ABSTRACT:
An implant assembly for the anchoring of an artificial tooth in a jawbone comprises a root fixture for anchoring into the jawbone; a metal sleeve resting on top of the root fixture and having a tapering upper section acting as a male element; and a connector element having a lower part secured to the root fixture and an upper part holding the metal sleeve, the upper part being covered by the sleeve. The assembly further includes a combination made up of an artificial tooth having a bore and a counterbore, and a metal insert solid with the tooth and mounted within the counterbore. The insert is cup-shaped at one end and, acts as a female element. It also includes an outwardly flaring internal lateral wall. The tapering upper section and the outwardly flaring lateral wall are shaped and sized so as to fit snuggly one into the other in the manner of a male and female joint (coupling). A screw arrangement tightly secures the tooth combination to the root fixture through the connector element.
