Craniomaxillofacial Implants: The Universal CMF System is a Craniomaxillofacial (CMF) plate and screw system intended for osteotomy, stabilization and rigid fixation of CMF fractures and reconstruction.
Mandible Implants: The Universal CMF System (mandible modules) is a mandibular plate and screw system intended for stabilization and rigid fixation of mandibular fractures and mandibular reconstruction.
The subject device (combination of Universal CMF System (K022185) and NewGen/Universal Mandibular System (K014263)) consists of multiple modules including fracture and reconstruction modules. The modules consist of straight, angled, hemi/full mandible bridging, curved, and pre-bent plates. The screws in the modules include 1.2-2.7mm self-tapping, self-drilling, and locking screws that vary from 3mm-42mm in length. The plates and screws are made of commercially pure titanium (ASTM F 67-95) and titanium alloy (ASTM F136-98).
It appears there's a misunderstanding of the provided FDA document. The document, K221855 for the "Universal CMF System," is a 510(k) premarket notification for a bone plate and screw system, which is a physical medical device used for fixing craniomaxillofacial fractures.
It is NOT an AI/ML-driven medical device. Therefore, the document does not contain information about:
- Acceptance criteria for an AI/ML algorithm's performance (e.g., sensitivity, specificity, AUC).
- A "study" proving device performance in the context of an AI/ML algorithm (e.g., clinical trials for AI diagnostic accuracy).
- Test set sample sizes, data provenance, expert ground truth establishment, adjudication methods, MRMC studies, standalone algorithm performance, or training set details.
The "performance data" section (VIII) refers to:
- Sterilization validation: Ensuring the device can be properly sterilized by the end-user.
- Performance bench testing: Mechanical tests to ensure the physical plates and screws meet engineering standards (e.g., biocompatibility, insertion/removal torque, failure strength). These are standard tests for physical implants, not AI algorithm performance metrics.
- Animal and Clinical Testing: Explicitly states "not required as a basis for substantial equivalence" for this physical device.
In summary, there is no AI/ML component described in this document, and therefore, it's impossible to extract the requested information about AI/ML acceptance criteria and performance studies from it.
The request asks for specific details relevant to the validation of an AI/ML device. Since this document pertains to a physical implantable device, those details simply do not exist within this filing.

Dear Amelia Kesti:
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. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
{1}------------------------------------------------
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

VIII. PERFORMANCE DATA [§807.92(b)(7)]
There are no modifications to the subject device as part of this submission, only labeling changes. The labeling change included a harmonization of the sterilization parameters, testing for this update is outlined below. Table 4 summarizes the sterilization testing performed on the subject device, Table 5 outlines testing conducted under prior clearances (K022185 and K014263) to demonstrate substantial equivalence.
Sterilization and Biocompatibility Testing
The subject device includes single-use medical implants provided non-sterile to the user. Although there were no modifications to the subject device as part of this submission, the sterilization parameters within the IFU (instructions for use) were harmonized. Compared to the predicate devices, the sterilization testing conducted for the subject device has the same sterilization type, source, and validation standards as the predicate devices. Although there is a change in the sterilization parameters listed in the updated IFU for some components of the subject device, the change does not affect the Sterility Assurance Level (SAL) and there is no change to the way the device is provided (device is still provided non-sterile). The change does not affect performance or biocompatibility of the device. The harmonized sterilization parameters for the subject device do not impact sterility of the final end-product, as the harmonization encompasses the previously valid sterilization parameters that were used for the components under prior clearances (K022185 and K014263). A summary of the sterilization testing for the subject device can be found in Table 4 below.

IX. CONCLUSIONS [§807.92(b)(3)]
In summary, the subject device is substantially equivalent to its predicate device. The subject device's fundamental scientific technology, technological characteristics, and materials of construction are the same as the predicate devices. The subject device's intended use and indications for use have the same scope, content and meaning as the predicate devices. According to the comparison based on the requirements of 21 CFR 807.87 and the information provided herein, it is concluded that the information included in this submission supports substantial equivalence to the predicate device.
