Many CAD/CAM systems of partner companies were validated for the processing of VITA CAD/CAM materials by VITA Zahnfabrik. In the context of validation, the respective material-specific parameters are stored in the software so that the material and fabrication unit are ideally adjusted to each other in the production process.
In addition to VITA CAD/CAM blanks with system-specific holder systems (e.g., for CEREC/inLab, Ceramill Motion 2, KaVo ARCTICA/Everest Engine), many VITA materials are also available today as UNIVERSAL SOLUTIONS. These are equipped with a universal holder system or are offered as a universal disc geometry. Solutions for the following dental CAD/CAM systems are available:
•CORiTEC series (imes-icore GmbH)*
•DWX series (Roland Digital Group)*
•CS 3000 (Carestream Inc.)*
•K-/S model (vhf camfacture AG)*
•ULTRASONIC series (SAUER GmbH / DMG Mori Seiki AG)**
•RXD series (Röders GmbH)**
The VITA blanks can be used in the fabrication unit with a universal holder system in the proven manner using an adapter. Computer-supported fabrication can therefore be immediately implemented without the necessity of learning new technologies or specific procedures.
*) The CAD/CAM system partner has been validated by VITA Zahnfabrik for processing specific VITA CAD/CAM materials.
**) Processing of specific CAD/CAM materials is recommended by VITA Zahnfabrik for this CAD/CAM system or line of systems.
imes-icore GmbH is a validated CAD/CAM system partner of VITA Zahnfabrik (Eiterfeld, Germany). For processing with the CORiTEC system, VITA Zahnfabrik (Bad Säckingen, Germany) now offers material blanks with a universal holder system and in a universal disc geometry. How VITA materials have been proven in processing with this system so far, and how system parameters adjusted specifically to the material prove advantageous in daily laboratory work are reported in the following interview with MDT Reinhard Sroka.
DV: Which VITA materials have you already processed with your CORiTEC system, and how do you evaluate the results achieved with regard to quality, fit and other parameters?
MDT Reinhard Sroka: With our fabrication unit, the CORiTEC 550i, we regularly process the zirconia VITA YZ Disc, among others. It can be extremely efficient. For example, we can mill with a high machine throughput, even while maintaining the highest quality standards. The same applies for VITA ENAMIC, which especially exhibits a very good edge quality. Our first experiences with VITA SUPRINITY show that this material can be processed more easily and with more stable edges than other materials in its class.
DV: Is it important for you that the CORiTEC unit has been validated for the processing of selected VITA CAD/CAM materials by VITA Zahnfabrik, and if yes, why?
MDT Reinhard Sroka: Validation is meaningful since there is a material-side testing of the processing templates stored in the CAM software and of the entire workflow through comprehensive tests. In this way, we have received confirmation that the desired quality standards are being achieved. This fact can be successfully communicated by the quality seal stating that it is a "VITA-authorized milling center" and also helps to keep existing customers over the long term as well as to win new customers.
DV: For which indications do you prefer to use which VITA materials, and why?
MDT Reinhard Sroka: We use the available VITA YZ in different variants because of its high reliability as a standard material in the the fabrication of crowns and bridges (frameworks). VITA ENAMIC is used for monolithic crowns as well as inlays and onlays - the hybrid ceramic is pleasing because of its tooth-like properties and is growing in favor. We regard VITA SUPRINITY as good for restorations in the anterior tooth region (e.g., veneers), because of its good optical properties and the optimized edge stability.
DV: What new opportunities do you see in the processing of new materials such as VITA ENAMIC or VITA SUPRINITY?
MDT Reinhard Sroka: In my estimation, there are new ways to treat patient groups for whom traditional ceramics have reached their limits, especially with VITA ENAMIC. This is due to the dentin-like elasticity of the material, which works especially well for restorations on implants or in patients with parafunctions.
