coupling portion at the first end of the body, having a shape configured to produce a clear reference mark in a bite impression material, to be separable, once the impression material is sufficiently cured, from a resulting bite impression without damaging the reference mark, and to be received by the reference mark so as to be securely held by the bite impression, the coupling portion including a cylindrical upper section having a constant diameter greater than a diameter of the body which is followed by an inclined lower section in which the diameter of the inclined lower section is gradually reduced with increasing distance from the upper section to smoothly transition into the first end of the body;
and
a connecting portion at the second end of the body, configured to engage an aperture in an implant fixture via a section of the connecting portion having threads and a cylindrical, non-threaded portion above the threads,
wherein the implant bite registration jig has a driver seat hole that is formed in a polygonal prism shape through a top of the coupling portion so as to receive a fastening tool for assembling or separating the implant jig with or from the fixture and to enable removal of the bite material after the bite impression is taken,
wherein a bored portion having a diameter larger than a cross-section of the driver seat hole is formed at an inlet of the driver seat hole,
wherein the bored portion is stepped,
wherein the bite material can be received in a volume of the bored portion so that an amount of the bite material received in the driver seat hole is reduced in taking the bite impression, and
wherein an inner surface of the driver seat hole and an inner surface of the bored portion are shaped to enable removal of the bite material.
