All-Bond 3® Part A&B Set

The term "total-etch" is used for simultaneous etching of enamel and dentin with phosphoric acid to remove the smear layer and to obtain micro-porosities for the integration of the bonding agent. The etching should start with enamel and then move to dentin. BISCO recommends a 15 second etch as a general guideline. Excessive etching of dentin may cause hypersensitivity and incomplete hybrid layers.

BISCO Etchant was made into a semi-gel form using a polymer thickening agent rather than conventional submicron silica etching gels. Conventional silica etching gels have been shown to leave submicron silica debris, following rinsing, on the etched surface.

It is critical to keep the prepared dentin moist. Wet (moist) bonding is desirable because it prevents exposed collagen fibers from collapsing. For total hybridization and optimal bond strength, these exposed collagen fibers must be infiltrated and saturated by the primer/adhesive. The saturation is confirmed clinically by observing a glossy surface of primer/adhesive after thorough evaporation of the solvent. Over dried collagen leads to the formation of a dense amorphous layer that may impede infiltration of the primer/adhesive solution into the intertubular dentin and results in incomplete hybridization.

Air drying is not recommended. Air drying may collapse collagen fibrils while incorporating air into the dentinal tubules with possible cause of postoperative sensitivity. High volume suction removes pooled water and allows for collagen fibrils to remain sufficiently hydrated, facilitating primer infiltration. Alternatively, an absorbent pellet may be used to blot pooled water from the dentin.

• One-layer adhesive, yet as durable as 2-layer adhesive systems
• Universal compatibility with all materials (light- , dual- and self-cure) to all substrates
• Minimized post-operative sensitivity¹
• Cross-linking monomers eliminate the need for a hydrophobic bonding resin layer
• Simple application technique for all procedures

Universal Primer is a 2-part, dual-cure system that can be used in total-etch, self-etch or selective-etch technique. It is recommended for the clinician who prefers not to light-cure under indirect restorations. All-Bond 3 is also a 2-part dual cure system but can only be used in total-etch mode. You may use All-Bond 3 Resin with either of the two adhesives for radiopacity to outline the restoration, and reduce the risk of misdiagnosing caries.

You should get approximately 230 applications from a set of All-Bond 3 bottles.

No, the bottles may be stored at room temperature (20°C/68°F - 25°C/77°F).

No

All-Bond 3 is a dual-cured adhesive. Use All-Bond 3 adhesive shortly after it is dispensed in the mixing well to prevent polymerization, protect from ambient light.

Agitating the adhesive on the tooth is beneficial, we recommend applying the adhesive onto the entire tooth preparation with a light agitating motion for 5-10 seconds.

Smaller preparations may require only 1 coat/application, larger preparations may require 2+ coats/applications (consecutive applications with no air drying or waiting). After evaporation the adhesive will have a glossy appearance.

If the surface is not glossy, the tubules may not be thoroughly filled. Apply additional coats.

Yes, the photoinitiator in All-Bond 3 is camphorquinone (CQ), which is compatible with all dental curing lights.

You may use any other applicator that is ethanol resistant.

The film thickness of All-Bond 3 is only 5-10µm. This makes the adhesive ideal for use under all indirect restorations. Additionally, light curing is optional for added confidence of a perfect restoration fit.

Although a 2 year clinical trial found this adhesive to have minimal postoperative sensitivity¹, you may use a separate desensitizer with this adhesive.

Yes, All-Bond 3 may be used in combination with light- and dual-curing luting materials.

Yes, you may use this adhesive over calcium hydroxide, some of the calcium hydroxide will slightly dissolve during the etching step. We strongly recommend the use of TheraCal LC®, BISCO’s light-cured Resin-Modified Calcium Silicate Pulp Protectant/Liner.

Isolation from contamination is essential. If this is ensured, the use of rubber dam may not be required in certain cases, decided by the clinician. Nevertheless BISCO recommends the use of a rubber dam in any case.

The technique to be used depends on the solvent. In the case of All-Bond 3 which is ethanol based, better bond strength performance is demonstrated when the dentin is mildly wet. Ethanol has a higher ability to re-expand collapsed collagen fibrils as compared to acetone-based adhesives. Ethanol requires more time for evaporation than acetone which can be facilitated with agitation upon placement. Incomplete evaporation causes deficient polymerization and could potentially lead to failures.

HEMA is a hydrophilic monomer that is a good wetting agent and penetrates easily into the tooth surface. One of the drawbacks with HEMA is that it firmly retains water in adhesives, from where it is hardly removed by air-drying. All-Bond 3 is water-free and ethanol based to allow for a reduction in the HEMA content and the inclusion of more hydrophobic, highly cross-linking monomers.
