Retention Of Zirconia Crowns Following Different Bonding Protocols, Suruchi Lamba

All ETDs from UAB

Objective: To measure and compare the retention of zirconia crowns cemented with Ceramir (Calcium phosphate-based Bioactive Cement), RelyX Luting Plus (RMGI Cement) and RelyX Unicem (Self-adhesive resin cement) to extracted teeth following thermocycling. Methods: 30 sound extracted non-carious human molars were collected following IRB approval. The selected molars were notched at the roots and mounted into PVC molds filled with acrylic resin (Yates Motloid, USA). The occlusal surface was ground flat on a model trimmer. The axial reductions were performed with a standardized crown preparation device using a Komet 5845KR (“onlay”) diamond bur. A 10 degree ramp was used to …
