### Dear Dr. Bounaud:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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 IDENTIFICATION
The 3D Accuscan Facial Contour Implant is substantially equivalent to the following predicate:

The predicate device has not been subject to a design related recall.
### DEVICE DESCRIPTION
The Customized Contour Implant is a patient-matched for augmentation, reconstructive and cosmetic surgery of the facial regions, specifically the nasal contour, the malar cheek contour, and the chin contour. The device is a single use implant intended for long term implantation as a space occupying device to form a contoured feature. The customized
{4}------------------------------------------------
implant is made of medical grade silicone elastomer, in a range of durometers as specified by the surgeon.
The patient's own medical imaging (e.g., Computerized Tomography (CT) scan) is translated into a digital model of the patient's skull using VSP® Software from 3D Systems. At the recommendation of the surgeon, the VSP® Software is used either to 3D-print a skull model for the surgeon to fashion a solid implant model with commercially available plaster or silicon kits, or to create a digital implant model as an STL file. Implantech Associates manufactures the customized molds from the solid implant model provided by the surgeon, or the digital implant model provided by 3D Systems, using plaster molds or 3D-printed molds as appropriate. The Customized Contour Implant is manufactured from the customized molds and provided to the surgeon, sterile or non-sterile.
Image /page/4/Figure/3 description: The image shows a diagram of the process for creating customized implants. The process starts with the surgeon's specifications, which are then used to create a solid model or digital file. This file is then used to create a mold, which can be a plaster mold or a 3D printed mold. Finally, the mold is used to create a customized implant, which can be sterile or non-sterile.
# INDICATIONS FOR USE
The Customized Contour Implant is intended for augmentation, reconstructive and cosmetic surgery of the facial regions. The Customized Contour Implant is pre-shaped to the surgeon's specification to meet the needs of a particular patient.
# COMPARISON OF TECHNOLOGICAL CHARACTERISTICS
The subject device has the same intended use, target population, design, and materials as the device cleared in K913761.
Unlike the predicate device cleared in K913761, manufacturing of the Customized Contour Implant includes two additional routes involving the use of 3D printing technology to create patient-specific molds and implant models derived from CT scans of a patient. VSP® Software by 3D Systems provides the transfer of the patient's medical imaging to a digital format appropriate for 3D printing of patient-specific molds and implant models.

Image /page/5/Picture/1 description: The image shows the logo for "Implantech Superior Patient Aesthetics". The word "Implantech" is in a bold, italicized font, with the "I" being much larger than the other letters. Below "Implantech" is the phrase "Superior Patient Aesthetics" in a smaller, less bold font. The logo is in white against a black background.
# SUMMARY OF NON-CLINICAL TESTING
No FDA performance standards have been established for the Customized Contour Implant. The following non-clinical tests were performed in order to demonstrate safety based on current industry standards:
- . Sterilization validation per ISO 17655-1 and ANSI/AAMI/ISO 20857
- Packaging validation per ISO 11607
- Shelf life validation with accelerated and real time aging studies
- Cytotoxicity testing per ISO 10993-5
- Bacterial endotoxins testing per ANSI/AAMI ST72
- 3D printer validation: Fortus 360MC 3D Printer and its ancillary equipment were validated to accurately print a 3D image of a predetermined shape (1 inch cube, 1 inch diameter sphere) using STL file inputs. STL file creation using the VSP® software was validated prior to the 3D printer validation.
The results of these tests indicate that the Customized Contour Implant is substantially equivalent to the predicate device.
# CONCLUSION
Based on the testing performed, including bioburden testing, cytotoxicity testing, and physicochemical testing, it can be concluded that the subject device does not raise different questions of safety or effectiveness when compared to the predicate device. The similar indications for use and technological characteristics for the proposed Customized Contour Implant are assessed to be substantially equivalent to the predicate device.
