Intended Use

OsteosScaf™ bone grafting material is indicated for filling and/or augmenting intraoral/maxillofacial osseous defects, such as intrabony periodontal osseous defects, furcation defects, augmentation of bony defects of the alveolar ridge, filling of tooth extraction sites, and sinus elevation grafting.

Device Story

OsteoScaf™ is a synthetic, osteoconductive, bioresorbable bone grafting material used in dental and maxillofacial surgery. Composed of a 3-phase composite (PLGA, calcium phosphate, and hydroxyapatite), it is provided as particulates, cylinders, or blocks. The device is implanted by a clinician into osseous defects to serve as a scaffold. Its trabecular structure mimics human cancellous bone, facilitating osteoconduction; as the material undergoes hydrolytic and cell-mediated degradation, it is replaced by native bone tissue. The device provides dimensional integrity during handling and placement. It benefits patients by promoting bone regeneration in surgical sites, such as extraction sockets or sinus elevations, aiding in the restoration of bony architecture.

Clinical Evidence

No human clinical data. Evidence consists of bench testing and animal studies. Bench testing verified chemical composition, impurity levels (ASTM 1185), density, porosity (>80%), particle size, morphology, and mechanical strength. Animal studies (rat calvaria model) demonstrated that OsteoScaf™ is osteoconductive and bioresorbable, showing increased new bone formation compared to coagulum control and faster resorption/bone replacement compared to predicate devices.

Technological Characteristics

3-phase composite scaffold: 22% PLGA, 66% calcium phosphates, 12% hydroxyapatite. Highly interconnected macroporous structure (0.25-1.2 mm pore size, >80% porosity). Form factors: particulate, cylinder, block. Sterilization: irradiation. Complies with ASTM 1185 for impurities.

Indications for Use

Indicated for filling and/or augmenting intraoral/maxillofacial osseous defects in patients requiring bone grafting for periodontal defects, furcation defects, alveolar ridge augmentation, tooth extraction sites, and sinus elevation.

Regulatory Classification

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.

Special Controls

*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.

#### Intended Use:

OsteosScaf™ bone grafting material is indicated for filling and/or augmenting intraoral/maxillofacial osseous defects, such as intrabony periodontal osseous defects, furcation defects, augmentation of bony defects of the alveolar ridge, filling of tooth extraction sites, and sinus elevation grafting.

#### Device Description:

OsteoScaf™ is a synthetic osteoconductive and bioresorbable bone grafting material composed of 3-phase biodegradable polymer and calcium phosphate composite, intended to fill and/or augment intraoral/maxillofacial osseous defects. It functions in the same manner as the predicate devices. The product is available as a particulate, cylinder, or block and is provided in sterile packaging in various dosage volumes.

#### Summary of Technological Characteristics:

The OsteoScaf™ bone grafting material is comprised of a 3-phase composite scaffold comprising poly (lactide-co-glycolide) (PLGA) and 2 osteoclast-resorbable calcium phosphate (CaP) phases that provide the same physical characteristics as the listed predicate devices. The latter are particulates synthesized at physiological temperature and blended with the PLGA phase, and a thin layer of hydroxyapatite surface coating generated in a simulated body fluid at physiological temperature. The Device is configured as a particulate, cvlinder or in a block shape and is packaged in a tray and a chevron type peel pouch for easy use. The product is irradiated to ensure sterility. The Device has a trabecular structure that is the same as the predicate devices and mimics the multidirectional interconnected porosity of human cancellous bone. The Device resorbs and is replaced with natural bone, which remodels during the healing process in the same fashion as that of the predicate devices.

#### Summary of Performance Testing:

Bench and animal studies were conducted to ensure that OsteoScaf™ bone grafting material met the predetermined design specifications. OsteoScaf™ has been tested for a number of chemical and physical characteristics: chemical composition, phase composition, trace of impurities, density and porosity, particle size, morphology, compressive strength and elastic modulus. All these characteristics are equivalent to those of the predicate device. OsteoScaf™ is osteoconductive and bioresorbable based on in vivo studies. When OsteoScaf™ is placed in direct contact with viable bone, new bone forms in apposition to the OsteoScaf™ surfaces and within the interstices of the implant. As the material resorbs, bone tissue grows into the space previously occupied by the implant. The testing performed included the following:

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

| Test Items | Summarized Results |
|----------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Chemical composition | 3-phase composite of 22% (wt) PLGA, 66% Calcium phosphates<br>and 12% hydroxyapatite. |
| Impurity | Testing demonstrates compliance with ASTM 1185 requirements. |
| Pore structure | Highly interconnected macroporous structure of larger than 80%<br>porosity and 0.25~1.2 mm pore size similar to human cancellous<br>bone. |
| Mechanical strength | The devices provides adequate handling properties and strength to<br>ensure dimensional integrity when handled by the surgeon and<br>delivered to bony application sites. |
| Degradation | All three phases of the composite can be resorbed over time through<br>hydrolytic and/or cell-mediated degradation. |
| Animal studies | 1) OsteoScaf™ was used to reconstruct the critical-sized defect in a<br>rat calveria model. The result demonstrated that more new bone<br>formed with OsteoScaf™, compared to coagulum control, after 4<br>weeks.<br>2) OsteoScaf™ gave rise to more new bone formation and faster<br>resorption of the material than the predicate in a rat model.<br>3) The biomechanical testing in rat model demonstrates that<br>OsteoScaf™<br>bone grafting material facilitates replacement with<br>native bone. |

#### Conclusion:

The Company Device (OsteoScaf™) is substantially equivalent to the predicate devices for filling and/or augmenting intraoral/maxillofacial osseous defects, such as intrabony periodontal osseous defects, furcation defects, augmentation of bony defects of the alveolar ridge, filling of tooth extraction sites, and sinus elevation grafting. The Device is also substantially equivalent to the predicate devices in terms of material composition, geometry, and technological characteristics. The material is at least as safe and effective as predicate devices.
