The initial stability of the orthodontic screw is mainly provided
by the cortical bone. With this new product, the initial stability is

effectively improved by increasing the taper Body.
● ∅1.3 Drill - use for the placement of ∅1.4 or ∅1.6 screws
Therefore, sufficient final torque for placement and less possibility ● ∅1.5 Drill - use for the placement of ∅1.8 screw
● Recommended drilling speed: 800rpm (high speed)
of displacement can be achieved when applied with orthodontic force.
● It is recommended to remove some cortical bone by drilling before
placement. If the cortical bone is Resistance very thick, of the the thread drilling against depth external should loadbe

To use orthodontic screws as a stable anchorage, the screw thread
and bone must have sufficient Dresistance against orthodontic forces.
The screw thread and body shape of the new product are designed
to be highly rigid against orthodontic forces.

● Use by coupling with the driver tip. The middle part of the handle is anti-slip
processed for easier placement
The body and thread of the new orthodontic screw are designed to
facilitate stress distribution.
Thus, long-term orthodontic force does not give excessive stress to
the bone with the new orthodontic screw
