Sandblasted, large grit, acid-etched implant surface (SLA)

Sandblasted, large grit, acid-etched implant surface, (SLA) is a type of surface treatment that creates surface roughness with the goal of enhancing osseointegration through greater bone-to-implant contact (BIC). The SLA process increases the rate at which osseointegration occurs by using a combination of grit and acid etching to give the surface increased roughness on multiple levels. This allows osteoblasts to proliferate and adhere to the implant surface. Through osseointegration, SLA can help provide increased stability of the implant which will ultimately lengthen its longevity. The use of specialized implants by Straumann SLA implants, such as the SLActive implant and the Roxolid SLA implant, reduces the amount of treatment time required while also increasing the treatment predictability. The Roxolid SLA implant can also reduce the need for bone augmentation to assist those patients who have insufficient bone. The SLA process offers a variety of benefits to patients requiring increased ossification prior to an implant.
