What advantages does All-Bond 3 offer over other total-etch adhesives?
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
What is the difference between "Universal Primer" and All-Bond 3? Are both dual cure? Is it recommended to use All-Bond Resin with either of the two?
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 to not 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.
How many applications can I get from the All-Bond 3 total-etch bottles?
You should get approximately 230 applications from a set of All-Bond 3 bottles.
Do I need to refrigerate the All-Bond 3 total-etch bottles?
No, the bottles may be stored at room temperature (20°C/68°F - 25°C/77°F).
What is the shelf life of the All-Bond 3 total-etch bottles?
Do I have to shake the All-Bond 3 total-etch bottles prior to use?
What is the processing time of All-Bond 3 total-etch bottles?
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.
Is it necessary to agitate All-Bond 3 after applying?
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.
The instructions say to apply 1-2 coats, do I need 1 coat or two?
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 after application of the All-Bond 3 surface is not glossy, what should I do?
If the surface is not glossy, the tubules may not be thoroughly filled. Apply additional coats.
How many seconds does it take to cure All-Bond 3 with a halogen and LED light?
Can All-Bond 3 be light cured by LED?
Yes, the photoinitiator in All-Bond 3 is camphorquinone (CQ), which is compatible with all dental curing lights.
Can a different applicator be used?
You may use any other applicator that is ethanol resistant.
How thick is the adhesive layer of the All-Bond 3?
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.
May I use a separate desensitizer with All-Bond 3?
Although a 2 year clinical trial found this adhesive to have minimal postoperative sensitivity1, you may use a separate desensitizer with this adhesive.
Can I combine ALL-BOND 3 with self- and dual-curing luting materials?
Yes, All-Bond 3 may be used in combination with light- and dual-curing luting materials.
Can I apply ALL-BOND 3 on calcium hydroxide?
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.
Is the use of rubber dam required?
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.
What influence do the solvents have?
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.
Why does All-Bond 3 contain HEMA?
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.
