CAD/CAM has gone a long way towards making dental fabrication processes more efficient. Explore this in-depth guide where we break down all you need to know about dental CAD/CAM.
Technology has played an important role in the evolution of dentistry by bettering work conditions both in dental offices and in dental laboratories. And one notable advancement is CAD/CAM dentistry. This simply refers to the digital design of dental fixtures, crowns, and more using CAD, and the fabrication of those products using CAM.
With the accuracy and reliability of modern fabrication processes, not to mention the accuracy and efficiency of 3D scanning, dental object fabrication became a lot more potent.
Dig into this detailed guide to dental CAD/CAM.
CAD/CAM dentistry, as its name implies, is a discipline of dentistry which use CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing) systems to improve the design and fabrication of dental restorations.
It can be used in the design and construction of veneers, implant abutments, crowns, inlays, onlays, fixed partial dentures and full-mouth reconstruction. Also, we can use CAD/CAM in orthodontics. But in dentistry specifically, it was only used for the first time a decade after its creation. In the 1960s, this technology was used in the aircraft and automotive industries.
All CAD/CAM systems consist of three components:
1. Computerized Surface Digitization Using Scanners.
Geometry is transformed into digital data which can be processed by a computer. The data acquisition involves making an optical impression of the preparation. We can do so with the help of:
A scanner in dentistry refers to a data collection device which measures three dimensional jaw and tooth structures to transform them into digital data sets.
There are two types:
Data is obtained from the scanning process and, depending on the application, a data set is produced to fabricate the product. We can store the data of the construction in various data formats, but the standard is often STL files.
With CAD software, we can provide various dental restoration designs to the CAM unit.
A production technology which transforms the data set into the desired product through milling. We can differentiate the processing devices according to:
The production concepts depend on the location of the components of the CAD/CAM systems:
Now we can show you the materials which we can use on dental CAD/CAM devices:
Firstly, the process depends on the system used. There are some systems which provide you same-day, in-office restorations, and we’re going to focus on this possibility due to its many advantages.
According to Davidowitz and Kotick: “Dentists who wish to begin providing same-day restorations can purchase a complete CAD/CAM system at a cost of approximately $90,000 to $112,000. A lower-cost option is to purchase a digital scanner only; prices for these range from about $24,000 to $41,000. Each scan costs between $16 and $35.
Using a complete system has the potential to reduce costs related to impression material, provisional crowns, time in the office, and laboratory bills. Dr. Parag Kachalia estimated that dentists who switch to office CAD/CAM systems can reduce their laboratory bill by 60% to 70%.”
As you can see, dental CAD/CAM is a sector ripe with innovation. This provides dentists and patients a better experience in terms of quality, speed, ease of use, precision, and economy.
