The finished crown matches the dentist's and patient's expectations regarding function. However, it does does not harmonize with the adjacent teeth in situ. This discrepancy is often caused by incorrect tooth shade selection. Poor lighting conditions or other influencing factors can falsify the comparison of the tooth with the shade tab.

Digital shade measurement systems such as the VITA Easyshade offer a remedy to this problem. The device is referred to as a spectrophotometer and records the shade information contained within the (dentin) core of the tooth, thus determining the correct tooth shade independently of any existing surface discolorations and biofilms. The VITA Easyshade's digital measurement system utilizes the constant a white light LED to accurately illuminate the tooth, and a fiber optic system to absorb and analyze the light scattered by the tooth. The microprocessor-controlled evaluation of the measurement results is based on an artificial intelligence procedure and accesses the shade information of thousands of natural teeth. The result is reliable information on the patient's tooth shade.

Initial situation / Preparation for the manufacture of the new crown.

This shows Urszula Młynarska manufacturing the crown. She built up the crown by applying the veneering material VITA VMK Master to a metal substructure. The extended standard layering technique was then augmented in the enamel area with Opal Transparent OT1.

The photo shows the completed crown in situ after the bisque try-in, small corrections to the contour and glaze firing with VITA AKZENT Plus. The result leaves nothing to be desired. Patient, dentist and Urszula Młynarska are all delighted with the result.
