When dental implants are used to support single crowns, it is likely that the immobility of the implant could alter the clinical performance of the implant-retained crown when compared with crowns made for natural teeth. The situation may be further complicated by the material choice for the transmucosal abutment. This article evaluates a number of factors that may influence clinical performance when lithium-disilicate crowns are made using two different abutment materials.
