Frequently Asked Questions

All Infinix™ products contain Nobio™ QASi Antimicrobial technology, which has a unique formulation. QASi consists of Quaternary Ammonium particles (very strong antimicrobial agent) covalently bound to silica. This unique formulation allows for the QASi, once incorporated into the composite, to be non-soluble, non-releasing and non-leaching. The particles electrostatically attract bacteria and disrupt their membrane, killing them on contact rather than by chemical release or exchange.

Fluoride antibacterial products, on the other hand, rely on releasing a chemical (fluoride) which diminishes over time thus reducing its level of antibacterial efficacy.

Formation of biofilm is a well-recognized phenomenon in the use of composite for dental restoration which results from leakage of saliva into micro gaps that form at the restoration-tooth interface. Bacteria invade the space, and with appropriate conditions (sugar, nutrients, cariogenic strains) secondary caries will propagate.

When using Infinix™ Antimicrobial products, the bacteria that enter the space are killed and no metabolic pH fluctuation can occur. Thus, there is no formation of biofilm under the restoration.

Since Nobio’s QASi Antimicrobial particles are covalently bonded to the fillers that are embedded into the restorative materials, they do not leach out and are not released, therefore they are designed to last as long as the life of the restoration. Note: The lifetime of the restoration is dependent on several variables – i.e. home care, oral behaviors, etc.

No. Since the QASi Antibacterial particles are homogeneously embedded within the materials, there are no implications of such procedures on the antibacterial effect.

Yes. Infinix™ Universal Bond is a resin-based bond system consisting of a self-etch primer and a light-cured bond. Nobio™ QASi technology is incorporated into the Universal Bond, transforming it into an ultra-powerful and innovative bonding agent that protects the tooth restoration interface against metabolically active bacteria.

Infinix™ products are intended for all genders and patients of all ages and provide an effective solution for all patients.

Infinix™ can support fighting secondary caries within “high-risk” caries patients. That would include patients with dry mouth (xerostomia), patients with poor home care, high prescription medicine users, diabetic patients, pediatric patients, etc.

The Infinix™ Flowable Composite can be used as base and combined with another composite on top of it. It is highly recommended to use the Infinix™ Universal Composite for better compatibility and performance.

Infinix™ Composites cannot be used with a single bottle/1-step bonding agent. The chemistry is not compatible and will result in poor bond strength.

Limited testing has been performed. We have successfully tested our material with TheraCal (Bisco). There was no interference with the polymerization and the shear bond strength was above 16 MPa.

To minimize post-operative sensitivity, it is recommended to follow the manufacturer's instructions (IFU and Step-By-Step Procedure Guide).

The procedure steps are similar to other products on the market. There is no significant learning curve.

Curing times depend on the product and light intensity. Our products are designed to be cured by exposure to a halogen or LED light with a minimum intensity of at least 1000 mW/cm2 in the 430-490 nm range.

Curing times for the Infinix™ Flowable Composite is 10 sec and for the Infinix™ Universal Composite is 20 sec.

The application layer thickness using the recommended curing is up to 2mm.

The shelf life is two years from date of manufacture.

These products are designed to be stored and used at room temperature and not refrigerated. Ambient temperatures routinely higher than 25°C/77°F may reduce shelf life.

Infinix™ Products all have very solid & good physical properties. They compare very well against the leading materials in the field. Specific details are listed on the Product Pages for each product on the Infinix™ website - www.infinix.com.

Yes, all Infinix™ Products contain some version of Bis-Phenol A in the form of Ethoxylated Bis-phenol A dimethacrylate and Bis-phenol A glycidyl methacrylate.

Yes.

≥60%

10-MDP improves the hydrolytic stability of the material over time as well as improving the bonding strength to enamel.

Infinix™ Universal Bond is a two-step self-etching primer and bonding agent adhesive system.

If the treatment chosen is an acid-etching technique, phosphoric acid should be applied (according to the manufacturer's instructions). Selective Enamel Etching technique is recommended.

Nano-Hybrid filler particle size: 40 nm-3μm (contains QASi antibacterial nano fillers).

Radiopacity (%Al): 237%

The radiopacity is well above the required standard due to the unique glass fillers that contain Barium.

This property allows the clinician to distinguish between Infinix™, the tooth and other materials to determine the quality of the restoration.
