Heraeus Kulzer has extended its successful range of Charisma composites with the introduction of Charisma Opal.

According to Heraeus Kulzer, the innovative submicron-hybrid composite enables dentists to create highly aesthetic, invisible restorations in an even simpler, more usable manner. Its intrinsic colour characteristics mimic the colour and lustre of the natural tooth substance. A compact shade system and a 2-Layer shade guide from original material allow for easy and accurate shade matching.

The new light-curing submicron-hybrid composite from the Charisma brand is based on Heraeus Kulzer’s years of experience in the ongoing development of composite materials. The innovative filler technology of Charisma Opal is based on X-ray opaque Microglass and highly dispersive silicon dioxide, providing the composite with a pronounced chameleon effect and high radio-opacity.

With the intrinsic colour effects, Charisma Opal reproduces the natural opalescence, fluorescence and translucent effects of the patient's surrounding tooth substance. Exhibiting all dimensions of colour the new composite really creates lifelike restorations.

Due to its compact, comprehensible shade system Charisma Opal is time-saving and easy to use. With only 14 shades in three different opacities it covers all indications in aesthetic restorations, from shape and shade corrections over splinting teeth to restorations of primary teeth.

A 2-Layer shade guide made of original material makes selecting the most appropriate shade easy. The guide consists of a base layer of opaque dentin composite with a layer of universal composite over the surface.

As a result, it shows the exact colour effect of the final restoration. Thus, the 2-Layer shade guide minimises the risk of wrong shade matching, which is the most common reason to renew restorations.

Research groups worldwide have verified the benefits of Charisma Opal, according to Heraeus Kulzer. In a study on the polishability of composites conducted by the Fraunhofer Institute Freiburg, Germany, the new submicron-hybrid composite showed the lowest average surface roughness of all tested materials what leads to high gloss polishing as well as low plaque accumulation.

This and further studies have proven that the new formula of Charisma Opal combines great aesthetics with equilibrated physical properties, says Heraeus Kulzer. www.heraeus-kulzer.com
