NTA Spure Implant — Surface Treatment “SLA”

The SLA surface is produced by a large grit sand-blasting process with corundum particles that leads to a macro roughness on the titanium surface. This is followed by a strong acid-etching bath with HCl at elevated temperature for several minutes, resulting in fine 2–4 μm micro pits superimposed on the rough-blasted surface. Since the surface is not micro-porous, it provides no enclosed volumes and therefore reduces vulnerability to bacterial contamination.

X-ray photoelectron spectroscopy has identified the chemical composition of the SLA surface as titanium dioxide (TiO2). This analytic method examines the first atomic layers of the material, ensuring biocompatibility at the exact points where tissue fluids and cells come into direct contact.

Platform Switching

Implant–abutment junction is positioned closer to the center of the implant and away from the implant–bone interface. In combination with the conical connection, crestal bone loss is rarely observed in NTA Spure implants.

Conical Connection

The conical connection provides bacterial sealing, preventing micro-movement and micro-leakage. This supports crestal bone preservation and prevents loosening of the abutment screw. The inner hex index ensures precise abutment seating.

Cutting Edge

Triple-sharp drill architecture allows fast and comfortable osteotomy preparation with reduced heat generation, shorter drilling time and minimal postoperative discomfort.
