Removable Partial Denture Frameworks

The Perfect Combination of CAD/CAM and Alloy Expertise

Modellgussgerüste aus WIRONIUM® RP

The CAD/CAM processing solution: Selective Laser Melting (SLM)

  • 3D printing with metal powder – developed and patented by BEGO for the dental branch
  • CAD data is used to control a laser, which melts metallic powder layer by layer to build up the frameworks
  • Offers very good quality in the production of individual, complex metal frameworks

The alloy: WIRONIUM® RP

  • Non precious metal alloy for the additive production of removable partial denture (RPD) frameworks
  • Further development of the casting alloy WIRONIUM®, which has been proven millions of times
  • Specially developed for the digital production of dental RPD frameworks using the Selective Laser Melting process
  • Biocompatible and corrosion resistant
  • Approval as a class IIa** medical device is proof of our claim to comprehensively qualify our materials for dental use

Restorations are custom-made products in accordance with Directive 93/42/EEC. WIRONIUM® RP is a cobalt-based dental alloy and complies with ISO 22674 and ISO 9693-1. Please report all incidents occurring in connection with restorations made of WIRONIUM® RP to BEGO Medical GmbH and the responible authorities.
Metal dust is harmful to health. Grinding and blasting should be performed using an appropriate extraction system. Respiratory protection of type FFFP3 EN149 is recommended.
In the case of approximal or occlusal contact with other metals, electromechanically-related numbness may occur in very rare cases. There are no findings on the safety and effectiveness of treatment for children or pregnant or breastfeeding women. WIRONIUM® RP may disrupt the analysis of MRI exams and should be separated before such examinations.
Adverse effects
WIRONIUM® RP has no known adverse effects. However, individual reactions (e.g. allgergies or incompatibilities) to components of WIRONIUM® RP in very rare cases cannot be excluded. In such cases, Wironium RP restorations should no longer be used.
Application-related recommendations provided by us, whether given verbally, in writing or by wayof practical instructions, are based on our own experience and tests and may therefore only be regarded as general guidelines. Our products are subject to continuous development. Therefore, we reserve the right to make modifications in design and composition.
If any severe incidents should occur in relation to the use of WIRONIUM® RP, please notify BEGO Medical GmbH and the responsible authorities.


Real. Perfect. Fitting.

  • Industrial production process with heat treatment adapted to the alloy ensures an above-average fit of SLM-fabricated RPD frameworks for upper and lower jaws – even in complex cases

Real. Good. Activation.

  • High ductility of the material allows activation of the clamps as with cast components and thus a comfortable insertion and removal of the RPD
  • High fatigue strength of the clamps due to homogeneous and pore-free material structure

Real. Efficent. Solution.

  • High efficiency and design freedom through digitization of conventional workflows (CAD design and CAM production)
  • Sustainability: Significantly more resource-efficient work and lower costs compared to other manufacturing technologies such as milling

Real. Super. Shiny.

  • Excellent polishing properties, comparable to those of cast components
  • On request with high-gloss polish for minimal reworking in the laboratory

Highly polished or blasted – the choice is yours
