LOCKING TOOL FOR USE WITH ENOSSAL INDIVIDUAL TOOTH IMPLANT

摘要

The invention is directed to a tool having having concentric sleeves which move relative to one another with the inner sleeve having slots for receiving lugs on the base element and the outer sleeve having lugs or projections to be received in the slots on the ring element so that the ring element can be rotated relative to the base element, which is held by the inner sleeve. The tool of the invention is for use with an implant for an individual tooth including a metal implant post having a fastening head for receiving a removable denture, the implant post being mounted in a metal spacing element which is threaded in a basic structure that is implantable in the tooth. To hold the spacing element in a fixed, non-twisting and rotatable position, the element is composed of a base element having a first threaded portion which is received in the basic structure and a second threaded portion of a pitch less than the first threaded portion, which receives a ring element that is threaded thereon and has a shoulder for engaging an upper edge of the basic structure to form a locking arrangement.
