The aim of this study was to evaluate the effects of two endocrown designs and computer aided design/manufacturing (CAD/CAM) materials on stress distribution and failure probability of restorations applied to severely damaged endodontically treated maxillary first premolar tooth (MFP).
Two types of designs without and with 3 mm intraradicular extensions, endocrown (E) and modified endocrown (ME), were modeled on a 3D Finite element (FE) model of the MFP.
Vitablocks Mark II (VMII), Vita Enamic (VE), and Lava Ultimate (LU) CAD/CAM materials were used for each type of design.
von Mises and maximum principle values were evaluated and the Weibull function was incorporated with FE analysis to calculate the long term failure probability.
Regarding the stresses that occurred in enamel, for each group of material, ME restoration design transmitted less stress than endocrown.
During normal occlusal function, the overall failure probability was minimum for ME with VMII.
ME restoration design with VE was the best restorative option for premolar teeth with extensive loss of coronal structure under high occlusal loads.
Therefore, ME design could be a favorable treatment option for MFPs with missing palatal cusp.
Among the CAD/CAM materials tested, VMII and VE were found to be more tooth-friendly than LU.
