CAD/CAM Technology – A Modern Day Tool

Many events have changed the practice of dentistry over the years, creating a highly efficient and much more comfortable visit for patients, with an increasingly more aesthetically pleasing outcome. Dentists and technicians alike have worked hard to improve various techniques and materials in their strive for excellence, aiding the continual development of the profession. Particularly within the areas of restorative and prosthetic dentistry, the industry has seen some huge advances in the last few decades.

For example, the humble crown has a fairly long history; the well known, all-porcelain ‘jacket’ crown (PJC) was first patented in 1889. As the name suggests, it consisted of rebuilding the tooth with a porcelain covering to create the restoration. Though improved over time, the PJC was used extensively well into the 1950s. [1]

The introduction of ‘porcelain-fused-to-metal’ in the1950s greatly improved the strength of crowns, with lost-wax fabricated metal copings addressing the issue of marginal fit.[2]

Many would now argue that one of the most influential developments in the history of dentistry has been the application of digital technology. Conceptualised in the 1970s by Francois Duret, computer-aided design (CAD) and manufacture (CAM) has totally transformed the way both dentists and technicians approach the creation and manufacture of restorative and prosthetic devices, especially single- or duel- tooth restorations.

The enhanced and refined CAD/CAM equipment available on the dental market today, present a wide range of benefits to both dentists and technicians in their every-day working lives. The latest impression scanning equipment produces crystal clear images in either 2D or 3D, ensuring optimal consistency and predictability and offering a level of detail and accuracy that otherwise would have been well beyond reach. Dental professionals can now create restorations of a high quality that fit the patient correctly first time ­– tolerances of within ± 25 µm now ensure a perfect fit, with no space between teeth, or between tooth preparation and restoration, both of which have the potential to cause infection or decay. The lack of metal content means that x-rays can penetrate the structure allowing dentists to keep track of potential decay. Add to this improved comfort, reduced intrusion and shorter assessment times, and it isn’t difficult to see why such procedures are so popular and encourage patient satisfaction.

Modern CAD/CAM technology is also designed to improve the professionals’ workflow, as well as enhancing the patient experience. Special features such as high-angulation scanners and light guidance systems enable professionals to capture the images they need with little preparation. Mass production with individual customisations is another advantage of digital impressioning, as each restoration can be reviewed and adjusted to meet the necessary requirements in a fast and cost-efficient way.

The most effective CAD/CAM systems can then be fully integrated into the practice management software, dramatically increasing accessibility and efficiency throughout the practice or laboratory. Such programmes also facilitate communication between the dentist and technician, as impression scans and images can easily and securely be sent between the two, for truly successful collaborative cases.

With the equipment to scan, mill, design and place restorations all in one place, modern CAD/CAM technology ultimately offers dentists a choice – they can either create restorations chairside for a quick and efficient treatment process, or they can send their images straight to their technician for manufacture in the lab. This flexibility ensures all dentists can work they way that best suits them and their patient. From technicians’ points of view, the easy-to-use equipment allows them to provide a broader range of services, without excessive retraining costs.

However the CAD/CAM equipment is used, it is a highly effective way of developing the business and driving the practice or laboratory forward. Systems such as the CS Solutions from Carestream Dental, bring all the facets of scanning, designing, milling and placing restorations into one portfolio. Available as stand-alone technologies or as a fully integrated solution, the equipment will help streamline your processes and ensure your whole team works as efficiently as possible.

Compact and easy to use, the impression scanners require no trolley so are easily portable around the premises, and USB connections ensure images and data can be transferred to any computer or workstation. Ergonomic designs and simple interfaces further increase ease of use, and professionals can create superior restorations in a matter of minutes.

Only a few years ago, the idea of ‘digital dentistry’ was very much something of the future. Well that time has now come, and CAD/CAM technology is one of the most effective tools to drive both dental practices and laboratories forward. Are you a part of the revolution yet?
