Straumann has developed an improved surface for dental implants called SLA (sandblasted, large grit, acid-etched). The SLA* surface is produced by a coarse sand-blasting process, which leads to macro roughness on the titanium, and outstanding bone fixation is achieved as a result. This process is followed by etching in acid, which produces micropits that can be seen on highly magnified images, which promote cell activity on the surface.
The new SLA (Sand-blasted, Large grit, Acid-etched) surface treatment leads to more intensive bone-implant contact, confirmed by high release moments, which allow earlier functional loading. In healthy patients with good bone quality and quantity, this clinically tested surface provides the possibility of placing the permanent restoration only 6 weeks after the implant surgery.
