2.0 mm fine pitch (non-locking) Screw
Matrix Mandible System
On occasions, it is necessary to pre-drill into bone, but in some instances this can increase hole diameter and impact on screw performance in terms of stripping and pull-out resistance. In order to address this problem, the 2.0 mm Fine Pitch (Non-locking) Screw has been developed (Fig 1). A reduction in pitch of 0.5 mm provides an improvement in screw/bone engagement and pull out retention when compared with the existing 2.0 mm screw with 1.0 mm pitch, and also allows a shorter screw length design of 4 mm. The double lead allows for the same insertion speed as that for standard pitch screws.
