Summary

The purpose of this prospective study was to evaluate the clinical outcome of all-ceramic RBFDP with a cantilevered single-retainer design made from zirconia ceramic. To evaluate the impact of the adhesive system used an established resin cement with an integrated adhesive monomer (Panavia 21 TC) and a resin cement with a separate primer (Multilink Automix with Metal/Zirconia Primer) were compared within the study on a randomized basis. The aim of the present randomized study was to evaluate wether the difference in bond strength of Panavia and Multilink Automix with Metal/Zirconia Primer to densely sintered zirconia ceramic (IPS e.max ZirCAD, Ivoclar Vivadent) has any impact on the clinical outcome of all-ceramic RBFDP with a cantilevered single-retainer design.

Conditions

• Restauration in Situ
• Final Loss of Restauration
• Debonded Restauration

Interventions

Type	Name	Description
OTHER	Multilink	After air-abrasion of the retainer wings (50 µm alumina particles at 0.25 MPa) and etching the enamel with 36% phosphoric acid for 30 sec, the RBFDPs were inserted using an adhesive bonding system with a phosphonic acid acrylate primer for the zirconia ceramic (Multilink-Automix bonding system with Metal/Zirconia primer)
OTHER	Panavia 21 TC	After air-abrasion of the retainer wings (50 µm alumina particles at 0.25 MPa) and etching the enamel with 36% phosphoric acid for 30 sec, the RBFDPs were inserted using a phosphate monomer containing resin (Panavia 21 TC) without any primer
