Sandblasting before sintering allows us to achieve a much rougher surface than sandblasting after sintering. If you want a rough surface after sintering, you need to exert a lot of pressure, which leads to micro-cracks in the material, weakening the implant system. However, if the surface is roughened before sintering, you need less power during the sintering phase, minimizing the risk of potential micro-cracks. In the subsequent sintering process any micro-cracks will be closed due to the shrinkage. Thanks to this manufacturing method, Patent™ implants have a roughened surface with a 5x larger surface area than a machined surface, without jeopardizing the implant’s strength.
