Thread-Lock (TM)

THREAD-LOCK

Titanium Implant System
for Stable Mandibular
Reconstruction

Featuring:

	Stable locking interface by unique Screw/Plate connection
	The renowned Centre-Drive® Cortex Screws 2.7 mm
	Complete assortment of 3 mm thick Locking Reconstruction Plates
	Easy contouring and adaptation
	Anatomically designed condylar implants
	Implants made of Titanium in Implant Quality

Centre Drive® “Thread-Lock“ Mandibular Reconstruction System (2,7 mm) is indicated to bridge Mandibular Continuity Defects and for the fixation of Bone Grafts.

This System has been specifically designed to fulfill the requirements for an ideal and universal Mandibular Reconstruction System:

	Sufficient mechanical properties for functional load bearing
	Easy 3D-Bending by ergonomically designed bending tools
	Perfect Adaptation
	Biocompatible Material
	A non-problematic attachment of Bone Grafts
	Temporary replacement of the Mandibular Condyles
	Easy to remove

Plate Design Features

	Thickness 3 mm, low profile with rounded edges
	Links - 2.0 mm hole in plate - 2.7 mm screw. The decrease in screw size allows for an increase in material around the screw hole. This design protects the screw hole and threads from derfomation during the plate adaptation procedure.
	Thread in plate
	Under surface of plate relieved between the links for easy bending
	A wide variety of lengths and shapes Recognized as a “positional plate“ - The plate maintains a static position relative to the bone surface as screws are applied. Because the plate is threaded, there is no compression between the plate and bone when the screw is tightened and locked to the plate. This prevents microfractures between screw threads and bone which can occur when a conventional plate is used. (=screw stripping).

Screw Design Features

	diameter 2.7 mm, pitch 1.25 mm
	self cutting
	length 8 mm - 22 mm
	uniquely designed bullet tip - as the screw is advan- ced through the plate, the screw self threads into the bone preventing displacement of the plate off the bone. Lifting of the plate cannot occur.
	no emergency screw - no need for an emergency screw. It is impossible to strip a screw in bone because of the locking mechanism. The screw locks to the plate which avoids creating compressive forces, thus protecting the screw thread and bone interface.

Screw Insert Features

decrease the amount of dead space to prevent potential infection.

important factor when secondary reconstruction with bone grafting is considered. The inserts will protect the thread lock mechanism.

bone grafts may be stabilized using the locking
2.7 mm screws or lagged into position using 2.3 mm screws.
