ENA HRi® nano-hybrid composite produces incredibly natural looking composite restorations. ENA HRi® enamel and dentine shades feature a list of unique properties that allow clinicians to match a natural tooth’s optical properties to produce incredibly life-like restorations with invisible margins.
 | ENA HRi® was developed in Italy by Micerium S.p.A. based on the ideas, research and principles of Dr. Lorenzo Vanini. |
The key to ENA HRi esthetics is an exclusive patented enamel composite material. ENA HRi enamel composite refracts light like human enamel. This development creates invisible margins without the need to compensate by increasing bevels and increasing the thickness of dentin composite.
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].
| UE1 | UE2 | UE3 |
| Low value enamel | Medium value enamel | High value enamel |
| Older patients | Middle aged patients | Younger patients |
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:
| Composite | Refractive Index |
NATURAL ENAMEL | 1.6200 |
ENA HRi (Micerium) | 1.6200 |
| Clearfill Majesty (Kuraray) | 1.5320 |
| Filtek Supreme (3M) | 1.5270 |
| Point 4 (Kerr) | 1.5230 |
| Esthet-X (Dentsply) | 1.5210 |
| Venus (Kulzer) | 1.5210 |
| Tetric Ceram (Ivoclar) | 1.5195 |
| Kalore (GC) | 1.5132 |
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
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.
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 offers additional shades to reproduce the characterization of an individual’s nature dentition.
These shades include:
INTENSIVE
Intensive Milky, Intensive White Spot
OPALESCENT
Opalescent Amber, Opalescent Blue

Step 1Class IV lesions in a young patient; on the lateral incisor the lesion is very deep, close to the exposed pulp. The elements show positive test to vitality. | Step 2Cavities: on vestibular side a chamfer has been prepared on the enamel thickness, while on the interproximal and palatal wall a 90° preparation has been made; the exposed dentine has not been touched. | Step 3The silicone index, obtained by the diagnostic wax up and properly cut, is tried after isolation of the field. |
 |  |  |
Step 4After the adhesive phase, to create the palatal walls, a thin enamel layer is applied on the silicon index. The enamel HRi UE2 is applied on the cavity margin with a dry brush, then it is cured and the stent removed. | Step 5With an acetate matrix, the interproximal walls are restored with the same enamel body. | Step 6Dentine body build up with dentine HRi UD4 and UD3. |

Step 7Vestibular enamel created with same HRi UE2 shade that is used also to fill the space between mamelons to create the opalescent. | Step 8Case finished. | Step 9Case finished. Palatal view. |
