All-ceramic dental materials, such as zirconia (Zr) and lithium disilicate (LD), have become increasingly popular compared to the standard porcelain fused to metal (PFM) and complete cast metal materials, due to their strength and likeness to natural human teeth. With this recent shift in preference, there are currently several methods practiced to adhere a crown to a tooth. My project, in conjunction with the College of Dental Medicine at Midwestern University, is a systematic review of the literature to determine the optimal bonding protocol for indirect zirconia restoration to natural teeth. An exhaustive search will be performed utilizing various search engines to find current literature using the following designations: cementing procedure, zirconia crowns, and bonding protocol. The texts will be examined and sorted based on zirconia type, intaglio surface preparation, intaglio surface primer, cement type, methods of tooth surface preparation (total etch, selective etch, or self etch) and adhesive strengths between tooth and restoration.
