Titanium

Suprastructures are milled from standard Grade 2 titanium.

Grade 2 titanium is "Commercially Pure Titanium" and is approximately 99.6% pure. Grade 2 titanium is less rigid than Grade 5 titanium. The strength lies at a clinically relevant level: the usual tensile strain is 275 MPa, the highest possible tensile strain is 345 MPa. Grade 2 titanium is usually used for corrosion resistant applications where a relatively low weight plays a significant role.

Grade 5 is the most common Titanium alloy. It consists of 90% Ti, 6% Aluminium and 4% Vanadium. Grade 5 titanium is stronger than Grade 2, with a usual tensile strain of 830 MPa and the highest possible tensile strain of 890 MPa.  If the suprastructure requires extra strength, then request it milled in Grade 5 Titanium.

Chrome Cobalt

The CoCr alloy, from which the Bridges are milled, is a very corrosion-resistant NEM alloy on a CoCrW basis. It has excellent mechanical traits and is suitable for use as baking-alloy.

It can be coated with all ceramic dental materials that cover the CTE range of 14.6 µ m/m.K (25-500°C) and of 14.9 µ m/m.K (25-600°C).

The composition consists of Co (54.0%), Cr (20.1%), W (16.45%), Nb (0.2%), Fe (7.45%), Si (1.5%) and Mn (0.3%).

Baking the ceramic occurs according to the user's manual for the ceramic material used for covering.
