Intended Use

OsSatura™ Dental is a bone filling augmentation material for used for augmentation or reconstructive treatment of alveolar ridge. This includes, filling of defects after root resection, apicoectomy and cystectomy, filling of extraction sockets to enhance preservation of the alveolar ridge and elevation of maxillary sinus floor.

Device Story

OsSatura™ Dental is a synthetic, osteoconductive bone void filler composed of a biphasic ceramic (hydroxyapatite/tri-calcium phosphate) scaffold. The device features an interconnected, open porous structure mimicking human cancellous bone, provided as 1-2 mm irregular chips. It is used by dental clinicians to fill bony defects, preserve extraction sockets, and elevate the maxillary sinus floor. The scaffold acts as a passive osteoconductive matrix, providing a physical environment that supports natural bone ingrowth and is gradually resorbed by the body over time. The device is supplied sterile for single-patient use.

Clinical Evidence

No human clinical trial data provided. Evidence consists of pre-clinical animal studies demonstrating bone ingrowth into bony defects and successful resorption of the material over time. Biocompatibility and bench testing confirm the device meets FDA guidance requirements for bone void fillers.

Technological Characteristics

Biphasic ceramic scaffold (hydroxyapatite/tri-calcium phosphate). Materials meet ASTM F1185-88 and F1088-87. Form factor: 1-2 mm irregular chips. Porous, interconnected structure. Osteoconductive. Sterile, non-pyrogenic, single-use.

Indications for Use

Indicated for augmentation or reconstructive treatment of the alveolar ridge in patients requiring bone void filling, including defects post-root resection, apicoectomy, cystectomy, extraction socket preservation, and maxillary sinus floor 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.

Predicate Devices

• Interpore 200 porous hydroxyapatite (K860983)
• BioOss Collagen (K974399)

### DEVICE DESCRIPTION 4.

OsSatura™ Dental is a synthetic, osteoconductive bone void filler, which consists of a biphasic ceramic (e.g., hydroxyapatite/tri-calcium phosphate) scaffold. The interconnected and open porous structure of OsSatura™ Dental is similar in structure to human cancellous bone. OsSatura™ Dental is available as irregular shaped chips of size 1 - 2 mm.

## 5. INTENDED USE

OsSatura™ Dental is a bone filling augmentation material for used for augmentation or reconstructive treatment of alveolar ridge. This includes, filling of defects after root resection, apicoectomy and cystectomy, filling of extraction sockets to enhance preservation of the alveolar ridge and elevation of maxillary sinus floor.

## TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE 6.

The OsSatura Dental and the predicate devices are all similar in design, materials of construction and function. The OsSatura™ Dental product and the predicate devices are all made of calcium salts. The proposed and predicate devices are osteoconductive. The OsSatura™ Dental product and all the predicate devices provide an interconnected, porous scaffold and an environment for new bone ingrowth. All of the devices are provided sterile and non-pyrogenic for single patient use. The only difference between the proposed device and the predicate devices is that they are composed of different forms of calcium phosphate salts. These minor differences do not affect safety or effectiveness since they all carry out the same function. The safety and biocompatibility testing performed for calcium phosphates and the long history of safe clinical use for hydroxyapatite and tri-calcium phosphate products support the safe use of OsSatura™ Dental. The hydroxyapatite and tri-calcium phosphate in the OsSatura™ Dental meet the requirements in ASTM F1185-88 and F1088-87. Additionally, testing performed on the proposed device confirmed that OsSatura™ Dental meets the applicable requirements of the FDA guidance documents on bone void fillers.

## 7. TESTING

Prc-clinical animal data demonstrate that OsSatura™ Dental chips support bone ingrowth into a variety of bony defects. Biocompatibility, extensive bench and animal testing using OsSatura Dental have successfully been performed to confirm that the device is degraded and resorbed over time and allow bone ingrowth.

Calcium-based ceramic materials, including hydroxyapatite and tri-calcium phosphate, have been used in clinical practice for more than 25 years with no remarkable safety issues. The devices to which OsSatura™ Dental claims substantial equivalence Interpore 200 porous hydroxyapatite and Bio-Oss Collagen have been used safely for many years in the clinical environment.
