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, elevation of maxillary sinus floor and treatment of periodontal defects.

Device Story

OsSatura™ Dental is a synthetic, osteoconductive bone void filler composed of a biphasic ceramic scaffold (hydroxyapatite/tri-calcium phosphate). The device features an open porous structure mimicking human cancellous bone and is supplied as irregular chips (200μm–2000μm). It is intended for use by clinicians in dental procedures to fill bony defects, facilitate bone ingrowth, and support alveolar ridge reconstruction. The material is resorbed over time as new bone forms. It is provided sterile for single-patient use.

Clinical Evidence

No clinical data provided. Evidence consists of pre-clinical animal studies demonstrating bone ingrowth and resorption, alongside biocompatibility and bench testing confirming compliance with FDA guidance for bone void fillers and ASTM standards (F1185-88, F1088-87).

Technological Characteristics

Biphasic ceramic scaffold (hydroxyapatite/tri-calcium phosphate). Materials meet ASTM F1185-88 and F1088-87. Porous structure; irregular chips (200μm–2000μm). Sterile, non-pyrogenic, single-use. Osteoconductive.

Indications for Use

Indicated for augmentation or reconstructive treatment of the alveolar ridge, including filling defects post-root resection, apicoectomy, and cystectomy; filling extraction sockets for ridge preservation; maxillary sinus floor elevation; and treatment of periodontal defects.

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)

## INTENDED USE ડ.

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, elevation of maxillary sinus floor and treatment of periodontal defects.

# 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 The proposed and predicate devices are are all made of calcium salts. 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 tricalcium 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

Pre-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
