Clinical Performance and Patient Satisfaction of Cerasmart Versus Lithium Disilicate (E-max) Endocrowns

Plain-language summary

1. RATIONALE All-ceramic endocrowns are bonded to the tooth using adhesive resins creating strong bonds to the tooth structure resulting in strengthening effect and reducing the need for post and core. various CAD/CAM materials can be used for the fabrication of endocrowns including lithium-disilicate reinforced glass-ceramics, feldspathic ceramics, in ceram alumina and in ceram spinell as well as hybrid ceramics and composites. Fewer data are available on the clinical performance of the different materials used for endocrowns. With the rapid innovation in the dental restorative materials clinicians are sometimes confused when selecting the best restorative material to restore an endodontically treated tooth with an endocrown. This is due to lack of data with regard to clinical performance of these restorations as well as the degree of patient satisfaction. 2. OBJECTIVES P= Endodontically treated teeth indicated for endocrown I1= Feldspathic endocrown I2= Hybrid endocrown C= IPS e.max Endocrown O= Clinical performance Research question In patients with endodontically treated teeth requiring endocrown restorations, what are the clinical performance and the level of patient satisfaction of cerasmart endocrown versus lithium disilicate (e-max) ceramic endocrowns?
