The SmartLock Locking Technology in the VariAx System is designed to encourage a locked screw to plate interface due to the combination of Grade II Titanium plates (softer) and Grade V Titanium screws/pegs (harder).
The threads on the underside of each screw/peg head are designed to engage the circular “lip” in each plate hole upon insertion and create a locked construct. The VariAx system plates processed with Type II Anodization. Type II Anodization is designed to increase the strength of the plates and may reduce the incidence of tissue adhesion. The polyaxial locking capabilities of this system help to provide a 30-degree (±15degrees) locking cone in which each locking screw/peg can be individually placed. A locking screw can be removed, re-directed, and re-inserted in the same hole up to three times, without compromising locking strength.
