Official Title: A Proof of Concept for All-ceramic Zirconia Resin Bonded Bridges for Canine, Premolar and Short Span Posterior Teeth Official Title:
Brief Summary:
Trial Design - Objectives and Purpose The aim of this study is to perform a proof of concept for the successful retention and outcome measures of zirconia RBBs for the replacement of missing canine or posterior teeth (6-8mm span) and that they will exhibit similar survival rates (95%) as metal ceramic RBBs over 3 years and short term (Botelho 2006).
The use of monolithic extra-coronal zirconia RBBs in the posterior region does not appear to have been reported in the literature (A search pf Pub Med and Google Scholar has not shown any similar studies that have been published - pubmed.gov; Keywords: "zirconia", "resin", "clinical" assessed on 17/10/2015 AND google scholar; Keywords: "zirconia", "resin bonded fixed partial denture", "resin bonded fixed dental prosthesis", "Maryland", "resin bonded bridge" "posterior", "clinical") In addition, currently there appear to be no clinical trials planned or finished in this area (clinicaltrial.gov; Keywords: "zirconia", "resin" assessed on 17/10/2015) using zirconia RBBs in the posterior region. This reveals that there is a gap in the literature on the use of zirconia for replacing posterior teeth with such prostheses.
The primary outcome measures would be: success ie. prosthesis retention ie. does not fall out
The secondary outcome measures would be:
