Summary

Use chairside Computer-Aided Design \& Computer-Aided Manufacturing(CAD/CAM) system (computer aided design / manufacture), using glass ceramic zirconia enhanced lithium silicate glass ceramics (VITA, SUPRINITY, VS) material, compare the difference of firmness, comfort and durability between two kinds of root canal restoration methods:endocrown and 90° shoulder endocrown. Objective to establish the optimal method and material for the restoration of the teeth with root canal therapy.
