So what is digital dentistry? This means any type of technology or device that uses digital/computer based components, comapred to the traditional methods that used mechanical or electric workings alone.
CAD/CAM
One of the most note-worthy pices of technology that has grown in dentistry in recent years is CAD/CAM machinery. This is the method of applying Computer Aided Design or Computer Aided Manufacturing to assist with dental treatments. Most commonly this technology is used in tooth restoration for treatments such as dental crowns, veneers and dental implants.
This technology was invented in the 1980s, but was seen simply as a novelty piece of equipment due to the fact tht it was so large and difficult to operate. However, in the last 15 years, as technology grew, CAD/CAM design became more streamlined, efficient and easier to operate. CAD/CAM technology is growing in popularity as the machinery allows for a more natural looking tooth which not only is more durable but also fits the mouth better.
How does CAD/CAM work?
1. CAD works by designing restorations on the computer screen. A sharp image is picked up of the pateient's mouth by using an optical scanner. Currently the newest piece of scanning equipment is the CERC omnicam 4.2 which can take an exact replica of the patient's mouth. Previously, optical scanners wer not as powerful and the patient would have to have an unpleasent tasting spray coated on their mouth to ensure the camera picked up more detail. This CERC omnicam 4.2 eliminates the need for this discomfort. What's more, using a digital optical scanner means patients will not have to sit with impression materials in their mouths as was the traditional method.7
2. CAD technology is then used to create the restoration. This can be done in-house if the surgery has invested in the CAM software, or sent away to and external lab. If the technology is in house, the restoration can be completed within a number of hours.
3. The restoration is manufactured using milling or printing on seperate CAM machinery.
Benefits of CAD/CAM
CAD/CAM technology is ideal for patients who are nervous about visiting the dentist, they are not subjected to the same discomfort that traditional impressions are associated with.
Patients who suffer anxiety will not have to revisit the dentist multiple times if their practice has their own CAM software
The process is mproved in time and efficiency
The restorations have improved accuracy, there will not be gaps between crowns, veneers etc. and surrounding teeth
CAD/CAM allows for a high level of predictability in the results with crowns, veneers and tooth impants, giving dentists and patients peace of mind.
What does the future of dentistry look like?
Some practices are hesitant in taking up this technology because those more established and mature practices who can afford the expenditure on the new technology simply do not feel comfortable using it whereas the younger generation who are at ease with digital technology don’t have the funds available to invest in production facilities.
Thanks to technical advances, the future of dentistry is looking bright - and digital. Once these advances were only available to the minorty of practices, but as with all technology once the innovation has been adopted by a few and production grows, the cost comes down. Patients who have their restorations created using CAD/CAM software have a greater level of care than those who undergo traditional methods. It's advised that all practices who have the funds to invest in this growing technology does so, so as not to leave your practice out of touch in coming years.
