Intended Use

BioMesh® Biodegradable GTR Barrier is intended for use in the surgical management and treatment of periodontal defects to aid in the regeneration and integration of tissue components in guided tissue regeneration procedures.

Device Story

BioMesh® Biodegradable GTR Barrier is a microporous, biodegradable membrane used in guided tissue regeneration (GTR) procedures. It is provided in various precut shapes and sizes, though surgeons may trim it to fit specific operative sites. The device is placed by a clinician during periodontal surgery to facilitate tissue regeneration and integration. It acts as a physical barrier to manage periodontal defects. The device is supplied sterile and is intended for single use only; it must not be resterilized. It is designed to be biocompatible and stable for 5 years.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by bench testing, including biocompatibility, toxicity, and tissue integration testing (BioMesh score 115 vs. Resolut score 110).

Technological Characteristics

Microporous membrane composed of polyglycolic acid coated with polylactic acid + polylactic glycolic acid copolymer. Features interconnective pores and an embossed surface. Supplied sterile via terminal EtO sterilization. Complies with various voluntary standards including USP, ASTM, and ISO 9000 series.

Indications for Use

Indicated for treatment of two or three wall vertical defects, Class II furcations, circumferential defects, recession type defects, and dehiscence defects associated with dental implants.

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.
