The SOP TPO is a new generation plate utilising the locking function of the SOP system enabling the use of screws. The SOP screw holes are slightly diverging. The plate will require the use of the 2.5/3.5mm SOP double drill guide. For further information on the SOP system please refer to the SOP user guide. In order to guarantee the best fit between the SOP TPO plate and the screws we recommend the exclusive use of Orthomed screws.
