Intended Use

MASTERGRAFT® Resorbable Ceramic Granules may be used alone or in combination with autograft to provide a bone void filler that is resorbed/remodeled and is replaced by host bone during the healing process. MASTERGRAFT® Resorbable Ceramic Granules is packed into bony voids or gaps to fill and/or augment dental oral/maxillofacial bony tissue. These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. Procedures include;

  • Filling of periodontal defects
  • Filling of dental extraction sockets
  • Filling of cystic defects
  • Sinus lifts
  • Alveolar ridge augmentation
  • Oral/maxillofacial augmentation or reconstruction. .
    MASTERGRAFT® Resorbable Ceramic Granules may be used with or without internal fixation, and may be mixed with autograft as a bone graft extender.
Device Description

MASTERGRAFT® Resorbable Ceramic Granules is made of medical grade combination of hydroxyapatite and b-tricalcium phosphate. MASTERGRAFT® is provided in a 60 percent hydroxyapatite and 40 percent b-tricalcium phosphate formulation. Alternatively, MASTERGRAFT® may be provided in a 15 percent hydroxyapatite and 85 percent b-tricalcium phosphate formulation. The product is supplied sterile for single patient use. MASTERGRAFT® Resorbable Ceramic Granules is an osteoconductive porous implant.

AI/ML Overview

This 510(k) premarket notification for Medtronic Sofamor Danek MASTERGRAFT® Resorbable Ceramic Granules primarily focuses on expanding the indications for use to the oral and maxillofacial region, based on substantial equivalence to previously cleared devices. Therefore, the traditional "acceptance criteria" and detailed "study that proves the device meets the acceptance criteria" in terms of performance metrics like sensitivity, specificity, accuracy, and confidence intervals, which are common in AI/Diagnostic device submissions, are not applicable here.

Instead, the "acceptance criteria" for this type of submission revolve around demonstrating substantial equivalence to predicate devices for the new indications. The "study" proving this involves a comparison of the device's characteristics (material composition, intended use, technological characteristics) to the predicate devices.

Here's a breakdown of the requested information based on the provided document:


1. Table of Acceptance Criteria and Reported Device Performance

As noted above, for this 510(k) application, the acceptance criteria are not performance metrics but rather a demonstration of substantial equivalence.

Acceptance Criteria (for Substantial Equivalence)Reported Device Performance (Demonstration)
Material Composition Equivalence: Device material is equivalent to predicate devices.MASTERGRAFT® Resorbable Ceramic Granules is made of a medical-grade combination of hydroxyapatite and b-tricalcium phosphate (60% HA, 40% b-TCP or 15% HA, 85% b-TCP). This composition falls within the established parameters of the predicate devices.
Intended Use Equivalence (for expanded indications): Device's intended use for oral and maxillofacial applications is equivalent to predicate devices.The device is intended for use alone or combined with autograft as a bone void filler for bony voids or gaps that are not intrinsic to the stability of the bony structure in the oral and maxillofacial region (e.g., periodontal defects, extraction sockets, cystic defects, sinus lifts, alveolar ridge augmentation, oral/maxillofacial augmentation or reconstruction). This expanded indication is argued to be substantially equivalent to the existing indications of the predicate devices.
Technological Characteristics Equivalence: Device shares similar technological characteristics with predicate devices.The document states "Documentation is provided that demonstrates MASTERGRAFT® Resorbable Ceramic Granules to be substantially equivalent to the previously cleared MASTERGRAFT® Resorbable Ceramic Granules (K020986, SE 07/22/2002) and MBCP™ (K051885, SE 09/16/2005)." This implies that the design, manufacturing, and operational principles are similar.
Performance Data (if applicable for substantial equivalence): Any relevant performance data (e.g., biocompatibility) supports equivalence.While not explicitly detailed as performance studies in this summary, the substantial equivalence claim inherently relies on the understanding that the device performs similarly to the predicates in terms of osteoconductivity and resorption characteristics, given the similar composition. The 510(k) process typically assumes that if a new device has similar technological characteristics and intended uses to a predicate, it will function similarly.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The provided document does not describe a "test set" in the context of clinical performance or algorithm evaluation. This submission is for substantial equivalence based on material composition and intended use expansion, not for demonstrating clinical efficacy through a new trial with a distinct test set.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Not applicable. There was no clinical "test set" requiring expert ground truth establishment for this 510(k) submission.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. There was no clinical "test set" requiring adjudication for this 510(k) submission.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This is not an AI/diagnostic device, and no MRMC study was conducted or referenced in this summary.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This is a medical device (bone graft material), not an algorithm or AI system.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

Not applicable in the conventional sense of a clinical study for a diagnostic or AI device. The "ground truth" for this submission is embedded in the regulatory precedent set by the predicate devices (K020986 and K051885) and their established safety and effectiveness. The "truth" being established is that the new device is substantially equivalent to these already-approved devices.

8. The sample size for the training set

Not applicable. There was no "training set" as this is not an AI/machine learning device.

9. How the ground truth for the training set was established

Not applicable. There was no "training set."


Summary of the Study for Substantial Equivalence:

The "study" for this 510(k) submission is a comparison to predicate devices (MASTERGRAFT® Resorbable Ceramic Granules K020986 and MBCP™ K051885). The manufacturer provided documentation demonstrating that the subject device shares the same material composition (hydroxyapatite and b-tricalcium phosphate) and similar technological characteristics, and that its expanded oral and maxillofacial indications are substantially equivalent to the existing indications of the predicate devices. The FDA reviewed this documentation and concurred with the substantial equivalence claim, allowing the device to be marketed for the specified expanded indications. This process does not involve new clinical trials or performance studies to establish "acceptance criteria" through statistical metrics.

Dear Mr. Massey:

This letter corrects our substantially equivalent letter of January 9, 2009.

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 (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.

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.
