The aim of surgical fracture treatment is to reconstruct the bony anatomy and restore its function. According to the AO, internal fi xation is distinguished by precise reduction, stable fi xation, preservation of blood supply, and early, functional mobilization1, 2. Plate and screw osteosynthesis has been established and clinically recognized for some time.

Keeping the AO philosophy at its core, Matrix is the plating platform for internal fi xation of the craniomaxillofacial skele-ton – addressing neuro, craniofacial, mandibular and orthog-nathic surgery. Matrix is a streamlined, comprehensive sys-tem that offers fl exibility, ease of use and high quality implants and instruments.

Simple– All screws work with all plates within each Matrix system– One blade for all screws within each Matrix system– Color coding by strength for easy identifi cation

Effective– Low plate-screw profi le– Self-retaining screws/blades– Rounded plate edges

Effi cient– Standardized instrumentation– Reduces inventory for hospitals, without compromising

clinical solutions

Plate and Screw Color CodingThe color coding of implants (plates and screws) in the MatrixORTHOGNATHIC LOCK system helps to identify the level of strength. The color-coding scale for plates and screws is described below.

PlatesGold = 0.8 and 1.0 mm thick plates (maxillary and mandible)

Screws: Locking/Non-locking

Bronze = 1.5 mm self-tapping screws; LOCK and non-locking

Silver = 1.5 mm self-drilling screws; LOCK and non-locking

Blue = 1.85 mm self-tapping screws; LOCK and non-locking

Purple = 1.85 mm self-drilling screws; LOCK and non-locking

Pink = 2.1 mm self-tapping screws (emergency for 1.85 mm screws); non-locking only

In the MatrixORTHOGNATHIC LOCK system the plate hole dimensions allow all the screws to be used with all the plates. This makes it a simple and intuitive system in which the screw strength (see color code) can be chosen based on the application (Le Fort I, Sagittal Split Osteotomy or Genio-plasty).

In 1958, the AO formulated four basic principles, which have become the guidelines for internal fixation1, 2. They are:

Anatomic reductionFracture reduction and fixation to restore anatomical rela-tionships. A comprehensive implant and instrument selection offers the ability to address most simple and complex fixation needs.

Stable fixationStability by rigid fixation or splintage, as the personality of the fracture and the injury requires. The MatrixORTHOGNA-THIC LOCK plates and screws are optimized to achieve stable bone fixation.

Preservation of blood supplyPreservation of the blood supply to soft tissue and bone by careful handling and gentle reduction techniques. Instrumen-tation and new gentle implant profiles and edges minimize disruption of soft tissue and preserve vascular blood flow bone healing.

Early, active mobilizationEarly and safe mobilization of the part and patient. The MatrixORTHOGNATHIC LOCK system implants, combined with AO technique, provide stable fixation enough to allow a functional aftercare.

03.503.039 Plate Cutter for MatrixMIDFACE

Cut and contour the plate according to the bending tem-plate and bony anatomy using the plate cutter and the bending pliers, respectively. Bend the plate between the holes as necessary. Ensure that the plate is adapted to the bony anatomy.

When using locking screws, an exact match is not required. With locked screws, plate stability does not depend on the plate-to-bone contact.

Notes:– Etched lines, in 1 mm increments, to facilitate plate

bending.– When using non-locking screws take care to match the

anatomy.– Lateral portion of Matrix LOCK Maxillary Plates includes a

thinner bar section for adjustment according to the angle of the Le Fort I osteotomy.

Precaution: Confirm that plate positioning, drill bit and screw length allow for adequate clearance of nerves, tooth buds and/or tooth roots, and the edge of the bone.

Warnings: – Do not alter the bend of the prebent plates by more than

1 mm in either direction.– Do not excessively bend the plates as it may produce in-

ternal stresses which may become the focal point for eventual breakage of the implant.



4Optional: Confirm plate position on the bone using the positioning hole

If pilot hole is desired, select the appropriate 1.4 mm drill bit length to allow for the adequate clearance of nerves, tooth buds and/or tooth roots.

Insert the proper length Matrix screws (non-locking) into the positioning hole. Place the plate in the desired position . Insert the screw until seated. Do not fully tighten.

Drill a second hole on the opposite side of the osteotomy and use a locking or non-locking screw to fixate the plate to the bone . Tighten the screw until seated. Do not fully tighten.

Place a second plate symmetrically on the other side of the maxilla, repeating the steps described above , .

If necessary this procedure can be repeated and the plate repositioned.

Maxilla can be positioned as desired and held in place by tightening screws. Continue to step 5.

Notes:– The surgeon can determine whether a left or right plate

will be implanted first.– Self-drilling and self-tapping screws are available.

Precautions:– Confirm that plate positioning, drill bit and screw length

allow for adequate clearance of nerves, tooth buds and/or tooth roots, and the edge of the bone.

– Drilling speed should never exceed 1800 RPM. Higher rates can result in thermal generated necrosis of the bone and an increased hole diameter. The detriments of an oversized hole include reduced pullout force, increased ease of screws stripping in bone, and/or suboptimal fixa-tion. Always irrigate during drilling.

– Use the appropriate amount of screws to achieve stable fixation. Stable fixation requires a minimum of two screws per segment.


5Fixate plate to the boneIf pilot hole is desired, select the appropriate 1.4 mm drill bit length to allow for the adequate clearance of nerves, tooth buds and/or tooth roots.

Insert the remaining Matrix screws of appropriate length to fixate the plate to the underlying bone. Alternate between osteotomy sides , , , and maxilla sides , , , .

Note: Self-tapping and self-drilling screws are available.

Precautions: – Confirm that plate positioning, drill bit and screw length

plate should be contoured as far proximally as possible.


Warning: Do not excessively bend the plates as it may produce internal stresses which may become the focal point for eventual breakage of the implant.


Mandible / Sagittal Split / SplitFix Plate Fixation

4Primary plate fixation


Fixate the SplitFix plate to the bone by drilling and inserting the proper length 1.85 mm Matrix screws in the specified sequence as shown ,,. Screws should be placed mono-cortically.




– Drilling speed should never exceed 1800 RPM. Higher rates can result in thermal generated necrosis of the bone, and an increased hole diameter. The detriments of an oversized hole include reduced pullout force, increased ease of screws stripping in bone, and/or suboptimal fixation. Always irrigate during drilling.

– The 1.5 mm MatrixMIDFACE screw is not recommended for sagittal split fixation.



5Intraoperative correction of occlusion

Release the intermaxillary fixation and inspect the occlusion.If the occlusion needs to be adjusted, loosen screw 3 in the slider plate as shown.

The distal bone segment can now be shifted horizontally and vertically until the occlusion has been corrected.

Retighten screw 3 in the slider. The process can be repeated as many times as necessary.

Note: Ensure that the desired condylar position has been achieved.

6Final plate fixation

Using a 1.4 mm drill bit to pre-drill, insert the remaining 1.85 mm Matrix screws of the appropriate length in holes 4 to 7.

Remove screw 3 and the slider plate component. Repeat this step on contralateral side. Ensure fixation of the mandible is adequate to withstand the sagittal forces.

Precautions:– Drilling speed should never exceed 1800 RPM. Higher

rates can result in thermal generated necrosis of the bone and an increased hole diameter. The detriments of an oversized hole include reduced pullout force, increased ease of screws stripping in bone, and/or suboptimal fixa-tion. Always irrigate during drilling.

– Use the appropriate amount of screws to achieve stable fixation. Stable fixation requires two screws per segment.

Warnings:– The slider is used strictly for intraoperative use only; do

not leave it in situ.– Previous changes in the temporomandibular joint may

affect surgical outcome.


Mandible/Genioplasty Plate Fixation


After the osteotomy has been performed and the position/advancement of the genioglossus segment has been estab-lished, select the plate size that best suits the bony anatomy, treatment objective and the quantity and quality of bone.
