Bego Wirobond C Metal

Wirobond C a metal-ceramic alloy, free of nickel and beryllium, is an example of the exceptional expertise that makes us specialists in the metal-ceramic sector. Wirobond C has been processed successfully worldwide for over 25 years and as a Type 4 alloy fulfils all the criteria of the ISO 22674 and ISO 9693-1 Standard. 

Advantages:

• Reliable recognition of the casting point both with centrifugal casting machines and vacuum-pressure casting machines, e.g. Nautilus or Fornax – due to its special composition
• Easy casting and reliable further processing
• A wide range of dental restorations are covered with only one alloy, e.g. veneered crowns or removable partial dentures
• Due to the high strength of the alloy you are always on the safe side, even with problematic situations such as long-span bridges

Wirobond C can be veneered using composite or porcelain. All conventional veneering porcelains with corresponding CTE values can be used.

Advantages:

• The element cerium contained in the alloy ensures a high bond strength with the porcelain
• No expensive bonder is required for producing a reliable metal-ceramic bond
• The durable, reliable bond minimises the risk of splitting off intraorally at a later date
• High degree of aesthetics with the porcelain of your choice

Wirobond C is ideal for laser-welding due to the optimal, carbon-free composition. Solder and welding joints can be polished very easily and are no longer visible after polishing.

Advantages:

• When welded correctly, a strength value can be attained that reaches the inherent strength of Wirobond C
• A reliable, durable and biocompatible joint is possible by soldering and laser-welding

The optimised chrome, molybdenum and tungsten content guarantees the excellent corrosion behaviour of Wirobond C. These high purity elements produce a dense, adhering passive layer after casting that reliably protects against corrosion.

Advantages:

• No cytotoxic potential, no skin irritations or allergic sensitisation
• Guarantee of biocompatibility
• Safety for the dentist and patient
