remanium® star powder

remanium® star powder & rematitan® powder
An alloy rediscovered

     

Laser melting with the best materials.

remanium star® powder is the clinically proven EMF alloy for the production of crowns, bridges and model castings in the additive laser melting process. Compatible with all market-leading laser melting systems. You too can discover the star among alloys!

Dentaurum has years of experience in the field of laser melting, and is therefore the ideal contact for this process in the dental industry.

Product advantages

  • Decades of experience in powder metallurgy in dental prosthetics and orthodontics
  • Ideal grain size distribution for many laser melting units and areas of application
  • Same composition as the proven remanium® star alloys for milling and casting
  • Perfect suitability for partial dentures with scientifically tested properties for clasp constructions
  • Modified CTE value ensures very good ceramic bonding for crowns and bridges
  • All prosthetic work can be produced simultaneously on one build plate
  • Smooth and dense framework surfaces thanks to optimized grain size selection
  • Optimum stress relief thanks to concrete recommendations for heat treatment

 

Simple and efficient heat treatment.

Dental restorations made with remanium® star powder can now be annealed free of tension in approx. 1 hour without shielding gas or special furnaces. This combines the proven product quality with high efficiency and flexibility.

remanium® star powder for partial dentures.

remanium® star powder is highly suited for the production of clasp-retained dentures, delivering results comparable to cast constructions. This was also scientifically proven by a continuous stress test:

Conclusion of study by the University of Tübingen, Germany:

"...It was possible to show that the retention forces of dental clasps, manufactured by selective laser beam melting, are comparable with the forces of precision-cast clasps..."

*Direct Metal Laser Melting versus dental investment casting - retention forces of ESG clasps over a simulated wear time of ten years.

Retention forces of one-piece cast clasps over a simulated time in-situ of ten years.

Videos remanium® star powder

remanium® star and rematitan® powder for the crown and bridge technique

remanium® and rematitan® are world-renowned brands. We have been manufacturing and distributing CoCr as casting alloys since 1935 and as powder for the laser melting technology since 2009. Building on this wealth of experience, we have developed remanium® star and rematitan® powder. The extremely fine powders have an ideal gran size distribution of 10 - 30 µm and an adapted heat treatment program so they are perfectly suited for both the crown and bridge technique and partial dentures.

The successful remanium® star formula

Dentaurum ́s non-precious remanium® alloys have been a synonym for quality in prosthetics for decades and millions are in use. In order to offer all users of new technologies the possibility to keep processing our well-proven and clinically tested alloys, our CoCr alloy remanium® star is available in the same quality for three processing technologies.
