Indications for Use

ADVENT™ is intended for direct or indirect class I, II, III, IV, V, and VI restorations and composite core build-up. ADVENT™ is also intended for composite restorations bonded to tooth structure, metal, composite, fiber-reinforced substructure, and porcelain.

Device Story

ADVENT™ is a highly filled (78.6% w/w) radiopaque dental composite system consisting of Dentin and Enamel components. It is used by dental professionals for direct or indirect restorations (Class I-VI) and core build-ups. The material is a silica and glass-filled dimethacrylate hybrid composite. It is applied to the tooth and can be cured via light, heat, or a dual-cure process in a dedicated device (pressurized, oxygen-free nitrogen atmosphere). The material's high viscosity allows for sculpting and shaping. It is designed for use with high-quality dentin/enamel adhesive systems. The device benefits patients by providing a restorative material with high wear resistance, tensile strength, and compressive strength, facilitating effective tooth structure replacement and bonding to various substrates.

Clinical Evidence

Bench testing only. Performance evaluated via ISO 4049 and ADA #27 standards for dental resin-based filling materials. Diametrial tensile strength (DTS) testing showed ADVENT™ Dentin (65 MPa) and Enamel (55 MPa) compared to belleGlas™ Dentin (63 MPa) and Enamel (57 MPa). Biocompatibility (cytotoxicity) performed per ISO 10993-5 by NAMSA confirmed non-toxicity.

Technological Characteristics

Silica and glass-filled dimethacrylate hybrid composite. Radiopaque. Dual-cure (heat/light) polymerization. High viscosity for sculpting. Complies with ISO 4049 and ADA #27 standards. No software or electronic components.

Indications for Use

Indicated for direct or indirect class I-VI dental restorations, composite core build-up, and bonding to tooth structure, metal, composite, fiber-reinforced substructure, or porcelain.

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.

### SUMMARY

### Leqally Marketed Predicate Device belleGlas™ HP

The belleGlas™ HP system includes a Dentin and Enamel component. The Dentin component is engineered for high physical and mechanical strength and the Enamel component is formulated for high resistance to wear and abrasion. Both components are highly filled, radiopaque composites designed for indirect restorations. The belleGlas™ HP composites are cured by light, heat, and pressure in a dedicated device.

## Description of A plicant Device ADVENT™

The ADVENT™ system is also comprised of a Dentin component and an Enamel component. ADVENT Dentin is a highly filled (78.6% w/w) composite designed for class I. II. III. IV. V. and \1 restorations and composite core build-up. ADVENT™ Enamel is a highly filled composite which, like belleGlas™ Enamel, is designed for high resistance to wear and abrasion as well as good polishability. Both Dentin and Enamel components are radiopaque and pclymerizable by a dual cure system (heat/light), i.e., can be light cured by conventional mear s or processed in a dedicated curing device that employs heat and light in a pressurized, cxvaen-free nitrogen atmosphere. The ADVENT™ system is designed to be used with hich quality dentin/enamel adhesive systems.

## Intended Uses of Applicant Device ADVENTTM

ADVENT™ is intended for direct or indirect class I, II, III, IV, V, and VI restorations and composite core build-up. ADVENT™ is also intended for composite restorations bonded to tooth structure, metal, composite, fiber-reinforced substructure, and porcelain.

# Scientific Conce its and Significant Performance Characteristics

The ADVENT™ and belleGlas™ HP systems are very similar with regard to chemical composition and selected physical/mechanical properties. Significantly, belleGlas™ HP and ADVENT™, following curing, have been designed to have increased wear resistance, tensile strength, and compressive strenath. These properties are essential to a composite in order for it to function effectively. The highly viscous nature of belleGlas™ HP and ADVENT™ allows them to be easily sculpted and shaped.

The chemical compositions of belleGlas™ HP and ADVENT™ are quite similar. Both are silica and glass fillers dimethacrylate hybrid composites. Both can be cured by heat, light, and pressure in dedicated devices.

The non-clinical tes s used for this submission are similar to those specified in ISO 4049 and American Dential Association #27: both are for dental resin based filling materials. Diametrial tensile strength (DTS) is an accepted method to characterize the tensile strength of trittle materials. DTS of ADVENT™ Dentin and belleGlas™ Dentin are, respectively, 65 and 63 MPa. DTS of ADVENT™ Enamel and belleGlas™ Enamel are, respectively, 55 and 57 MPa.

Biocompatibility of ADVENT™, cytotoxicity, was performed per ISO 10993-5 by a commercial testing laboratory (NAMSA) and the product was found to be non-toxic.

Comparison of ADVENT™ to the predicate device illustrates that the two items are very similar. The major difference between the two systems is in the intended uses. ADVENT™ may be used for direct as well as indirect restorations. The predicate device is designed specifically for direct restorations only.
