Single Retainer All-Ceramic Resin-bonded Fixed Dental Protheses
This trial is active, not recruiting.
|Conditions||restauration in situ, final loss of restauration, debonded restauration|
|Treatments||multilink bonding, panavia 21 tc|
|Sponsor||University of Kiel|
|Collaborator||Ivoclar Vivadent AG|
|Start date||October 2006|
|End date||April 2008|
|Trial size||30 participants|
|Trial identifier||NCT01411592, Ivoclar ZirCAD Adh.bruecken|
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.
