Intended Use

The MatrixWAVE MMF System is indicated for the temporary treatment of mandibular and maxillary fractures and osteotomies in adults and adolescents (age 12 and higher) in whom permanent teeth have erupted.

Device Story

Bone-borne maxillomandibular fixation (MMF) system; consists of wave-shaped commercially pure titanium plates and titanium alloy (Ti-6Al-7Nb) self-drilling locking screws. Used for temporary stabilization of mandibular and maxillary fractures/osteotomies to maintain occlusion during intraoperative fixation and postoperative healing (6-8 weeks). Operated by surgeons in clinical settings. Plates attached to dental arches via screws; dental arches brought into occlusion by wiring around plate hooks or screw heads. Provides mechanical stabilization of bone segments; allows for patient-specific contouring/compression/expansion of plates. Benefits include maintenance of proper occlusion during healing.

Clinical Evidence

No clinical data; substantial equivalence determined via non-clinical performance testing including mechanical construct, screw, corrosion, hook, and biocompatibility testing (ISO 10993-18:2005).

Technological Characteristics

Materials: Commercially pure titanium (plates), Ti-6Al-7Nb titanium alloy (screws), stainless steel (accessory wires). Principle: Bone-borne MMF via locking plate/screw interface. Features: Wave-shaped plates, self-drilling screws, pre-machined threads for off-axis placement, compressible/expandable plate geometry. Provided non-sterile.

Indications for Use

Indicated for temporary treatment of mandibular and maxillary fractures and osteotomies in adults and adolescents (age 12+) with erupted permanent teeth.

Regulatory Classification

Identification

A bone plate is a metal device intended to stabilize fractured bone structures in the oral cavity. The bone segments are attached to the plate with screws to prevent movement of the segments.

Dear Mr. Lees:

This letter corrects our substantially equivalent letter of October 17, 2014.

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

### Predicate Device:

- Stryker Universal SMARTLock Hybrid MMF System (K122313) .
### Indications for Use:

The MatrixWAVE MMF System is indicated for the temporary treatment of mandibular and maxillary fractures and osteotomies in adults and adolescents (age 12 and higher) in whom permanent teeth have erupted.

### Device Description:

MatrixWAVE MMF is a bone-borne maxillomandibular fixation (MMF) system that consists of wave shaped plates (made from commercially pure Titanium) that are attached to the dental arches with self-drilling locking screws (made from Titanium alloy, Ti-6Al-7Nb). The system is intended for temporary stabilization of mandibular and maxillary fractures and osteotomies to maintain proper occlusion during intraoperative bone fixation and postoperative bone healing (approximately 6-8 weeks). The dental arches are brought into occlusion by wiring around the plate hooks and/or accessible screw heads.

### Comparison to Predicate Devices:

#### Indications

The MatrixWAVE MMF System has the same general Indications for Use as the predicate device.

#### 5 510(k) Summary (continued)

Technological Similarities of the MatrixWAVE MMF System to Predicate

- Same general principle of operation: metallic plates and screws each fixated to the . mandible and maxilla, then wired together to achieve maxillomandibular fixation (MMF).
- Same or similar materials used for plates (Titanium), screws (Titanium alloy), and ● accessory wires (stainless steel).
- Compatible with similar diameter wires. ●
- Both use self-drilling screws with the same shaft (i.e. bone purchase) lengths. ●
- . Both have a locking plate/screw interface.
- Both have plates that can be cut & contoured. .
- Both have plates with pre-contoured hooks to support wires or elastics. .
- Both are provided non-sterile. .

Technological Differences of the MatrixWAVE MMF System to Predicate

- Screws in the proposed system have a smaller diameter. .
- Screws in the proposed system have a raised head with a groove to accommodate . wire(s) or elastics for additional (optional) stability.
- . The plate/screw interface of the proposed system has pre-machined threads within the plate and can accommodate off-axis screw placement.
- . The plates of the proposed system have a different shape, hole geometry, and dimensions.
- . The plates of the proposed system can be compressed/expanded to accommodate patient anatomy and/or the location of screw holes.

### Non-Clinical Performance Data:

Non-clinical testing and analyses comparing the proposed devices to the predicate within this submission includes: Mechanical Construct Testing, Screw Testing, Corrosion Testing, Hook Testing, and Biocompatibility Testing according to ISO 10993-18:2005. The non-clinical performance data demonstrate that the mechanical performance of the proposed MatrixWAVE MMF System is comparable to that of the predicate.

### Clinical Performance Data:

Clinical testing was not necessary for the determination of substantial equivalence.

### Substantial Equivalence:

The proposed system has the same general indications as the predicate system. The mechanical testing included in this submission demonstrates that:
