Appl. No.:

10/356735

Inventors:

Michael R. Klardie - Bloomington MN, US
Robert D. Carter - Apple Valley MN, US
Peter B. Swenson - Eden Prairie MN, US
Richard L. Tvedt - Savage MN, US
John De Angelo - Hillsborough NJ, US

Assignee:

Lifecore Biomedical, Inc. - Chaska MN

International Classification:

A61C 8/00

US Classification:

433173

Abstract:

The present invention is an impression cap for use with an implant/abutment impressioning system for taking impressions of cement-on-crown abutments to mirror the contour of the soft tissue and bone in a patient's mouth. The impression cap is configured to uniquely fit over one of an abutment and a dental implant via a novel flange. The flange is located at the bottom of the impression cap forming a bottom rim and is constructed to grasp the collar of an implant in a press, friction fit manner. The flange of the impression cap automatically captures the implant margin by pushing gingival tissue away when the component is seated.

International Classification:

A61C008/00

US Classification:

433/174000

Abstract:

A dental implant may be prepared by roughening or coating a desired portion of a dental implant blank and removing material from the dental implant blank subsequent to roughening the dental implant blank. By removing material, a cutting flute with a cutting edge, cutting surface and collector surface may be formed. The cutting surface and collector surface is relatively smooth compared to the cutting edge.
