The best result for e.max was Multilink Hybrid Abutment. The best result for zirconia was 3M's RelyX Ultimate. The best result for Enamic was with Panavia VS and RelyX Ultimate. MultiLink Hybrid Abutment was slightly lower. 4) Self Adhesive cements and Glass Ionomer cements are indicated for high-strength restorative materials only (e.g.
• Avoid any contact of phosphoric acid with the zirconia restoration during the cementation process. The phosphate ion in the acid greatly reduces any potential bonding to the zirconia. • Do not clean the tooth preparations with prophy paste. The emollients and fluoride in some prophy pastes can be negative and cause crowns to come off. crowns, cement retained implant crowns/bridges Resin-Modified Glass Ionomer, Self Adhesive Resin Highly esthetic restorative material with translucency similar to natural teeth and e.max, but stronger.

Did zinc phosphate cemented crowns commonly come off the abutment teeth during service? No, that happened only very infrequently, and then only when the tooth preparations were nonretentive. This empirical evidence alone should add credibility to the statement that bonding is not essential for zirconia or lithium disilicate crowns placed over adequately retentive tooth preparations. Zirconia Crown Cementation Tip: If sandblasting is done in laboratory before try-in, clean saliva contamination with NaOCl (ca. 5%) and rinse with water.

However, the use of a metallic abutment may compromise the gingival aesthetics of implant crowns, I am now able to create shaded zirconia abutments that eliminate that problem. They look great and the shade is throughout the abutment not just on the surface. If the crown is not bonding, ask your lab to leave flat surfaces or slight grooves on the abutment. The … Association of custom-made zirconia abutments with emax crowns in implant rehabilitations: a zirconia abutment with a Procera crown and a custom metal abutment with metal ceramic crown.
