Vol. 12 – Number 47 – 2021 NOTEBOOK OF CLINICAL DENTISTRY Systematic review Page 113-125 Metal free partial fixed prostheses in posterior region – literature review considering longevity, ceramic material used, and main failures Nathalia Silveira Finck1 Juliana da Mota Paiva2 Rafael Dario Werneck3 Mariana Itaborai Moreira Freitas4 Priscilla Santos Guimarães5 Abstract This study aimed to present a literature review with data obtained in vitro and in vivo on metal free partial fixed protheses (PFP) in the posterior region, considering the following variables: ceramic material to be used; prosthesis extension; survival or longevity; main failures found, and comparison with the longevity of conventional metaloceramic PFP. A bibliographical survey was carried out using the databases: United States National Library of Medicine (PubMed) and Scientific Electronic Library Online (Sciello) for articles in English and Portuguese from 1998 to 2019. Articles should meet the inclusion criteria, which were articles that contained information that enabled the calculation of PFPs survival and success, articles with a minimum observation period of 3 years, articles that identified the reason of failures, and studies reported since 1998. Sixteen studies met the inclusion criteria and were evaluated comparatively. The survival rate of the PFP’s varies depending on the ceramic material used and the prostheses extension, no significant difference was observed in the relation between the ceramic material used and the connectors size; however, the greater the extension of the prosthesis, the higher must be the connector size. It was concluded that ceramic materials based on zirconia are the ones that have the longest survival. In addition, the main reasons that lead to decreased survival of PFP’s are secondary caries and connector fracture, however, more studies are needed to determine safely which materials and the extent of PFP’s are the most indicated. Descriptors: Ceramics, partial fixed prosthesis, survival rate. 1 Professor of the Dentistry course – DOCTUM, Specialist in Dental Prosthesis, M.Sc. in Dental Clinic – UFES. 2 Specialist in Implant Dentistry and Periodontics, M. in Dentistry with emphasis in Periodontics – UNG. 3 Professor of the Dentistry course – FAESA, Specialist in Prosthodontics, Orofacial Pain, Temporomandibular Dysfunction and Implant Dentistry, M.D. and Ph. 4 MSc and Doctoral Student in Dental Clinic, area of concentration Dental Prosthesis – FOP/UNICAMP. 5 Me. and Dr. in Dental Materials – FOP/UNICAMP.
