DENTAL PROSTHESIS MANUFACTURING
WITH COMPUTER-AIDED DESIGN
In the past, the production of dental prostheses was done analogically. Although traditional pressing and casting techniques are still used today, the manufacturing of dental prostheses has largely been transformed into a digital workflow in recent years. We, as a service provider, as well as dental laboratories and dentists, benefit from this advancement.
3 PHASES IN THE CAD/CAM PROCESS
The CAD/CAM process involves three steps: data acquisition, data processing, and product manufacturing. The final step can be either additive or subtractive.
Data Acquisition (CAI)
To digitally capture the oral situation, the necessary data is either collected intraorally or a existing gypsum model is scanned and converted into a digital format.
Data Processing (CAD)
Data processing utilizes design software that uses the available data to create the desired dental prosthesis. The software is capable of virtually testing the functionality of the designed prosthesis. If the simulation provides satisfactory results, the data is then exported for manufacturing.
Manufacturing (CAM)
Depending on the project, Computer-Aided Manufacturing (CAM) can involve either subtractive or additive processes. The dental prosthesis is thus either milled, produced using laser technology, or created through 3D printing.
Applicable Materials / Materials
The material used in the CAD/CAM process depends on the indication and the professional assessment of the dental technician.
