What is the difference between ALL BOND 2 and ONE-STEP?
  ALL BOND 2:
  • 4th generation bonding system
  • Multi-bottle system
  • Double bottle primers
  • Double bottle unfilled resins
  • Dual cured

ONE-STEP:
  • 5th generation bonding system
  • Single bottle system
  • Primer and unfilled resin in one bottle
  • Light cured

   
What are the bonding strengths of ALL BOND 2 vs. ONE-STEP?
 
Substrate ALL BOND 2 ONE-STEP
Enamel 29 MPa 28 MPa
Dentin 30 MPa 27 MPa
Treated Porcelain 17 MPa 24 MPa
Amalgam (D/E RESIN + PREBOND)
9 MPa
 
Amalgam (+ RESINOMER) 12 MPa 10 MPa
Metal 24 MPa 24 MPa
   
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 main difference between BISFIL 2B and BISFIL II?

Barium;
Fumed Submicron Silica
   
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 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.
   
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 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.
