Intended Use

NovaBonc-BBG - Resorbable Bone Graft Substitute is indicated to be packed into bony voids or gaps to fill and/or augment dental intraosseous, oral and cranio-/ maxillo-facial defects. These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone, including: periodontal/infrabony defects; alveolar ridge augmentation (sinusotomy, osteotomy, cystectomy); dental extraction sites (ridge maintenance, implant preparation/placement); sinus lifts; cystic defects; craniofacial augmentation. The device provides a bone void filler that resorbs and is replaced with bone during the healing process. NovaBone-BBG may be used alone in a manner comparable to autogenous hone graft chips or allograft bone particulate (demineralized freeze dried bone), or it may be mixed with either allograft or autograft bone or bone marrow as a bone graft extender. NovaBone-BBG is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure.

Device Story

NovaBone-BBG is a synthetic, resorbable, osteoconductive bone graft substitute used as a non-structural scaffold for bone regeneration. It consists of two calcium-phosphorus-silicate bioactive glass components: a melt-derived Bioglass and a solution-gelation (sol-gel) derived glass. The sol-gel component is more soluble, allowing for more rapid initial absorption and tissue infiltration compared to standard melt-derived glass. The device is supplied as a particulate to be packed into defect sites by a clinician familiar with bone grafting techniques. It is used in dental, oral, and cranio-/maxillofacial procedures, either alone or as an extender mixed with autograft/allograft bone or bone marrow. The material is designed to be resorbed and replaced by host bone during the healing process. It provides no mechanical support for load-bearing defects; rigid stabilization must be achieved via standard internal or external fixation techniques.

Clinical Evidence

Evidence includes comparative in vivo performance data between NovaBone-BBG (and its individual sol-gel component) and the predicate PerioGlas, supplemented by in vitro testing. No human clinical trial data is described.

Technological Characteristics

Particulate, synthetic, inorganic, osteoconductive bone void filler. Composed of two calcium-phosphorus-silicate bioactive glass materials: one melt-derived and one sol-gel derived. Non-structural scaffold; requires external/internal fixation for load-bearing sites. Biocompatible; resorbable.

Indications for Use

Indicated for patients requiring filling or augmentation of dental intraosseous, oral, and cranio-/maxillofacial bony voids or gaps resulting from surgery or trauma. Specific applications include periodontal/infrabony defects, alveolar ridge augmentation, extraction sites, sinus lifts, and cystic defects. Contraindicated for use in bony voids intrinsic to the stability of the bony structure.

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.

#### 4. Device Description

NovaBone-BBG is a synthetic resorbable ostcoconductive bone graft substitute composed of two similar calcium phospho-silicate bioactive glass materials. The device is intended for dental intraosseous, oral, and cranio-/maxillofacial bony defects. The major component is a melt-derived calcium-phosphorus-sodiumsilicate (Bioglass) designed specifically for its absorbability and ostcoconductive nature. The second component is a calcium-phosphorus-silicate bioactive glass, chemically similar to the major component, but derived via a solution-gelation (sol-gel) process. The secondary sol-gel component is more rapidly absorbed from the graft site than the standard melt-derived component, opening additional space between the Bioglass particles for more rapid tissue infiltration and replacement by host bone during the healing process.

These derects injury to the bone, including: periodontal/infrabony defects; alveolar ridge augmentation (sinusotomy, osteotomal/infraoony - cercets) extraction sites (ridge maintenance, implant osteotonly, "Cystcetonly), "centur" cystic defects; craniofacial augmentation.

NovaBone-BBG is indicated only for bony voids marrow that are not intrinsic to the stability of the bony structure.

## Technological Characteristics 6.

The technological characteristics of NovaBone-BBG, PerioGlas, and Biogran are similar, although not identical. All are designed to be osteoconductive spacefilling particulates to be gently packed into defect sites and to be used as a nonstructural scaffold for the body's natural healing and bone regeneration process. Structuring bearing the three devices are similar in nature, all being particulate, ro thetic, inorganic, biocompatible and ostcoconductive materials.

The main technological difference between NovaBone-BBG and the two predicate The mani tooming.com the predicates are single-material Bioglass devices, the devices is and contains Bioglass and a second sol-gel derived bioactive glass NovaDone DDG contares Dass is composed of calcium, phosphorus, and silicon, similar to the Bioglass component, but without the sodium. For all three devices, similar to the Diograss antially absorbed within the six-month timeframe normally associated with bone remodeling, the devices being replaced by new bone tissue. The sol-gel phase of the NovaBone-BBG is more soluble than the standard melt-I ne sof get phase of the itting a more rapid initial absorption and therefore derred Broghass, pormising at an earlier period than for the predicates.

In vivo performance data comparing NovaBone-BBG and/or the individual sol-gel component to PerioGlas are summarized.

## Warnings and Precautions 7.

NovaBone-BBG does not possess sufficient mechanical strength to support load bearing defects prior to soft and hard tissue ingrowth. In cases where load support is required, standard internal or external stabilization techniques must be followed to obtain rigid stabilization in all planes.

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

NovaBone-BBG is intended for use by clinician familiar with bone grafting and internal/external fixation techniques. NovaBone-BBG must not be used to gain screw purchase or to stabilize screw placement.

- 8. Complications
Possible complications are the same as to be expected of autogenous bone grafting procedures. These may include: superficial wound infection, deep wound infection, deep wound infection with osteomyelitis, dclayed union, loss of reduction, failure of fusion, loss of bone graft, graft protrusion and / or dislodgement, and general complications that may arise from anesthesia and / or surgery. Complications specific to oral/dental use are those as may be typically observed for similar bone grafting procedures and may include: tooth sensitivity, gingival recession, flap sloughing, resorption or ankylosis of the treated root, abscess formation

- ੇ. Conclusion
NovaBone-BBG is claimed to be substantially equivalent to PerioGlas and Biogran as a non-structural osteoconductive bone void filler for oral and craniofacial defects. Side-by-side comparative in vivo performance data were presented. Additional supporting in vitro data were supplied.
