Objectives
Currently the common method to replace single missing teeth when finances or medical health issues exclude dental implants is the use of resin-bonded bridges. However these are metallic and can have potential health issues. With the move towards CAD-CAM dental prostheses there is a growing use of Zirconia for conventional dental bridges. This has not been reported on for routine use of missing teeth using resin bonded bridges. Therefore the aim of this study is to perform a proof of concept for Zirconia resin bonded bridges. Trial Design - Objectives and Purpose To perform a proof of concept clinical study for the replacement of missing canine or posterior teeth 6-8mm in span using an all-ceramic zirconia RBB and to compare the success rate to the existing literature from this centre – 95% over 3 years (Botelho 2002). The primary outcome measures would be: success ie. prosthesis retention ie. does not fall out The secondary outcome measures would be: • complications of the prosthesis such as tipping, drifting or fracture. • patient centered outcomes (satisfaction and oral health related quality of life) on the RBBs The hypothesis is that 2-unit cantilevered zirconia RBBs will be as successful as current data on 2-unit cantilevered metal-ceramic RBBs from this centre and that there will be no difference in the patient centered outcomes. The Primary endpoint will be a 6 monthly review appointment up to the 36 month of the study. Therefore this could be up to a maximum of 5 review appointments.
