Surface treatment promotes osseointegration

Surface finish is a very important topic in metal cutting. Surface treatment is a unique topic for bone screws and Swiss machining.

While some bone screws are temporary and therefore eventually removed, most are in place. It turns out that the surface finish of the screw has a lot to do with promoting bone growth, so the screw is firmly embedded and bone grows around it.

While scientists continue to work on developing special coatings that can be used to promote bone integration (read one example), screw makers are finding that rougher finishes and other different types of surfaces can help promote bone growth.

The invention of direct laser sintering (also known as 3D metal printing) allows previously unattainable levels of porosity, not just rough surface finish, and promotes bone integration. That's why 3D manufacturing is likely to be the future for bone screws and many other medical device applications.

However, most materials used to make orthopedic bone screws and dental anchors are not heat-treated. Instead, they get their strength from cold work, something 3D metal printing can't do.

This means that before laser sintering, you still have to start by machining rods or wires!
