Zirconia Cementation: Increasing Predictability

Too often, clinicians use the ceramic type of restoration as the first consideration for the type of cement to use, and preparation design becomes the last factor contemplated. This article explains how in order to maximize the effectiveness of ceramic restorations, clinicians need to determine the process by which they select which cement to use in every indirect cementation process and to understand how zirconia differs from classic glass ceramics. Solid understanding of these two elements will increase the long-term predictability of indirect zirconia restorations, improving relationships with patients and decreasing stress points in daily schedules.

LEARNING OBJECTIVES:

• Review important factors in determining type of cement to use.  

• Clarify the advantages and disadvantages of different cements. 

• Describe the different priming techniques for bonding zirconia restorations.
