Intended Use

These devices are implantable bone plates and bone screws for facial procedures including: 1. Fractures 2. Osteotomies 3. Reconstructive procedures 4. Revision procedures where other treatments or devices have failed

Device Story

Biomet Microfixation Facial Plating System consists of titanium or titanium alloy bone plates, meshes, and screws for internal fixation of facial fractures and reconstruction. Plates available in various geometries (straight, curved, L, T, Z, X, Y, H, etc.) and thicknesses; offered flat or pre-bent. Surgeons contour flat plates intraoperatively using manual instruments. Screws range 1.0mm-2.3mm diameter and 2.0mm-29.0mm length. System used in clinical settings by surgeons to stabilize bone segments. Output is physical stabilization of bone; aids healing by maintaining alignment. Benefits include structural support for facial fractures and reconstructive sites.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing including failure force in bending, rate of deflection, push-through strength, and insertion/fracture torque.

Technological Characteristics

Materials: Titanium or titanium alloy. Form factor: Plates (various shapes/thicknesses), meshes, and screws (1.0-2.3mm diameter). Principle: Mechanical internal fixation. Sterilization: Non-sterile, single-use. Connectivity: None.

Indications for Use

Indicated for patients requiring internal fixation for facial fractures, osteotomies, reconstructive procedures, or revision procedures following failed treatments. Contraindicated in patients with active infection, foreign body sensitivity, limited blood supply, insufficient bone quantity, latent infection, or mental/neurologic conditions preventing adherence to postoperative care.

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.

Device Name:

Biomet Microfixation Facial Plating System

### Intended Use:

These devices are implantable bone plates and bone screws for facial procedures including:

- 1. Fractures
- 2. Osteotomies
- 3. Reconstructive procedures
- 4. Revision procedures where other treatments or devices have failed

#### Contraindications:

- 1. Active infection
- Where material sensitivity is suspected, testing is to be 2. Foreign body sensitivity. completed prior to implantation.
- 3. Patients with limited blood supply, insufficient quantity of bone, or latent infection.
- 4. Patients with mental or neurologic conditions who are unwilling or incapable of following postoperative care instructions.

#### Possible Risks:

- Osteomyelitis, inhibited Osteoporosis, Osteolysis, formation, 1. Poor bone revascularization, or infection can cause loosening, bending, cracking or fracture of the device.
- 2. Nonunion or delayed union, which may lead to breakage of the implant.
- 3. Migration, bending, fracture or loosening of the implant.
- 4. Metal sensitivity or allergic reaction to a foreign body.

{1}------------------------------------------------

- 5. Decrease in bone density due to stress shielding.
- 6. Pain, discomfort, abnormal sensation, or palpability due to the presence of the device.
- 7. Increased fibrous tissue response around the fracture site and/or the implant.
- 8. Necrosis of bone.
- 9. Inadequate healing.

## Description:

The Biomet Microfixation Facial Plating System is comprised of a variety of titanium plates, meshes, and screws with shapes and sizes designed for internal fixation of facial fractures and reconstruction procedures. System implants are manufactured from either titanium or titanium alloy and are intended for single use only.

The Facial Plating System plates that are the subject of this 510(k) submission include variations of straight, angle, curved, L-shape, double T-shape, Z-shape, X-shape, Y-shape, double Y-shape, H-shape, triangle, square, rectangle, matrix, mesh, orbital floor, LeFort, and chin options with various lengths and thickness. Plates are offered flat or pre-bent. Surgeons use cutting and bending instruments intraoperatively to contour flat plates to patient anatomy; prebent plates are contoured by Biomet Microfixation per surgeon specifications or patient anatomy as a convenience. The Facial Plating System screws range in diameters of 1.0mm to 2.3mm and lengths from 2:0mm to 29.0mm.

### Sterility Information:

The plates and screws will be marketed as non-sterile, single-use devices.

## Technological Characteristics:

The subject Facial Plating System devices are similar to the predicate devices in terms of indications, use, and design. The non-clinical testing data shown below demonstrate that the subject devices have equivalent or better mechanical performance when compared to the predicate devices. Minor differences in device geometry do not raise new issues of safety and efficacy.

### Clinical Testing:

Clinical testing was not performed to support this submission.

## Non-Clinical Testing:

Mechanical testing was performed to compare the subject devices to the predicate devices to measure:

- Failure Force (1bf) in Bending of Plates ●
- Rate of Deflection (in/lb) of Plates .
- Push-Through Strength (Ibs) of Plates .
- Insertion Torque (in-oz) of Screws ●
- Fracture Torque (in-oz) of Screws .

{2}------------------------------------------------

The non-clinical test results demonstrate that the mechanical performance of the subject Facial Plating System plates and screws are equivalent or better than the predicate devices and support the substantial equivalence to the predicate devices.

KIZIS89

### Substantial Equivalence:

Biomet Microfixation considers the Facial Plating System modifications equivalent to the Biomet Microfixation's (formerly Walter Lorenz Surgical's) Lorenz 1.0mm, 1.5mm, 2.0mm Plating System cleared under K953385, Paulus Titanium Mini Bone Plates and Bone Screws cleared under K862534. Wuertzburg Plates and Screws cleared under K854886, Lorenz Self-Drilling Screw cleared under K013954, and Lorenz 1.0mm System cleared under K922741.

In conclusion, the subject Biomet Microfixation Facial Plating System devices have the same intended use and similar technological characteristics to the legally marketed predicate devices. Non-clinical testing demonstrates that slight geometrical differences in the devices do not affect safety or effectiveness. The information presented supports substantial equivalence of the subject devices to the predicate devices.
