Invitro Fracture Resistance and Marginal Accuracy of Zirconia Inlay-retained Fixed Partial Denture: A Systematic Review

Objectives: To determine the fracture resistance and marginal accuracy of Inlay-Retained Fixed Partial Denture (IRFPD) fabricated from monolithic zirconia to determine whether it can replace full coverage zirconia restoration. Methods: Search was made in three databases including Pubmed, ScienceDirect and Cochrane databases, the terms yttria stabilized tetragonal zirconia, inlay, full coverage and fixed partial denture were used, title and abstract were screened; according to the exclusion and inclusion criteria articles which did not follow the inclusion criteria were excluded. Included papers are then read carefully for a second stage filter, this was followed by manual searching. Results: The search resulted in 5 included papers, four papers concerning the fracture resistance of Inlay-Retained Fixed Partial Denture and one determining the fracture resistance of full coverage three unit fixed partial denture. No papers were found studying the marginal accuracy of monolithic zirconia Inlay-Retained Or Full Coverage Fixed Partial Denture. From the included studies zirconia Inlay-Retained Fixed Partial Denture can successfully replace zirconia full coverage fixed partial denture in terms of fracture resistance.
