Innovation in implant surface treatments is one of the fundamental advantages of the Straumann Dental Implant System.
Roughened surfaces show advantages over smooth surfaces:
• Better osseointegration
• Enhanced bone-to-implant contact
• Better biomechanical and functional stability
At 20–40μm, the macrostructure of the SLA and SLActive surfaces leads to optimal cell adherence and proliferation in the cavities of the roughened implant surface. Micro-rough surfaces enhance the proliferation of cells, morphology, the rate of cell spreading, the formation of a 3-dimensional cell matrix, and significantly increase the number of cells attached to the surface1.
The technique used to create the SLA and SLActive surface – sand-blasted, large grit, acid-etched – is now the industry standard and has been copied by many implant companies. Still, no other company can claim the same success that has been achieved through Straumann’s technology.2
The SLA implant reduces healing time to 6 weeks when compared to titanium plasma spray and boasts a 98.8% success rate.
