CAD/CAM in Dentistry


Computer-aided design (CAD) and computer-aided manufacturing
(CAM) are terms describing software that make it possible for dentists
to perform complex procedures faster, more easily and more

CAD/CAM technology constructs restorations, like crowns, veneers,
inlays, on-lays and bridges, from a single block of ceramics, which
makes the final product more precise compared to traditional
fabrication methods.

Custom 3-D images of your prepared tooth or teeth are created by
digitally scanning your impressions. These scans are then used to
produce a virtual design for the restorative device, which is then sent to
connect milling equipment digitally.

Software places margin line with high precision and automatically creates a highly aesthetic tooth


Whether inlays, on-lays, crowns or veneers – you can create full-contour individual tooth restorations.

Advantages of using CAD/CAM in Dentistry

The materials are aesthetically pleasing and durable; there is increased efficiency in laboratory processing; quick fabrication of the restoration; and quality control of restorations such as fit, mechanical durability and predictability. These advantages will ultimately benefit our patients.

What is a dental crown?

A dental crown is a tooth-shaped cover which fits over the existing structure of your natural tooth to protect and restore the tooth’s function.

Crowns can be used:

  • After root canal treatment to help strengthen the tooth
  • To strengthen teeth which have been weakened by decay or a large filling
  • To protect fractured, cracked and worn teeth
  • To cover the abutment after an implant has been placed in the bone and gum, for an undetectable, natural finish
  • To aesthetically improve the shape, alignment and shade of a tooth

What types of materials are used to fabricate dental crowns?

Crowns are made using the following materials:

  • All-metal. Often gold or tooth-coloured crowns such as porcelain fused
  • Metal. Usually gold or a gold alloy underneath a ceramic outer layer
  • Full ceramic porcelain or composite. Plastic with glass particles embedded. 

Our doctors will discuss the benefits of the various crowns with the patient and recommend the most suitable option. 

What types of crowns are commonly fabricated at DP Dental?

At DP Dental, we are committed to providing the highest quality dental care with our highly specialised dental team and the aid of state-of-the-art technologies. Our doctors are certified practitioners of the revolutionary CEREC – One-Visit Ceramic Restoration technology.

With this technology, patients only have to visit our doctors once and walk out with a new, natural, permanently fixed ceramic (porcelain) crown. There is no more waiting for laboratories to hand-craft each crown, no more second visits to fix the crown, and no more temporary crowns.

Our doctors at DP Dental will shape your tooth, scan it with the CEREC machine, and mill it in our in-house laboratory and cement it onto your tooth on the same day. The result is a highly accurate, precise, and natural-looking crown fitted on the same day.

How does the CEREC technology work?

First, our doctors numb the tooth and the surrounding gum with local anaesthesia, then the tooth is shaped, creating a cylindrical shape onto which the crown will be cemented.

At this point, instead of using “dental putty” to take an impression of your tooth, a digital camera is used to scan your tooth. This video is then converted into a 3D computerised model of your tooth, which is used as a guide to design your new restoration.

Once your dentist is happy with the newly designed tooth, this data is sent to an on-site milling machine, which fabricates your new tooth from a high-quality ceramic block.

Matching shade and fit

The ceramic blocks come in a wide variety of shades and colours, and your tooth will be selected to match your surrounding teeth. Once the crown or veneer has been milled, our doctor may choose to characterize it by glazing to match your surrounding teeth. Your new restoration will then be cemented into place onto your prepared tooth.

Our doctor will help you try in your new crown, making sure that it fits correctly and that you are happy with the appearance. The crown will then be permanently cemented in place. The bite is checked carefully, and minor adjustments are made if necessary.
