Copy-Milled All-Ceramic Celay-InCeram Crowns for Modified CeraOne Abutments: A Technical Report
Pröbster, Lothar / Girthofer, Stephan / Groten, Martin / Rein, Bettina
With single-tooth implant restorations, a divergence between implant and crown axes, a lack of interocclusal space, and supracrestal implant placement may result in fabrication problems for the prosthetic crown. It was found that the CeraOne abutment can be modified in three ways: (1) height reduction is possible; (2) a 15-degree taper can be applied; and (3) the cervical shoulder can be reduced in height with a chamfer remaining. For these modified abutments, the Celay-InCeram system was used to create individual, all-ceramic crowns for these modified abutments with improved esthetics.
