be observed before grinding and finishing the core build-up. The working
time of ideally mixed MultiCore HB material is around 1.5 to 2 minutes.
– Build up the composite core by applying MultiCore HB.
– If no light is used, wait for 4-5 minutes until the chemical curing process
is complete. If the material is light-cured, it may be ground immediately
after completing the curing cycle.
– Optionally, MultiCore HB may be cured for 20 s from all aspects (approx.
1200 mW/cm 2 , e.g. bluephase, HIGH-mode). The distance between the
light emission window and the occlusal surface must be kept at a minimum.
– Once MultiCore HB has set, use rotary instruments to complete the
crown preparation.
Adhesive cementation of glass fibre-reinforced composite root canal
posts and core build-ups using MultiCore Flow.
Pre-treatment of the root canal and the coronal dentin
– A dry operating field must be ensured. Ideally, a rubber dam should be
used, e.g. OptraDam Plus.
– Disinfect the prepared root canal (e.g. NaOCl, 5%) and dry with paper
points.
– Condition the root canal, the coronal dentin and the enamel surfaces
according to the instructions of the manufacturer of the dentin bonding
agent used (eg AdheSE DC or ExciTE F DSC).
– After applying the dentin bonding agent, make sure to remove all excess
material from the root canal using paper points.
– Do not light cure the bonding agent.
– Place matrix band around the tooth.
Adhesive luting using MultiCore Flow
– Clean and condition post surface according to the manufacturer's
instructions.
– Mix the components of MultiCore flow and apply the mixed material to
the post.
– It is not recommended to use a lentulo spiral for loading MultiCore Flow
into the root canal, as this will lead to the intermixing of bonding agent
excess and MultiCore Flow. As a result, the working time of MultiCore
Flow will be reduced, so that it may be impossible to push the post into
the desired position within the root canal.
– Seat the post into the root canal and hold it in place using slight pressure.
– Light-cure for 30 seconds from the occlusal aspect
(approx. 1200 mW/cm 2 , e.g. bluephase, HIGH-mode). The light emission
window should be positioned as close to the post as possible.
Core build-up using MultiCore Flow
– Apply MultiCore Flow as described above (Application of MultiCore
Flow) and light cure.
Additional notes
MultiCore HB and MultiCore Flow should be at room temperature when
processed. At lower temperatures (eg immediately after removal from the
refrigerator) it may be difficult to extrude and mix the material.
Warnings
– Unpolymerized MultiCore should not come in contact with skin, mucous
membrane, or eyes. Unpolymerized MultiCore may have a slight irritating
effect and may lead to a sensitization against methacrylates.
– Commercial medical gloves do not provide protection against the sensiti-
zing effect of methacrylates.
Storage
– Storage temperature: 2–8°C/36–46°F.
Storage stability can only be guaranteed if the material is stored at this
temperature.
– Leave the used mixing tip on the MultiCore Flow cartridge/syringe.
It serves as a seal.
– Close syringes and cartridges immediately after use.
– Shelf life: see date of expiration on label.
