Dental anchor apparatus and method

摘要

A dental anchor apparatus having a one or two part endosseous implant securable in a patient's mouth and a retention member which is releasably engageable with the implant. The implant has an abutment head at one end and a threaded post projecting from the head and designed for threaded engagement in the jaw bone, the head having an outer locating surface portion. The retention member is generally cupshaped with a first end and a peripheral skirt extending from the first end to form a cavity, the skirt having an inner locating surface which is engaged over the outer locating surface portion of the head. The head may also have a socket in which a post extending from an inner end of the retention member engages as the parts are moved into releasable snap engagement.

主权项

1. A dental assembly comprising:
a) an endosseous dental implant comprising:
(i) a first end portion having a top and a bottom, the first end portion comprises:
(1) an external projection extending from the top of the first end portion for releasable engagement with an abutment member, wherein the abutment member has an external lower bevel portion; and(2) an annular cuff portion defining an annular seat having a recessed, inwardly tapered bevel surface, wherein the tapered bevel surface surrounds the external projection; and wherein the lower bevel of the abutment contacts and seats on tapered bevel surface of the annular seat to form a line of connection when the abutment member is releasably engaged with the external projection, wherein the line of connection is located slightly below a patient's gum line when the implant is secured in the mouth of the patient; and(ii) a threaded post which extends from the bottom of the first end portion for direct engagement into the patient's bone or tissue; and b) an abutment with an internally threaded bore for threadable engagement with the external projection.
