Introduction
Very often, we find that there are people who go through life never smiling because they are very conscious of how they look, particularly how their teeth look.
Recently we had a visit from a young woman who is very successful in her career. However she was quite conscious of her smile. This leads to lack of confidence in her workplace and in social functions.
Upon examination we found that she had perfect dental health! However she was born with commonly known as "peg upper lateral teeth". They are popularly known as this, as the shape of these teeth resembles cloth pegs. The result was abnormally narrow teeth, as seen below:
So a treatment plan was formulated for the above patient. It was decided that four zircon crowns were to be done to rectify the size and shape discrepancies of the anterior front teeth.
The teeth were carefully reshaped and an impression was done and sent to our German technician.
The preparation was scanned and milled to our specifications. Within a few days we had a new smile for the above patient, as seen below:
The Advantages of Zircon Crowns over conventional metal fused to porcelain crown.
Zircon crown became popular in the last five years due to a breakthrough in milling technology, CADCAM software and the internet.
Today it is possible to mill crowns from block of zircons. They are accurate enough to fill in the shape that was created by the dentist. CAD CAM software also made it possible for dentists to design and specify shape and thickness of these crowns before they are manufactured. The internet is used to send these data to milling centres anywhere in the world. However, skilled technicians and the dental surgeon are still required to give excellent finishing and delivery of these Zircon crowns.
The advantages of these crowns over the normal porcelain crowns are obvious, in the way of aesthetics. Zircon crowns give a natural hue to the tooth better than any metal fused to porcelain can.
The preparation of zircons are also more conservative, this means less tooth substance is taken away in the process of crown making.
