This article describes a case of rehabilitation of a missing lateral incisor using a Zirconia based resin bonded fixed partial denture. An 18 year old female patient with the agenesis of lateral incisor and a peg lateral incisor in the other side presented to prosthetic department .This aspect was compromising the self satisfaction of the patient. She desired a more attractive appearance. After a comprehensive examination, adjacent teeth to edentulous area were sound with a suitable height. Implant therapy was excluded. The treatment plan included a Zirconia based resin bonded bridge in the right side. The peg lateral incisor was reshaped using a provisional restoration until growth achievement and tissues maturation
Purpose: To assess the survival rates and incidences of complications of posterior zirconia based fixed dental prostheses. Material and Methods: An electronic literature search of Medline (PubMed) was conducted independently by three reviewers to identify clinical studies from 2006 to 2016 and was completed by a manual search. Key words, inclusion and exclusion criteria were well defined. Results: The search revealed 419 titles and led to the final analysis of 19 full text articles, 11 studies met the inclusion criteria, one was a randomized clinical study with 3 years follow up results. The others were cohort prospective studies. Technical complications included chipping of veneering porcelain which was the most frequent complication. However, biological complications, included: secondary caries, abutment fracture and marginal discoloration. The survival rates of zirconia based short unit FDPs are promising, and for FDPs with long spam, further randomized controlled clinical trials are necessary. An important improvement of the veneering system is required. Conclusion: Short and long term clinical data suggest that posterior zirconia based fixed dental prosthesis may serve as an alternative to metal ceramic fixed dental prostheses in the posterior dentition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
