Dentists have been providing esthetic and pleasing solutions for years in the form of caps and veneers to cover, protect or beautify a tooth. On the face of it, that seems simple enough. The process involves shaping the tooth, taking a mould and sending it to a lab. A few days later your cap is ready to fit. So what is the problem? Here it is:
From the process of the moulding to the finish there is many a slip between the cup and the lip, and several errors can creep in.

The major problems you can find in these caps and bridges are that they could have one or all of these problems:

  • A cap fitting short of the gum line causing a ledge. You can feel this edge with your nail and worse, food can accumulate in this region where your cap meets the gum. In dental terms, this is called a “short margin”. As the days go by, given the unhygienic nature of the problems the gum responds by receding further away due to irritation.
  • The cap fits loosely on the tooth depending on the cement inside to hold it. When the cement dissolves, your cap could fall out.
  • The shape of your cap could be faulty as it is visualized by the laboratory technician on whose skill and experience the final result is dependent.
  • The colour of your cap matching your teeth may leave much to be desired.
  • After sometime decay can start to set in under the gum line causing pain and very often, a new infection.

The ubiquitous computer has invaded medicine and the world is today a different place. When small gaps make a big difference, the accuracy of the computer is unparalleled. The computer designs your cap decides where the margin of your tooth is lying and shapes the inner structure to provide the needed strength and accuracy.

Today CAD-CAM is the new terminology for the new technology Computer Aided Design – computer aided milling. In this system a dentist prepares your tooth and takes an impression, or a mould. The model is created from this and a scanner reads the finish line, the shape and all the other details.
