Contemporary all-ceramic systems allow us greater management of light and color to mimic the natural dentition. There are various common colors present in the adjacent prepared teeth. These different backgrounds often influence the final shade of the cemented restoration, which complicates the crown fabrication. This difficulty becomes more critical when restoring a single anterior tooth. Different ambient light conditions may alter the observed appearance of the restoration to the patient, dentist, and technician. This presentation explains how to select an all-ceramic system for different clinical situations. The material selection is based primarily on the material's opacity and/or translucency. Guidelines for communication between the dentist and technician are also discussed.
