Biotec Implant

SLA - Sandblasted and acid etched surface :
Biotec Dental Systemâ„¢ have a ( Bio-S active) bio active surface tec.
Commercially available dental implants are usually both blasted by particles and then subsequent etched by acids.
This is performed to obtain a dual surface roughness as well as removal of embedded blasting particles.
The etching reduces the highest peaks while smaller pits will be created and the average surface roughness will be reduced.
Typical Sa values for blasted and acid etched implants are 1-2 pm.
The chemical process of the acid etching will change the surface structure and it has been reported a creation of a titanium hydride layer with a thickness of 1-2 pm intermediate the surface oxide and the bulk metal.
Further, by rinsing the SLA implant in a nitrogen atmosphere and storing in saline solution until installation, the amount of carbon contamination could be reduced and improving the hydrophilicity of the implant surface.
The result of this procedure is creating a new hydrophilic surface (SLActive).
This procedure allows the SLActive to maintain a chemically active surface that conditioned to the human body.
