A patient presented to our rooms with discolored anterior teeth.

Investigation revealed that the teeth had fillings on many surfaces. The gums were healthy.Xrays did not show any periodontal disease or any other disease.

The teeth were prepared in one sitting. A precise dental impression was taken and sent to the laboratory. In the mean time the patient wore a set of temporary crowns that were made at the chairside.

It was decided to use a zirconium core to mask out the dark inner colour of the teeth. Porcelain was then added to the zirconium. The porcelain-zirconium crowns offered increased strength and beauty at the same time. The laboratory fabrication took 5 days.

On the sixth day the temporary crowns were removed and the new porcelain-zirconium crowns cemented.
