SLA®

Well-documented rough surface.

Our SLA® surface was commercially launched in 1998 and is one of the most documented rough surfaces in implantology. The SLA® surface is produced using a large-grit sandblasting technique that generates a macro-roughness on the titanium surface. This is followed by acid-etching that superposes a micro-roughness. The resulting topography offers an ideal structure for cell attachment.

Longevity and efficiency in daily practice

The longevity of Straumann® Soft Tissue Level implants with the SLA® surface has been demonstrated in a long-term study. During the 2010 ITI World Symposium, the following outstanding 10-year results on the SLA® surface were presented1:

  • Unchanged survival rate: in the examined 23 patients, no implants were lost between years 5 and 10
  • No statistically significant bone loss occurred between 5 and 10 years
  • Prosthesis survival of 96 %
  • No signs of peri-implantitis were noted at 10 years
  • Patient satisfaction was high

Marginal bone loss in the test and control group after 5 and 10 years
