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.
