The accuracy comparison of 3D-printed post and core using castable resin and castable wax resin.

Purpose: The purpose of this research was to compare the accuracy of three-dimensionally (3D) printed post and core fabricated with two different materials: reinforced wax and castable resin. MATERIALS AND METHODS: Fifteen extracted single root central incisors were selected. Root canal treatment and tooth preparation for crown were performed on all teeth.

The Accuracy of Post and Core Fabricated with Digital Technology.

Purpose: To compare the accuracy of post and cores created with three different fabricating techniques: direct conventional, machine milling, and three-dimensional (3D) printing.

Materials And Methods: Thirteen extracted single root central incisors were selected. Root canal treatment and tooth preparation for crown were performed on all teeth.
