Aura a simple, easy,
beautiful SMILE
the logical, innovative restorative system designed to save time, every time • Based on the natural make-up and colors of enamel and dentin. • Simple layering technique to reproduce the natural colors of teeth. • High polishability and sculptability. • Designed to simplify shade matching for busy clinicians. How tooth composition determines tooth colour. • Since the colour of the tooth is determined by the dentine, not the enamel, the dentin shade plays a major role in determining the overall tooth colour. • The enamel is relatively translucent but requires high polishability.
Dentin is 95% of the tooth color1 • Single opacity • Hue saturation • Fluorescence Enamel is 5% of the tooth color1 • Translucency • Low hue • Opalescence ![](http://www.sdi.com.au/images/stories/products/aura_en/aura2_en.jpg)
Aura – how a linear scale provides an easy approach to tooth color selection.

Aura is the result of five years collaboration with international materials and tooth restoration experts. • Nearly all dentin has a similar “Hue”, falling in the red-brown-yellow range. • Aura focuses on where tooth colors vary, the “Chroma.” • Chroma is how strong or weak a color (hue) is, measured in % saturation. This linear and scientific arrangement brings predictability and simplicity to customising shades. ![](http://www.sdi.com.au/images/stories/products/aura_en/aura4_en.jpg)
| Aura – an easy approach to identifying and matching tooth color. Since the overall color of the tooth is determined by the dentin, not the enamel, choosing the dentin shade should be the first priority. Step 1 Select the dentin shade where there is exposed dentin or where the cervical area of the tooth is the thinnest.

Choose the enamel shade by observing the patient: E1 Young or bleached teeth E2 Adult teeth E3 Senior teeth Minimal volumetric shrinkage for maximal dimensional stability. Aura combines a new low-shrinkage resin composition with a new Ultra High Density (UHD) filler. ![](http://www.sdi.com.au/images/stories/products/aura_en/aura7_en.jpg)
High marks for Aura’s high flexural strength Aura’s superior flexural strength means it is able to withstand forces transmitted in the mouth. ![](http://www.sdi.com.au/images/stories/products/aura_en/aura8_en.jpg) Aura’s impressive compressive strength The unique morphology of the UHD filler provides an extremely high strength interface that can withstand high compressive forces.

Bulk fill • For quick posterior restorations where overlaying enamel is not necessary. • Designed to achieve high depth of cure and strength. Multipurpose use Also available in 4 multipurpose chroma shades MC2, MC3, MC4 and MC5. These are ideal for non-layering aesthetic and bulk filling requirements. 1 Chu S.J, Devigus A, Paravina R.D, Mieleszko A.
