Root canal restoration treatment is considered a popular practice in the medical and dentistry field as it keeps the remaining healthy part of the damaged/infected tooth and restores its function. It is important to plan the right restoration tooth material to avoid any infection or leakage happened on the tooth. Before this final project conducted and written, a research on ETT with zirconium endocrown and overlay was already conducted. The research [1] concluded that a zirconium endocrown of a first molar ETT can withstand a 720N vertical load and the critical concentrated force on the model will remains on the CEJ part of the remaining tooth. CEJ or Cemento-enamel junction is the area of union of the cementum and enamel at the cervical region of tooth. It represents the limit between the crown and root surface. The current research was done by performing computational simulation using the finite element analysis tools. Two types of load were simulated: a 720N vertical load with the direction parallel to the tooth’s length axis and a 200N load with 45? angle from the tooth’s length axis. The model used are an endodontically treated tooth (ETT) with onlay restoration and an ETT with endocrown restoration. In this research, two types of luting cement will be used: Variolink Esthetic LC and RelyX Ultimate, while using a ceromer called ceramage for the crown restoration. The simulation shows the effect of luting cement application to Endodontically Treated Teeth based on the crown restoration. In the case of ETT with CEC and onlay restoration, it is shown that RelyX Ultimate strengthens both dentine and enamel of ETT in comparison to Variolink E application For ETT with endocrown restoration, Variolink protects the dentine and enamel of ETT better in comparison to dentine and enamel of ETT with RelyX Ultimate luting cement. This conclusion is taken for the dentine and enamel of these parts experiences smaller stresses compared to the comparison dentine and enamel.
