1. Why is the possibility of composite fillings in 2 layers an advantage?
It is of advantage In order to fabricate aesthetic fillings. Particularly in the anterior area it is frequently necessary to fabricate the cavities using opaque dentin and translucent enamel shades similar to the structure of the tooth: dentin and enamel layer.
2. Basically, must Venus fillings be place in 2-layer system?
No! If aesthetic aspects are secondary because of the situation of the fillings to be placed such as in the area of the molars, for example, the layer technique can be omitted. In these cases the enamel shades are used.
3. What does Colour Adaptive Matrix mean?
This means the property of Venus shades that allows it to match the shade of the natural tooth. The refractory indices of the filler and the monomer system are optimized in Venus so that Venus restorations take on the shade tones of the surrounding tooth substance. When this is done and with correct selection of shade, the tooth and restoration become one.
4. What are the benefits of the Venus composite property described as “sculptability”?
After application of Venus the material remains unchanged in its shape and position; it does not spread under its own weight. Under loading, however, it assumes the desired contours satisfactorily and without high pressure so that it is as appropriate for placing fillings in the anterior as well as in the posterior area.
5. Why is the Venus shade guide special?
The shade guide consists of the Venus original material and not of acrylic, so that the colour fidelity between the shade taken and the restoration are identical. The opaque and enamel shades were used for layering the sample; this facilitates determination of shade in the patient.
6. What can be said about the clinical performance of Venus?
Venus composition is based on years of satisfactory clinical experience with Charisma. The ingredients are identical but the proportions of the individual components differ. Thus, using Venus is not an “experiment”; it has been available since 2002. 2-years results of clinical studies on Venus at the University of Loma Linda, USA, prove the excellent clinical viability and durability of Venus restorations (Source: J. Dunn, University of Loma Linda, USA, IADR 2007 New Orleans, Poster 1575).
7. What are the essential differences between Venus and Charisma?
Venus is more stable than Charisma and accordingly can be better modelled. The Venus product line has more shades and special shades and more shade tones, which are easier to combine in virtue of their corresponding nomenclature. The Venus Shade Guide has a double-layer construction and, in addition, also provides the shade combination of dentin and enamel shades, which makes it possible to obtain exact correspondence between shade selection and restoration.
8. For what are the HKG shades HKA2.5 and HKA5 created?
The HKA2.5 shade closes the gap between the most popular Vita shades, A2 and A3. There was a corresponding market demand for an intermediate shade.HKA5 is intended especially for use in treating cervical lesions in older patients. Previously, there was no corresponding reddish brown darker shade for this indication.
9. Is a composite system having a total of 27 shades contemporary?
A comprehensive system like Venus is required for fabricating highly aesthetic fillings. In this scenario, the complete Venus system is compact and provides a maximum of options.
10. Are there any differences in the curing times between the enamel and opaque shades?
Yes! The opaque and even some enamel shades (A4, B3, C3, C4, D3, HKA5) must be cured for 40 seconds. Because of their high shade density they absorb more light than the enamel shades. 20 seconds is adequate for setting of all other standard Vita shades.
11. Which HKG bonding systems are recommended for use with Venus?
All of them! In other words, iBOND Self Etch, GLUMA Comfort Bond + Desensitizer, GLUMA Comfort Bond and GLUMA Solid Bond can be processed with Venus.
- Direct restorations of class I-V cavities (according to G. V. Black)
- Direct composite veneers
- Shape corrections of teeth (ie. diastemas, congenital defects, etc.)
- Temporary splinting of teeth loosened by trauma or periodontal disease
- Indirect restorations (inlays, onlays)
- Restoration of primary teeth
- Core build-up
- Temporary repairs of porcelain, composite (in combination with an adequate repair-system)
13. What does “PLT” stands for?
"PLT" is the abbreviation of "preloaded tips“.
