Abstract
A dental implant system for securing a dental prosthesis within a prepared site of a jawbone in a subject having an implant configured for insertion within the prepared site of the jawbone and an abutment configured for secure attachment to the implant. The implant can have a shoulder portion having a plurality of circumferential rings and a body portion that can be threaded. The implant can have an internal cavity that is configured or otherwise adapted to receive at least a portion of the abutment.
Claims27
A dental implant system for securing a dental prosthesis therein a prepared site of a jawbone, the dental implant system comprising:
- an implant having a longitudinal axis, the implant comprising:
- a shoulder portion defining a coronal end of the implant and comprising a plurality of spaced circumferential rings;
- a implant body portion defining an apical end of the implant and having a longitudinal length and an implant thread, the implant thread substantially helically extending along at least a portion of the length of the implant body portion, wherein the implant body portion is tapered in an apical direction;
- and
- an internal cavity defined therein the coronal end of the implant and extending along the longitudinal axis of the implant therethrough the shoulder portion and at least a portion of the implant body portion;
- and
- an abutment comprising:
- a connector portion configured for selective secure attachment therein the internal cavity of the implant;
- a transition portion configured to abut the shoulder portion of the implant, the transition portion comprising a plurality of spaced circumferential rings, wherein the connector portion and the transition portion have a common longitudinal axis;
- and
- an abutment body portion, wherein the abutment body portion is tapered in a coronal direction,
- wherein, upon attachment of the connector portion of the abutment therein the internal cavity of the implant, the common longitudinal axis of the connector portion and the transition portion of the abutment is substantially axially aligned with the longitudinal axis of the implant.

- an internal cavity defined therein the coronal end of the implant and extending along the longitudinal axis of the implant therethrough the shoulder portion and at least a portion of the implant body portion;
- providing an abutment having a longitudinal length, the abutment defining an internal bore along its entire longitudinal length, the abutment comprising:
- a connector portion;
- a transition portion comprising a plurality of spaced circumferential rings, wherein the connector portion and the transition portion have a common longitudinal axis;
- and
- an abutment body portion, wherein the abutment body portion is tapered in a coronal direction,
- positioning the implant body portion therein the prepared site of the jawbone;
- securely attaching the connector portion of the abutment therein the internal cavity of the implant such that the common longitudinal axis of the connector portion and the transition portion is substantially axially aligned with the longitudinal axis of the implant and the transition portion of the abutment abuts the shoulder portion of the implant;
- inserting an abutment screw therein the internal bore of the abutment such that a threaded portion of the abutment screw is positioned therein the internal cavity of the implant;
- securing the abutment screw therein the internal cavity of the implant;
- and
- securing the dental prosthesis thereto the abutment.
