Q-Lock connection

The implant-abutment Q-Lock connection is a unique combination of four stabilizing components:

  • Deep cone ensures stability and tight seal of the connection
  • Solid hexagon as an anti-rotation element
  • Reinforcing cylinder – tube in tube
  • Cone under the screw head

The stress of implant and the abutment is examined through the use of strength test with kinematics of chewing. The test consists of 5 million cycles, where strength of the connection implant-abutment-screw is checked. This amount of cycles corresponds to about 20 years of the implant lifetime.
