 Common screw |
They resist directly to pull-out forces
which develop between bone and implant.
|
 SURFIX® screw |
 |
||
 |
The common screw undergoes an action leverage, because of persistent mobility between its head and the implant. |
 |
|
Because of the screw-to-plate locking
mechanism, the SURFIX® screw is not subject to action leverages.

 |
The common screw indirectly resists to
shear forces between bone and implant.
|
 |
|
Because of its secure screw-to-plate
locking mechanism, the SURFIX® screw resists directly to shear forces.
|

 |
The common screw cannot resist to 'ploughing' forces
between bone and implant.
