Introduction The objective of this case series report is color matching of the central incisors all-ceramic crowns and determine the color difference between those crowns and contralateral or neighboring intact natural incisor using the ΔEab value from CIELab formula. Case Report The subject of this color assessment was all-ceramic crowns for central incisors for three young female patients. The intact natural incisors were used as the target shade for the all-ceramic crown. After tooth preparation and intraoral scan, everything was done at once, regarding the design of restoration and model. For these cases, we used Ivoclar ZirCAD PRIME multi A1 (Ivoclar, Schaan, Liechtenstein) block. For proper shade mapping polarized picture with grey card for digital calibration is necessary as well as one standard picture for mapping the color effects. For tooth color mapping we used the eLAB software (eLAB Prime, Freiburg im Breisgau, Germany). Highest ΔEab value for all three cases was 2.7 or less, which indicates that the color is clinically acceptable, considering acceptability threshold value of less than 2.7 (three-year follow-up confirmed acceptable color appearance. Conclusion Following recommended protocol based on the eLAB software software (eLAB Prime), clinically acceptable color of the all-ceramic crown were obtained.
