The description focuses on the material properties and biological interaction of the device, with no mention of AI or ML.
Yes.
The device is used for the treatment of bony defects caused by periodontal diseases, aiming to restore or improve physiological function.
No.
The device is described as a synthetic material used for the treatment of bony defects, functioning as a bone graft material to bond with tissue. It is a therapeutic device, not a diagnostic one.
No
The device description clearly states that UniGraft is a "synthetic bioactive glass material" manufactured as "irregular shaped synthetic granules," indicating it is a physical material, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for treating infrabony defects caused by periodontal diseases. This is a therapeutic use, not a diagnostic one.
- Device Description: The device is a synthetic bioactive glass material implanted into the body to promote bone bonding. This is an implantable medical device, not a device used to examine specimens from the human body.
- Lack of IVD Characteristics: There is no mention of the device being used to test or analyze samples (like blood, urine, tissue, etc.) outside of the body to provide diagnostic information.
IVD devices are specifically designed to perform tests on specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Device Description
UniGraft is a synthetic bioactive glass material used for the treatment of bony defects caused by periodontal diseases. It is manufactured as irregular shaped synthetic granules, sized at 200-420 microns.
The bioglass used in UniGraft is one of the most extensively studied bioactive glass compositions, and has been shown to bond to bone as well as soft tissue. When implanted in the living tissue, the material undergoes a time dependent surface modification. The surface reaction results in the formation of a calcium phosphate layer, which is equivalent in composition and structure to the hydroxyapatite in bone mineral. This apatite layer provides the bonding interface with bone and certain types of soft tissue.

Summary of Performance Studies
Testing of UniGraft was designed to characterize the finished device and to assure the biocompatibility of the device. The UniGraft device was evaluated comparatively against a predicate device using test methods, including FT-IR, XRD, EDX, bioactivity response and others. The results of these tests demonstrate that the UniGraft device is substantially equivalent to a predicate device.

§ 872.3930 Bone grafting material.
(a)
Identification. Bone grafting material is a material such as hydroxyapatite, tricalcium phosphate, polylactic and polyglycolic acids, or collagen, that is intended to fill, augment, or reconstruct periodontal or bony defects of the oral and maxillofacial region.(b)
Classification. (1) Class II (special controls) for bone grafting materials that do not contain a drug that is a therapeutic biologic. The special control is FDA's “Class II Special Controls Guidance Document: Dental Bone Grafting Material Devices.” (See § 872.1(e) for the availability of this guidance document.)(2) Class III (premarket approval) for bone grafting materials that contain a drug that is a therapeutic biologic. Bone grafting materials that contain a drug that is a therapeutic biologic, such as biological response modifiers, require premarket approval.
(c)
Date premarket approval application (PMA) or notice of product development protocol (PDP) is required. Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.

5. Comparison with Predicate Devices
The UniGraft device is substantially equivalent to devices currently in US commercial distribution, which are classified as endosseous implant for bone filling and augmentation. Examples of such products include PerioGlas. Biogran and OsteoGraf. These products are made of bioactive ceramic materials with similar performance.
6. Device Testing
Testing of UniGraft was designed to characterize the finished device and to assure the biocompatibility of the device. The UniGraft device was evaluated comparatively against a predicate device using test methods, including FT-IR, XRD, EDX, bioactivity response and others. The results of these tests demonstrate that the UniGraft device is substantially equivalent to a predicate device.
