Vertex-Dental BV has announced its new Class IIa NextDent biocompatible dental materials for 3D printing

Netherlands-based Vertex-Dental BV, a developer and manufacturer of biocompatible 3D printing dental materials, has announced its new NextDent 3D printing materials with a Class IIa certification according to 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 long-term applications. Splints, denture bases, crowns and bridges can now be manufactured for long-term use in the oral cavity. This creates what Vertex-Dental BV describes as “the foundation for a breakthrough of 3D printing technologies in dentistry”.

A spokesperson said, “Milling has become an established method for the production of all-ceramic restorations. However, 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 biocompatible CE-certified Class IIa NextDent materials changes this situation. NextDent Ortho Rigid makes it possible to produce splints for long-term use in patients’ mouths.
• NextDent Base was specifically developed for the printing of denture bases. Unlike traditional PMMA denture base materials, the manufacturer claims it offers “extremely low shrinkage”, contributing to a better fit.
• NextDent C&B is a tooth-coloured Class IIa material for the production of crowns and up to three-unit bridges for mid-term solutions.

Complete portfolio

The three new materials complement the existing portfolio of NextDent’s Class I, 3D printing materials for the production of surgical guides, individual impression trays and indirect bonding trays, as well as the other non-classified Nexdent materials: Model, Model Ortho, Cast and Gingiva Mask. The company also manufactures the NextDent LC-3DPrint Box, a UV light box for post curing the resins (below).

The Vertex-Dental spokesperson explaines, “Post-curing is a UV light treatment designed to ensure NextDent materials obtain full polymer conversion. Through this process residual monomer is reduced to a minimum and the highest mechanical properties are obtained. This procedure is a necessary step towards producing 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.
