Device acts as a physical barrier to prevent apical migration of gingival epithelium into periodontal defects during ligament regeneration. Provided sterile in various sizes/shapes with affixed bioabsorbable ligatures. Used by dental surgeons during periodontal procedures. Unlike the predicate GORE-TEX material, the device is bioabsorbable and does not require surgical removal post-implantation. Benefits include temporary support during healing and elimination of a second procedure for barrier removal. ## Clinical Evidence Clinical and preclinical evaluations were conducted to assess safety and effectiveness. Analytical characterization included thermal properties and molecular weight assessment. Clinical data supported the device's function as a barrier for periodontal defect healing. ## Technological Characteristics Synthetic, bioabsorbable copolymer of glycolide and lactide (polyglactin 910). Woven mesh construction. Provided sterile. Includes affixed bioabsorbable ligatures. Bioabsorbable nature eliminates need for post-implantation removal. ## Regulatory 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 - GORE-TEX Periodontal Material ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Paulson, Ph.D. Vice President, Regulatory Affairs Ethicon, Incorporated Route 22 West Somerville, New Jersey 08876 Re: K955646 Trade Name: Vicryl Peridontal Mesh Regulation Number: 872.3930 Regulation Name: Bone Grafting Material Regulatory Class: 2 Product Code: NPK Dated: March 27, 1996 Received: March 28, 1996 Dear Dr. Paulson: This letter corrects our substantially equivalent letter of May 20, 1996. 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. {1} Page 2 – Please be advised that FDA’s issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act’s requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to continue marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97).
