Objectives
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.
