Objectives: The aim of this thesis is to determine whether lithium disilicate glass ceramic crowns or zirconium oxide crowns are more suitable choice for the restoration of anterior and posterior teeth. To that end the survival rate and mechanical properties of the two materials will be compared, and the options for restoration will be discussed.

Materials and Methods: An online search over PubMed was done for the mechanical properties of the lithium disilicate and zirconia crowns and FPD’s for anterior and posterior region. The search included studies done in English from 2010 till 2019. A total of 51 papers were selected from 2544 papers found. The studies which included restorations like fully contoured, monolithic or bi-layered lithium disilicate or zirconia crowns and zirconia framework, partial coverage crowns, veneers, inlay/on-lay restorations were also used for this study. The articles about chairside restorations were excluded.

Results: In this study, the flexural strength of lithium disilicate material has been found to be on an average as 369.75 +/- 42 MPa with the fracture toughness of 2.044 MPa x m0.5 as compared to zirconia oxide which has an average of 1004 MPa flexural strength and Fracture strength of 6.9 MPa x m0.5.

Conclusion: It was concluded that Lithium disilicate crowns being aesthetically pleasing and possessing flexural and fatigue strength of over 290 - 460 MPa therefore, can be used to restore anterior teeth. On the other hand, Zirconia crowns consist of increased strength properties, over 1000 MPa, can withstand high stresses in load bearing areas, is a good option for the fabrication of the posterior restorations.
