A ceramic/metallic dental abutment for use with an implant, the abutment generally including a ceramic body portion having a base region, a transgingival region, and a supragingival region. The base region includes an anti-rotational implant interface, such as an external polygonal fitting, for engaging a cooperating internal polygonal fitting of an implant to prevent relative rotation between the abutment and the implant. The ceramic abutment body portion additionally includes a metal implant contact portion for contacting the implant and providing a load-bearing, metal-on-metal interface between the abutment and the implant.

L'invention concerne un aboutement dentaire céramique/métallique pour une utilisation avec un implant, l'aboutement comprenant généralement une partie corps céramique présentant une région de base, une région transgingivale, et une région supragingivale. La région de base comporte une interface d'implant antirotative, comme un raccord polygonal externe, permettant l'engagement avec un raccord polygonal interne conjugué d'un implant pour empêcher toute rotation relative entre l'aboutement et l'implant. La partie corps d'aboutement céramique contient en outre une partie de contact d'implant de métal afin de toucher l'implant et de constituer une interface porteuse de charge de métal à métal entre l'aboutement et l'implant.
