Technologies and materials ideally matched
In 2014, Core3dcentres International were certified by VITA as the first authorized milling center worldwide. Since then, Core3dcentres milling centers around the world have processed VITA CAD/CAM materials according to validated quality standards. With the validation of software and hardware, we are pursuing the goal of matching production technologies ideally to each of the materials used. MDT Sebastiaan Cornelissen, CEO of Core3dcentres International (Maartensdijk, Netherlands), reports in the following interview on his experiences regarding the processing of VITA CAD/CAM materials.
DV: Why is a fine attunement of production technology and materials so important?
MDT Sebastiaan Cornelissen: Each material has totally specific properties. For optimal production results and flawless production processes, a fine attunement is absolutely necessary.
DV: In what form could VITA support you in the validation process in order to develop ideally matched processing strategies for the respective materials?
MDT Sebastiaan Cornelissen: VITA has invested much time and money in its own knowledge base: specialized technicians, comprehensive CNC knowledge, specific test protocols for the validation and many other things. As a result, the development of attuned processing strategies in the milling center can be realized in a very short time.
DV: What advantages does the milling center have from a validation, and to what extent do your customers also profit from this?
MDT Sebastiaan Cornelissen: The validation guarantees coor dination between material manufacturers and the milling center, and provides an up to 100 percent adapted technique and workflow, highest accuracy of fit, material safety, etc. in the result.
DV: Which CAD/CAM systems do you work with, and which VITA materials do you prefer to use today?
MDT Sebastiaan Cornelissen: We work with machines from DMG MORI (Winterthur, Switzerland) and imes- core (Eiterfeld, Germany) and the CAM software hyperDENT (FOLLOWME!, Munich, Germany) and the CAD software from 3Shape (Copenhagen, Denmark). VITA ENAMIC and VITA glass ceramics, among others, are processed with these technologies.
DV: What VITA materials, in your opinion, have especially advantageous properties and how can you and your customers profit from this?
MDT Sebastiaan Cornelissen: We have VITA ENAMIC – the only genuine CAD/CAM hybrid ceramic on the market – to thank for our enormous growth. CAD/CAM-manufactured VITA ENAMIC restorations are fixed adhesively, according to the same protocol as for feldspar ceramics. VITA ENAMIC can also be milled to be extremely thin and is ideal for non-prep restorations such as tabletops.
DV: What trends and developments do you see for the next five years for CAD/CAM materials and manufacturing technologies?
MDT Sebastiaan Cornelissen: Blanks with integrated shade gradient for monolithic restorations become more important. The milling and grinding technology remains, in our opinion, the fastest and most economical production path for the foreseeable future.
Our thanks to the dentist Dr. Sjoerd Smeekens from the Kliniek voor Reconstructieve Tandheelkunde (Beuningen, Netherlands) for the great collaboration.
