Master-Pin-Control The Master-Pin-Control Bone Management® system is used for the fixation of membranes (absorbable, non-absorbable and titanium membranes) in order to avoid micro-mobility of the graft. Thanks to the sharp tips and the stable construction, the pins can be precisely inserted into cortical bones. The pins have an additional minithread and are a hybrid composed of a screw and pin. The thread makes easy and safe removal possible after a healing period has taken place. This thread enlarges the surface of the shaft at the same time and therefore clearly offers more stability.
