The new Venus Bulk Flow ONE offers an one-shade solution within the Venus family for basic posterior restorations. With its incredible shade-matching properties, Venus Bulk Flow ONE blends seamlessly into the surrounding dentition, independent of the tooth shade – even when used for bulk-filling cavities of up to 4 mm.
Venus Bulk Flow ONE combines the self-levelling effect of a flowable material with a high curing depth and good stability after application. This allows to place increments of up to 4 mm inside a cavity. With Venus Bulk Flow ONE dentists can reduce treatment time without the need for shade selection or the placement of a universal composite as an additional capping layer. With its range of indications from bulk filling through cavity lining to fillings in primary teeth, the efficient restoration procedure is further enhanced by the equally reliable and versatile bonding solution iBOND Universal.
Low shrinkage stress and high flexural strength ensure durable restorations. High wear resistance allows Venus Bulk Flow ONE to withstand high mastication loads in the posterior region.
Venus Bulk Flow ONE meets the ISO 4049 recommendation for flexural strength in posterior cavities also after accumulated thermal aging.
Venus Bulk Flow ONE eases x-ray diagnostics.
Venus Bulk Flow ONE is suitable to restore occlusal surfaces in posterior teeth.
Venus Bulk Flow ONE has low shrinkage stress.
Venus Bulk Flow ONE can be used in 4 mm layers.
Venus Bulk Flow ONE can be used for the restoration of occlusal surfaces in posterior teeth.

This lower left first molar (36) has had an amalgam restoration for many years, showing marginal gapping and hairline cracks surrounding the filling material.
After placement of the rubber dam, the amalgam restoration was removed with burs and appropriate water cooling. The cavity shows visible secondary caries.
The cavity was then disinfected with 20% Chlorhexidine for 2 minutes.
The cavity margins were treated with a 27-micron Aluminum Oxide blasting (Air Abrasion) to remove stains from the previous restoration.
Selective enamel etching was done with orthophosphoric acid.
The tooth was rinsed and dried without drying out the dentin. A paper pellet was placed inside the cavity to obtain dry enamel and with the dentin retaining a certain degree of moisture.
Due to the depth of the cavity the decision to use Kulzer's iBOND Universal was made. The used selective enamel etching technique allows proper adhesion for dentin and enamel likewise without the risk of over etching the dentin.
A thin layer of Venus Bulk Flow ONE was placed as a base inside the cavity and light cured. Afterwards Venus Pearl ONE, a monochromatic, pasty composite was applied incrementally to build up the restoration.
Oblique increment recreating the buccal triangular ridges was placed first and then light cured.
The final increment was placed, and light cured, rebuilding the palatal triangular ridges.
An air-blocking gel was applied on the finished restoration and the restoration was light cured through it. This way a composite surface without an inhibition layer was obtained. This enables the curing of the deepest part of the grooves that were created.
Final image after reconstruction with Venus Pearl ONE and polishing with Venus Supra. An aesthetically pleasing restoration with universal composite was achieved.
Very small, recently placed ceramic inlays on teeth 14 and 15. Tooth 15 showed persisting pain when the patient bit down, as well as a highly increased sensitivity to cold. The suspected diagnosis was an infraction of tooth 15.
After the removal of the ceramic inlay on tooth 15, there was no infraction line, instead there wasa very deep cavity reaching close to the pulp without any caries.
The first layer in the proximal box and in the extended occlusal fissure, was created with Venus Bulk Flow ONE in "classic" flow layer thickness of 1-2 mm.
Venus Pearl in the self-adapting colour ONE was then used as a capping layer.
The finished and polished new restoration of tooth 15 at a follow-up visit after 6 weeks. The discomfort already significantly reduced in the meantime.
1. When is Venus Bulk Flow ONE recommended to be used with or without capping layer?
Using Venus Bulk Flow ONE without capping layer is beneficial in all clinical cases where a flowable viscosity is ideal during placement, e.g. slot or small cavities or those with tunnel preps, class III restorations with intact labial wall or class V restorations. From a patient per-spective, Venus Bulk Flow ONE is furthermore ideal in cases with little patient compliance or time. By preference or if patients demand a natural morphology, Venus Bulk Flow ONE can always be used with capping layer, too. Using Venus Diamond or Venus Pearl on top might be advisable in big cavities or cusp replacements.
2. Does Venus Bulk Flow ONE require an opaque blocker?
In case of severe discolourations, the tooth-coloured opaque shade Venus Diamond Flow OM (Opaque Medium) can be used. Alternatively, the white-opaque Venus Diamond Flow Baselin-er can be used at the bottom of the cavity. This allows the coverage of discolourations and prevents the unnecessary removal of healthy tooth substance in case of a re-entry.
3. What are the differences between the usage of Venus Bulk Flow ONE and Venus Dia-mond/ Venus Pearl ONE?
Venus Bulk Flow ONE is a flowable bulk-filling composite with curing depths of up to 4mm whereas the high-viscous composites Venus Diamond and Venus Pearl in ONE Shade are ap-plied in incremental layering techniques in 2mm. The two different viscosities and application techniques imply different benefits complementing each-other in everyday posterior restora-tions.
4. Is Venus Bulk Flow ONE radiopaque?
Yes, Venus Bulk Flow ONE fillings are easily recognized on X-rays which supports a reliable diagnosis. Its radiopacity with app. 300%-Al is much higher than the radiopacity of dentine (100Al%) and enamel (200Al%).
5. Can Venus Bulk Flow ONE be used in the anterior region?
Venus Bulk Flow ONE is indicated for class III and class V restorations. The Adaptive Light Matching ensures an optimised colour adaptation in ONE shade. Customers have especially made good experience in terms of shade match if the class III restoration has a small labial part or an intact labial wall.
6. How is the ONE Shade working?
The ONE shade has been optimised to deliver the perfect balance of chroma and translucency that allows the restoration to become virtually invisible. Therefore, the ONE shade can be used with confidence in any Class I and Class II restoration. And this colour adaptation is what we call Adaptive Light Matching.
7. Can Venus Bulk Flow ONE be used in class IV cavities?
Independent from its usability, Venus Bulk Flow ONE is not indicated for class IV cavities.
8. What is the flexural strength in comparison to high-viscous composites?
Venus Bulk Flow ONE complies with ISO4049 and is released for posterior restorations includ-ing occlusal surfaces. Its flexural strength of 120MPa is on a level or even superior than lead-ing high-viscous composites which ensures a reliable resistance against mastication forces.
9. What is the wear resistance of Venus Bulk Flow ONE?
Venus Bulk Flow ONE has shown comparable wear rates to other composites indicated for the restoration of occlusal surfaces in the posterior region based on standard test methods.
10. How does Venus Bulk Flow ONE behave after teeth get bleached or are aging?
Venus Bulk Flow ONE does not bleach or age in colour itself. However, its Light Adaptive Matching ensures a colour match to any dentition which still applies to a certain extend to teeth getting bleached or that are aging. Kulzer however recommends whitening procedure to be completed a minimum of 14 days prior to placing the composite restoration. This is to en-sure an ideal fit in colour and proper curing of the dental adhesive.
11. Is Venus Bulk Flow ONE based on the traditional monomers like BisGMA, TEGDMA or HEMA?
Venus Bulk Flow ONE is based on established multifunctional methacrylate monomers (UD-MA, EBADMA).
12. Is Venus Bulk Flow ONE compatible with other composites and bonding agents?
Venus Bulk Flow ONE can be combined with all commercially available (meth)acrylate-based composites and bondings. We recommend the use of the universal nano-hybrid composite Venus Diamond or Venus Pearl as well as the bonding agents iBOND Universal or iBOND To-tal Etch.
13. What is the filler content?
Venus Bulk Flow ONE contains approximately 65 % by weight, or 41 % by volume inorganic fillers such as Ba-AI-F silicate glass, YbF3 and SiO2. The filler particle size is between 0.02 μm and 5 μm.
14. Does Venus Bulk Flow ONE release fluoride?
The glass fillers, used in the composite compound, contain fluoride. The glass structure bonds the fluoride ionicly and in this form, it is less soluble compared to sodium fluoride. This is why we can state that Venus Bulk Flow ONE releases some fluoride traces but beyond any clinical or caries protective relevance.
15. Can Venus Bulk Flow ONE be used for cementing veneers?
Independent from its usability, Venus Bulk Flow ONE is not indicated for cementing veneers.
16. Can brackets also be bonded with Venus Bulk Flow ONE?
Independent from its usability, Venus Bulk Flow ONE is not indicated for bonding of brackets.
