Irving Park Road Schaumburg, IL 60193 SH 22 of 25 As Required by 21 APPLICANT DEVICE Trade Name: RENEW™M Common Name: Composite Restorative Material Classification Name: Tooth Shade Resin Material, Class II, 21 CFR 872.3690 LEGALLY MARKETED PREDICATE DEVICE: AELITEFIL™ PREDICATE DEVICE AELITEFIL AELITEFIL, universal hybrid composite, is a highly filled (75% by wt.), light cured hybrid composite restorative material is radiopaque and indicated for all types of cavity preparations. The hybrid blend of ultra fine primary filler (averaging 0.7 µm with tightly controlled distribution) and submicron silica results in superior optical qualities and physical/mechanical properties. The material bonds micromechanically and chemically to dental primers/bonding resin adhesives through co-polymerization of the former's air inhibited layer. AELITEFIL is designed to be marketed as a stand alone product. DESCRIPTION OF APPLICANT DEVICE RENEW RENEW, universal hybrid composite, is a highly filled (74% w/w), light-cured radiopaque hybrid composite. Its physical/mechanical properties are similar to the predicate device and uses are identical. Like the predicate device, RENEW is barium glass and silica filled dimethacrylate composite. It hardens by light cure polymerization mechanism employing light activated initiators. Both devices are designed to be used with high quality dentin/ enamel adhesive systems. INTENDED USES OF APPLICANT DEVICE RENEW RENEW is indicated for: Class I, III, IV, V and VI restorations, direct aesthetic veneers for masking stains and developmental anomalies, core build ups to replace missing tooth structure and composite/ porcelain repairs. {1}------------------------------------------------ 510(k) Submission for RENEW™M BISCO, INC., 1100 W. Irving Park Road Schaumburg, IL 60193 SH 23 of 25 # 510(k) SUMMARY (cont.) ### SCIENTIFIC CONCEPTS and SIGNIFICANT PERFORMANCE CHARACTERISTICS AELITEFIL and RENEW are very similar with regard to chemical composition and selected physical/mechanical properties. Significantly, AELITEFIL and RENEW have been designed to achieve 'Non-Sticky' handling before cured as well as high polishability and strength when cured. These properties are desired of restoratives to be indicated for all types of cavity preparations. The hybrid blend of ultra fine primary filler (averaging 0.7 µm with tightly controlled distribution) barium glass, and silica results in high strength and polishability of cured AELITEFIL and RENEW. The Bis-GMA and UDMA monomers of AELITEFIL are balanced to achieve 'Non-Sticky' handling. RENEW is based on the the ethoxylated version of Bis-GMA resulting in reduction of 'stickiness' even more. The chemical compositions of AELITEFIL and RENEW are quite similar. Both are barium glass and silled methacrylate hybrid composites. Both are light cured, and radiopaque for easy radiographic identification and evaluation. The non-clinical tests used for this submission are similar to those specified in ISO 4049 and American Dental Association \$27; both are for dental resin based filling materials. Diametral tensile testing (DTS) is an accepted method to characterize the tensile strength of brittle materials and the flexural modulus test addresses the strength in three point loading. DTS values are 45 and 50 MPa for AELITEFIL and RENEW respectively. Biocompatability of RENEW, Cytotoxicity, was tested in conformance with good laboratory practice and EN 45001 (ISO 10993-5) by a commercial testing laboratory (NAMSA) and the product was found to be non-toxic. Side by side comparisons of RENEW to the predicate device provided in this submission clearly demonstrated that the applicant device, RENEW, is substantially equivalent to the legally marketed predicate device, AELITEFIL, in terms of effectiveness or suitability to the intended uses.

Irving Park Road Schaumburg, Illinois 60193 K982729 Re : RENEW™ Trade Name: Requlatory Class: II Product Code: EBF Dated: August 3, 1998 Received: Auqust 5, 1998 Dear Dr. Joung: We have reviewed your Section 510 (k) notification of intent to market the device referenced above and we 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). 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 (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Requlations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP requlation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Reqister. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 {4}------------------------------------------------ Page 2 - Dr. Joung through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or requlations. This letter will allow you to begin marketing your device as described in your 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.
