In their geometry, SCREW-LINE Implants represent conical screw implants. They are available with Promote® (1.4 mm machined implant neck) and Promote® plus surfaces (0.4 mm machined implant neck). The SCREW-LINE Implant is suitable for both late implantations but also for immediate/delayed immediate implantations. The selected healing technique can be either submerged or transgingival. The implant is easily inserted because the taper of the implant body (3°– 9° depending on length and diameter) induces self-centering. The self-tapping thread provides a continuous grip on the bone and high primary stability. The macro-configuration of the implant in conjunction with the Promote® plus surface creates a larger bone contact surface compared with the Promote® surface.
Both the Promote® and Promote® plus versions are provided with the inner configuration (K-Series), which enables the use of platform switching. In the K-Series, the geometry of the three grooves has been changed from round to square and thus also shortened.
The conical implant neck of the SCREW-LINE Implants has been brought higher in the direction of the implant shoulder. This enables extension of the Promote® surface of SCREW-LINE Implants with Promote® and enlargement of the vertical implant-bone contact surface. The cylindrical, machined implant neck area still measures only 1.4 mm with the Promote® surface. Fine adjustment of the apical geometry (rounding) makes the insertion of SCREW-LINE Implants even more bone-conservative.
