ENA HRi®

Just like NATURE… HRi enamel shades act like human enamel

The HRi system contains only 3 achromatic enamel shades, and these are related to the patient’s age group. Young enamel is very bright [high value = UE3]. As patients approach middle age, this value decreases [medium value = UE2]. The process continues as patients reach their senior years [low value = UE1].

A thicker HRi enamel increases the opalescent effect

HRi enamel shades allow clinicians to obtain invisible margins, without compensatios (increasing bevels and increasing the thickness of dentin composite). This is obtained through the exclusive patented refraction index of HRi enamel shades, with is identical to human enamel:

ENA HRi is the only composite material that has the same refractive index as natural enamel.

Why traditional techniques don’t work

If you are frustrated with spending precious time to produce a high level esthetic composite restoration, only to be disappointed in the result, it’s not your fault. With traditional layering techniques, it’s a hit-or-miss process.

Popular enamel composites produce a graying effect as they are applied in thicker layers, because their refraction index is not tuned to human enamel. The only way they achieve results is through a complicated and unpredictable layering technique. Even if successful under certain lighting conditions, these restorations are subject to metameric failure.

Traditional restorations leave visible margins

HRi Technique – Invisible margins

Invisible margins, reproducing with HRi the same thickness of the natural enamel. *Measurements refractive indices from the University of Fraunhofer Institute Dresden, on enamel shells natural and universal enamel HRi.

Just like NATURE… HRi dentin shades act like human dentin

The HRi system dentin shades make up the dentin mass that transmit their hue and chroma through the enamel mass. The shades are highly fluorescent and are designed to work with the HRi enamel shades for optimal results.

HRi has a fluorescent dentin

Just like NATURE… HRi additional shades complete the characterization

Physical properties

Abrasion resistance

Rel. wear factor [ 200 000 cycles ]

HRi shows superior resistance to wear – it is designed for both simple and complex direct and indirect restorations.
