Nesting & preparation for printing
• Import STL file
• Manual/Automatic rotation and placement
• Optimal orientation: horizontal, occlusal plane facing the build platform
• Manual/Automatic generation of supports
Necessary tools, equipment and materials for post-processing
• Print removal tool
• Unheated ultrasonic bath
• Ethanol solution 96%
• Spray bottle with 96% ethanol solution
• Cutting wheel or side cutters (for support structure removal)
• Sandblaster 1.5 bar
• Glass bead blasting material 50 μm (e. g. Perlablast® micro, REF 46092/54302)
The ideal working temperature of VarseoSmile Crownplus is in the temperature range between 18°C and 28°C. Before use, the resin must be homogeneous. Before the first use, the material has to be
shaken well about 2 min. When decanting, make sure that the printing resin is exposed to
daylight for as short a period of time as possible. Mix the resin in the cartridge /resin tank if a
transparent layer is visible on the surface. For further processing – selecting the resin, material parameter, setting up the print job – as part of the printing process, follow the respective printer instructions for use.
Cleaning and preparation for post-curing
On completion of printing, the print objects are released from the build platform using the print removal tool. The print object should be cleaned in two steps with ethanol (96%) using an ultrasonic bath.
Precaution: Never fill ethanol directly into the ultrasonic bath; place it in the recommended container in the ultrasonic bath filled with water. Use an explosion-proof ultrasonic bath.
- Clean the print object for 3 min in a reusable ethanol solution (96%) using an unheated
- The precleaned object must be cleaned thoroughly for 2 min using a fresh ethanol (96%)
solution with the aid of an unheated ultrasonic bath.
- The print object is then removed from the ethanol bath and sprayed with additional ethanol (96%) in order to fully rinse off any remaining resin residue.
- Tip: Resin residues can also be removed using a brush soaked in ethanol (96%).
Precaution: The entire cleaning process should not take longer than 5 min as this could otherwise have a detrimental effect on the printed objects (swelling of the object with ethanol).
After cleaning, the print object is dried using compressed air under an extraction unit. If
there is liquid resin still adhering to the surface of the object, this can be completely removed
by spraying again with ethanol (96%) and re-drying.
Preparation for post-curing
- Remove the support structure with the help of a cutting wheel or side cutters.
- Remove the white layer using a glass bead blasting material 50 μm (e. g. Perlablast® micro) at a maximum blasting pressure of 1.5 bar.
- Check for fit and finish the objects completely. Finishing and contouring can be per-
formed using carbide cutter or diamond grinding stones.
The final properties of the printed object depend on the post-curing process. Please note the
assignment of the light curing device to the 3D printer of the approved system components.
The post-curing of the object is done without use of a model, then allow to cool for
3–5 minutes or until the object feels cool.
Use the ProCure for 2 cycles at 20 min at 20°C, rotating once after the first cycle is complete.
Precaution: If there is an interruption or failure in the post-curing device cycle, the printed
object should be not used until it has cured under a full cycle. Check the post-curing device
manual for use for how to properly resolve the post-curing device condition and then repeat
the post-curing cycle with the printed objects.
Supplementing of printed objects
Defects (e. g. missing contact points) can be supplemented with the resin or with commercially available composite veneering materials.
Supplementing with resin
- Blast the areas to be supplemented with aluminum oxide – pressure 1.5 bar and particle size 110 μm.
- Put some liquid VarseoSmile Crownplus on the object.
- Put it under light for a short time (5 flashes) in the BEGO Otoflash
- If more material has to be applied, put additional liquid VarseoSmile Crownplus on the last layer and then put it again under light for a short time (5 flashes) in the BEGO Otoflash.
- Final curing of the Objects by using the BEGO Otoflash for 2 x 1500 flashes or HiLite Power for 2 x 90 s.
Supplementing with veneering material
The printed objects can be supplemented with commercially available composite veneering
materials (e. g. VITAVM LC*, Vita Zahnfabrik, und VITAVM LC flow*, Vita Zahnfabrik). The
manufacturer's instructions for use must be observed.
Polish the surface of the objects with pumice stone and polishing compound. Avoid over-
heating of the restorations during polishing. Optimal surface quality is achieved by polishing after post-curing.
Tip: Optionally, the surface of the objects can be coated with light-curing glaze (e. g. Vita ENAMIC GLAZE *, Vita Zahnfabrik or GC OPTIGLAZE *, GC). Pay attention to the manufacturer`s instructions for use.
Instead of polishing the surface, the post-cured objects can also be individualized with
composite stains or veneering materials.
- Commercially available composite stain materials (e. g. VITA ENAMIC STAIN*, Vita Zahn-
fabrik and GC OPTIGLAZE Color*, GC) can be used for individualization of the post-cured VarseoSmile Crownplus restoration. The manufacturer's instructions for use must be observed. Individualization with veneering materials
- Commercially available composite veneering materials (e. g. VITAVM LC*, Vita Zahnfabrik and
VITAVM LC flow*, Vita Zahnfabrik) can be used for individualization of the restoration. The
manufacturer's instructions for use must be observed.
- Commercially available light-curing veneering composites can be used to attach the
post-cured veneer shells to the metal framework (e. g. VITAVM LC, VITAVM LC flow, Vita
Basic work steps
- Condition the surface of the metal framework.
- Cover the metal framework with opaquer.
- Sandblast the inside of the veneer shell and clean the veneer shell from dust.
- Inner surface conditioning of the veneer shell.
- Applying the veneering material to the inside of the veneer shell or the metal framework.
- Positioning of the veneer shell on the metal framework and remove the excess with a brush or an instrument.
- Carry out the polymerization according to the instructions of the veneering material manufacturer.
- Finally, the surface of the veneer shell should be polished or customized with composite stains (see section "Polishing" or "Individualization").
Fully cured objects made from VarseoSmile Crownplus can be easily cleaned and disinfected. Steam cleaning (e. g., with Triton SLA) is possible. Disinfection in the immersion bath (e. g. ethanol 96% or MD 520* impression disinfectant, Dürr Dental Co.) is also possible. Follow manufacturer's instructions.
Attachment to adhesive Titan abutment/Titan abutment
Commercially available adhesive luting materials (e. g. Panavia V5*, Kuraray Noritake) can be used for fastening the Crown to the adhesive Titan abutment / Titan abutment. The manufacturer's instructions for use must be observed.
Observe the following points when fixing the crowns on titanium adhesive bases:
- After the restoration is attached to the implant, a Teflon band is pressed into the screw
channel to close the screw channel.
- The screw channel is then closed with a composite (e. g. Tertric EvoCeram Bulk Fill*,
- The objects can be polished with commercially available composite polishers.
Attachment to tooth stump
The finished permanent restorations can be attached using self-adhesive cements (e. g. RelyX Unicem*, 3M Espe) or composite cement with a primer (e. g. Variolink Esthetic DC* and Monobond Plus*, Ivoclar Vivadent). Observe the instructions for use of the luting agent.
The cured, separated material (base plate, support structure) can no longer be used. Cured material can be disposed of as domestic waste. Unused resin or ethanol used for cleaning with resin residues must be disposed of via the local waste disposal authority or a hazardous waste collection point stating the safety data sheet.
