Dyna Helix ST


  • ideally suited for in the mandible type I and II bone
  • no compression zone
  • straight thread and core
  • sharp cutting lower edge to make selfcutting properties ideal
  • all-fit-all abutment system


The design

The Dyna Helix ST implant is a dual cylinder screw designed to give secure mechanical fixation and load distribution in most clinical situations. It is a two-stage, screw type implant that can be used in one-stage surgery if the criteria for one stage surgery are met. It achieves sufficient primary stability and guarantees safe and a-traumatic insertion. The Dyna Helix ST implant is based on root form core with self tapping thread up to the neck of the implant.

Because of the sharp self cutting lower edge of the implant the positioning in height during insertion is easier to manipulate. Pre tapping is necessary when, especially in the cortical bone exists the risk of overheating or creating too much stress in the surrounding area. The lower part of the treads are desgned more horizontally. Becuase of this design the axial forces are transferred more vertically to the alveolar bone.

The absence of the compression zone at the upper part of the implant facilitates surgery for type I or II bone (as defined by Lekholm and Zarb). Based on the new principles to prevent bone resorption the implants are treated with the ART surface.

The biological width principle is respected by means of the V-shape connection to the abutment coined as platform switching. To increase soft tissue connection this part is acid etched. Only a two tenth of a millimetre machined polished collar gives a smooth transition to the abutment. The use of several implant diamters and all-fit abutments gives an ideal combination of simplicity and reliability.
