Clinical capability of zirconia resin-bonded prostheses

Abstract

Zirconium dioxide (zirconia) ceramics have excellent biocompatibility, superior mechanical properties, and favorable esthetics. Zirconia is therefore used as an alternative to metal alloy framework materials in tooth- and implant-supported fixed dental prostheses (FDPs), and implant abutments. To replace a missing anterior tooth, some treatment options are available, such as conventional FDPs, resin-bonded fixed dental prostheses (RBFDPs), and implant-supported fixed dental prostheses. Tooth preparation for RBFDPs is significantly less invasive compared with conventional FDPs. A number of clinical studies demonstrated that zirconia-based RBFDPs led to positive clinical outcomes being suggested as a conservative treatment modality. To achieve long-term stability of zirconia-based RBFDPs, strong and durable bonds between abutment teeth and zirconia frameworks are mandatory. The aims of the present article are to clarify clinical outcomes of the zirconia-based RBFDPs and describe clinical approaches including selection of the case, tooth preparation, and bonding procedures for the long-term success of zirconia-based RBFDPs.
