case_images: On examination it was found that central incisor was endodontically treated and crown was dislodged (Figure 2(A)). The pattern was attached with sprue wax (Cercon Wax, Dentsply) to the respective holder (Figure 2(B)) and sprayed with scan spray (Cercon, Dentsply, Germany) for scanning for copy milling. After milling, zirconia post and core was separated from blank with straight fissure bur and sintered in Cercon furnace (Figure 2(C)). Paul, Minn) according to manufacturer instructions (Figure 2(D)); margins of the preparation were refined for central incisor as necessary for all-ceramic restorations. Paul, Minn) (Figure 2(E)).
