What makes ONE-STEP unique? |
| |
- ONE-STEP is the only “One Bottle Bonding System” that bonds to each
substrate in dentistry, providing bond strengths greater than 20 MPa. Moreover,
ONE-STEP is the only 5th generation light-cured system which bonds to self-cured
composites and cements.
- ONE-STEP (in conjunction with any of BISCO cements) can be used for bonding
indirect restorations such as inlays, onlays and crowns. It cures at a very low
film level (12 μm).
Additionally, all BISCO cements cure with a film
thickness as low as 20 μm and when used along with ONE-STEP do not interfere
with the seating of the indirect restoration. |
| |
|
|
How does ONE-STEP work under self-cured or dual-cured cements and composites? |
| |
After light-curing ONE-STEP an oxygen inhibited layer forms. This layer contains methacrylate groups which will chemically react with the self-cured composite once the contact with oxygen is blocked.

How does AQUA PREP work? |
| |
AQUA PREP’ s main ingredient is HEMA in a water solution. When applied on the dentin surface, the water is not easily evaporated because of HEMA’ s ability to hold water molecules through hydrogen bonding. The preparation remains moist and ensures an adequately wet surface for bonding primers to completely penetrate dentin tubules. At the same time the HEMA solution is able to render a temporary desensitizing effect. For permanent desensitization, a subsequent layer of an acetone based adhesive must be applied to the HEMA-filled dentin and polymerized. |

What is the difference between CORE-FLO and BIS-CORE? |
| |
CORE-FLO has been designed to be a fast- setting, syringeable chemical-cured composite. It sets in about 2.75 min, which is less than BIS-CORE (5 min).
BIS-CORE is a packable and sculptable composite. It can be light-cured or dual- cured when the base paste is mixed with the catalyst, which serves as a viscosity modifier as well. |
| |
|
|
What is the difference between AELITEFLO and AELITEFLO LV? |
| |
Both composite materials have the same resins and initiation systems. The main difference is the amount of filler – AELITEFLO is 60% filled by weight (with 0.7 microns barium + submicron filler), whereas AELITEFLO LV is 55% filled with the same filler. Less filler gives LV a lower viscosity. |

Which BISCO’ s cement should be used for what restoration? |
| |
| Luting Cement |
Indications |
| C&B Luting Cement Opaque |
Single unit metal crowns, Maryland bridges or post bonding |
| C&B Luting Cement Natural |
Multi-unit porcelain/composite inlays, onlays or crowns |
| RESINOMER |
Metal based restorations, amalgam bonding, liner, orthodontic band and
bracket bonding, Maryland bridges or post cementation |
| DUO-LINK |
Porcelain and composite inlays, onlays and crowns
Can also be used for
metal based restorations and post bonding |
| CHOICE |
Designed for aesthetic luting procedures |
| ILLUSION |
Aesthetic luting cement based on the value of the shade
Light-cured:
Veneers
Dual-cured: Porcelain and composite inlays, onlays and crowns |
|
| |
|
|
What is the difference between ILLUSION and CHOICE? |
| |
CHOICE Luting Cement comes in prefabricated VITA shades + 1 translucent shade. There is little to no opportunity to modify the value and chroma of the indirect restoration or to block strong underlying discolorations.
The principle of using ILLUSION is totally different from that of CHOICE. With ILLUSION the practitioner can easily modify the value of the restoration, making it brighter or darker using one of the dual- cured BASE PASTES.
The hue can be warmed (i.e. changed from A1 to A2) using the COLOR MODIFIER, which corresponds to A4 VITA shade. PINK BLOCK-OUT PASTE helps to neutralize strong stains on the tooth surface.
The ILLUSION kits contains less components than CHOICE, but despite that it provides more shade options.

Why is MICRONEW a reinforced microfill? |
| |
MICRONEW, with its average particle size of 0.05 μm, contains predominately sub-micron (0.04 μm) filler particles. It has as well a small percentage (about 20%) of 1 μm strontium glass particles added for strength.
On the other hand, hybrid composite materials (having average filler particle size between 0.6 μm and 1.0 µm) contain about 60% big glass particles. |

What is the reason for the particular two stage design of C-POST, AESTHETI-PLUS and LIGHT-POST? |
| |
BISCO’ s posts feature a two-stage design, which
provides:
- More secure seating of the post within the root canal, preventing the
possibility of root perforation.
- More even distribution of the external forces on the walls of the root canal
– the first stage distributes the forces on dentin evenly and the second stage
reduces stress on the radicular portion of the tooth, eliminating cracks and
fractures caused by the selective concentration of stress.
|
| |
|
|
What is the difference between LIGHT-POST and AESTHETI-PLUS? |
| |
The LIGHT-POST system is completely translucent, so that the shade of the post does not interfere with the shade of the final restoration. It should be used where maximum translucency is needed.
AESTHETI-PLUS on the other hand is coloured corresponding to VITA A2 shade which is the universal shade for most aesthetic restorations. |

|
Can I use HI-X luting cement for cementing crowns? |
| |
You sure can; however, HI-X has been designed to be extremely radiopaque at very low film levels, in order to provide radiopacity to carbon- or quartz-fibred posts.
Therefore, HI-X has been specifically formulated for post luting procedures where the shade of the cement is not a principal concern. |
| |
|
|
Do I need to apply the PREBOND resin (a component of ALL BOND 2 kit) when bonding HI-X to the walls of the canal? |
| |
We do not recommend using PREBOND with HI-X cement. HI-X is a very radiopaque cement, and the PREBOND can displace the cement thus reducing the visibility of the cement on X- rays. Using PREBOND with HI-X will not increase or decrease the bond strength, but placing PREBOND in the canal has the potential to thin out the HI-X and thus not be as easily visualized on the peri-apical X- ray. It is very important as well that HI-X cement fill the whole space without any unfilled resin around the post. |

What is COMPOSITE ACTIVATOR? What is it used for? |
| |
COMPOSITE ACTIVATOR is a methyl methacrylate dissolved in solvent. It is used to “wet” the surface of the composite following sandblasting, which lowers the surface tension. This is to achieve a better bond to the new composite material or the resin cement. |
| |
|
|
Why is porcelain repair a “problem” procedure? |
| |
Porcelain repairs are very “technique sensitive” and the procedure for addressing those kinds of cases is different from regular bonding procedures. There are several things that must be followed for optimal results; sandblasting, hydrofluoric acid, silane (within shelf life!) and proper isolation.
The first step is to sandblast the porcelain surface before beginning the repair.
Hydrofluoric (HF) acid treatment of the existing porcelain will yield a stronger bond than micro-etching the porcelain. It is strongly recommended that HF acid be left for 3-4 minutes to etch the porcelain properly.
If the existing is one of the newer types of porcelain, such as PROCERA or INCERAM, HF acid will not work because these types of porcelain have a very minimal glassy phase within the crystalline structure.
Rinse and dry the surface thoroughly – the porcelain bonding rationale requires a completely dry surface.
The next step is to apply silane on the porcelain surface and proceed with placing the composite increment.
Be sure to place a long bevel in the porcelain around the repair. This will increase the surface area for bonding repair. |

What is FORTIFY PLUS? |
| |
Essentially, FORTIFY PLUS is a flowable, microfilled composite surface sealant. It has been 30% filled by weight with submicron filler. FORTIFY PLUS cures with average film thickness of 20-25 µm, however, it is strongly recommended that FORTIFY PLUS be air-thinned after applying it to the composite surface. |
