Vertex-Dental BV presenteert Class IIa NextDent materialen voor 3D printing

7 april 2016 -  Vertex-Dental BV heeft dental materialen voor 3D printing aangekondigd. Het hierna volgende persbericht is verschenen:

Vertex-Dental BV, a leading developer and manufacturer of biocompatible 3D printing materials in dental, announces the introduction of NextDent 3D printing materials with a Class IIa certification according the Medical Device Directive 93/42/EC. Class IIa certification of these materials, makes it possible, for the first time in dental history, to use 3D-printing for multiple long term applications. Splints, denture bases, crowns and bridges can now be manufactured for long-term use in the oral cavity, using 3D printing technology. This creates the foundation for a breakthrough of 3D printing technologies in dentistry.

Milling has become an established method for the production of all-ceramic restorations. However, the subtractive technology has failed to replace traditional production methods for applications such as splints and dentures. Here, 3D printing has already proven its worth as an additive procedure with virtually no geometrical restrictions and reduced material consumption. The limitation: So far, materials were certified for temporary use only.

New materials, new opportunities
The launch of the biocompatibele CE-certified Class IIa NextDent materials changes this situation. With NextDent Ortho Rigid, it is possible to produce splints for long-term use in the patient’s mouth. The material NextDent Base was specifically developed for the printing of denture bases. Opposed to traditional PMMA denture base materials, it offers an extremely low shrinkage, contributing to a better fit.



Last but not least, Vertex-Dental BV offers a tooth-colored Class IIa material - NextDent's Class I 3D printing materials for the production of surgical guides, individual impression trays and indirect bonding trays. And the other non-classified Nexdent® materials: Model, Model Ortho, Cast and Gingiva Mask. The NextDent LC-3DPrint Box, a UV light box for post curing of the resins, is available as well. Post-curing is an UV light treatment to ensure that NextDent materials obtain full polymer conversion, through this, the residual monomer is reduced to a minimum and the highest mechanical properties are obtained. This procedure is a necessary step to produce a biocompatible end-product.

All materials are compatible with DLP/SLA based printers with a wavelength range of 365 to 405 nm. In order to ensure a predictable output, Vertex-Dental BV collaborates with several 3D printer manufacturers to determine the ideal parameters for every material and machine combination.
