Device Story

BIO-GIDE® is a resorbable bilayer membrane for guided tissue and bone regeneration in dental applications. Composed of purified porcine collagen (Type I and III) without cross-linking or chemical treatment. Bilayer structure features a porous surface for bone-forming cell ingrowth and a dense surface to prevent fibrous tissue infiltration. Used by dental clinicians during surgical procedures to facilitate bone and tissue healing. Device acts as a physical barrier to guide regeneration. Sterilized via gamma irradiation. Manufacturing process includes a validated heating step (70°C for 30 minutes) to ensure destruction of potential pathogens, meeting USDA requirements.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by bench testing and validation of the revised manufacturing process (heating step) to ensure it does not alter the product's physical or biological characteristics.

Technological Characteristics

Resorbable bilayer membrane; material: porcine-derived collagen Type I and III; no cross-linking or chemical treatment. Bilayer structure: porous side for bone ingrowth, dense side for soft tissue exclusion. Sterilization: gamma irradiation. Manufacturing includes 70°C heating step for 30 minutes.

Indications for Use

Indicated for patients requiring guided bone or tissue regeneration in dental procedures, including implant placement (immediate or delayed extraction sockets), ridge augmentation, alveolar reconstruction, and treatment of periodontal or bone defects (dehiscence, root resection, cystectomy, tooth removal).

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.

BIO-GIDE® is recommended for:

- Simultaneous use of GBR-membrane (BIO-GIDE®) and implants; .
- Augmentation around implants placed in immediate extraction sockets; �
- Augmentation around implants placed in delayed extraction sockets; .
- Localized ridge augmentation for later implantation; .

#### DEVICE DESCRIPTION ട്.

BIO-GIDE® resorbable bilayer membrane for guided tissue and bone regeneration. BIO-GIDE® is a pure collagen membrane obtained by a standardized controlled manufacturing process. The collagen is extracted from veterinary certified pigs and is carefully purified to avoid antigenic reactions. BIO-GIDE® is sterilized in double blisters by gamma irradiation. BIO-GIDE® has a bilayer structure. The porous surface facing the bone - allows the ingrowth of bone forming cells. The dense surface - facing the soft tissue - prevents the ingrowth of fibrous tissue into the bone defect. The

{1}------------------------------------------------

membrane is made of collagen type I and type III without further cross-linking or chemical treatment.

#### BASIS FOR SUBSTANTIAL EQUIVALENCE 6.

BIO-GIDE® resorbable bilayer membrane for guided tissue and bone regeneration is BIO-OIDE® Tesorbable onayst livel's existing product, BIO-GIDE® K960724 and Substantially cquiratelle to Gebarent on the new product and the BIO-GIDE® product K042197.

Dear Mr. Reichertz:

This letter corrects our substantially equivalent letter of August 9, 2005.

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
