The SCREW-LINE and ROOT-LINE implants are available with the abrasive-blasted, acid-etched Promote® surface. The microstructured, rough surface for SCREW-LINE implants with Promote® surface extends in the endosseous area apically up to 1.4 mm below the implant shoulder and for ROOT-LINE implants with Promote® surface up to 2.0 mm below the implant shoulder. For SCREW-LINE implants with Promote® plus surface, the rough/smooth boundary is up to 0.4 mm below the implant shoulder. Promote® has proven itself as the surface for anchoring CAMLOG® implants in the bone. Scientific studies show that implants with Promote® surface rapidly and efficiently integrate into the bone.
