• Decision Date: Sep 15, 1998
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 872.3690
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

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.

Device Story

RENEW is a light-cured, radiopaque, universal hybrid composite restorative material. It consists of a barium glass and silica-filled ethoxylated Bis-GMA/UDMA dimethacrylate matrix. Used by dentists in clinical settings for cavity preparations and tooth structure restoration. The material is applied to the tooth and hardened via light-cure polymerization. It is designed for non-sticky handling, high polishability, and strength. It bonds micromechanically and chemically to dentin/enamel adhesive systems. The device provides a restorative solution for various cavity classes and aesthetic repairs, benefiting patients by replacing missing tooth structure and masking dental anomalies.

Clinical Evidence

No clinical data. Evidence consists of bench testing including diametral tensile strength (DTS) and flexural modulus testing per ISO 4049 and ADA #27, and biocompatibility (cytotoxicity) testing per ISO 10993-5.

Technological Characteristics

Light-cured, radiopaque hybrid composite. Materials: Barium glass and silica fillers in an ethoxylated Bis-GMA/UDMA dimethacrylate resin matrix. Filler content: 74% w/w. Average filler size: 0.7 µm. Standards: ISO 4049, ISO 10993-5. Energy source: External light-curing unit.

Indications for Use

Indicated for Class I, II, III, IV, V, and VI dental restorations, direct aesthetic veneers for masking stains/anomalies, core build-ups for missing tooth structure, and composite/porcelain repairs. Prescription use only.

Regulatory Classification

Identification

Tooth shade resin material is a device composed of materials such as bisphenol-A glycidyl methacrylate (Bis-GMA) intended to restore carious lesions or structural defects in teeth.

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.

# 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.
