In the past, the traditional methods for making tooth-colored restorations,
crowns, and veneers involved a series of dental appointments and final
fabrication of the restoration by a dental laboratory. Today CAD/CAM allows
our Houston dentist to custom-fabricate any of these in the office and
cement them in place - all in a single appointment. 
The first step in using dental CAD/CAM is tooth preparation. The second step
involves taking an impression, not by pressing a soft material over the tooth,
but by taking a picture with a special camera that sends the prepared tooth's
exact dimensions into a computer.
The restoration is next designed with the aid of a computer, and then your
dentist selects a material that is colored to match your specific tooth.
The material is then placed into a miniature milling machine. In just a
few minutes it produces a precise, custom-fitting restoration.
Finally, the new restoration is test-fitted, color adjusted, and bonded
in place. After your bite and fit are checked, you'll have a new, CAD/CAM
restoration - in just one appointment.
