Description of the shades:

The T-Blue shade was developed with a subtle bluish quality just like the enamel of the incisal third of young teeth. The T-Orange shade contributes to the orange characterization of the tip of the mamelons. The T-Yellow shade presents high translucence, without pigments, giving depth to the restoration, and can be used as a last layer without changing the resin shade of other layers of the restoration. The T-neutral shade, in turn, resembles the incisal shade, presents average translucency and is used to reproduce the least translucent incisal third.

The pastes for correction of the value were developed with different levels of white pigment to be used as the last layer and in accordance with the patient’s age: VH for the teeth of children and adolescents (whiter, more opaque), VM and VL for adult teeth and teeth of older people (less white, more translucent).

Extra-opaque shades:
The extra-opaque shades, Opaque White (OW), Opaque Pearl (OP), B0.5 and A0.5 are useful for masking darkened teeth. Fine layers of these resins can mask a dark background. Typical cases of class III restorations are solved by using extra opaque resins that block the passage of light through the tooth. The OW shades is presented with a high content of white pigment, the OP shades has equal opacity, but resembles the VITAPAN® Classical scale A2; B0.5 and A0.5 are lighter shades than B1 and A1, respectively, but with very high opacity. These two shades can also be used to reconstruct deciduous teeth, due to the high level of opacity in these tissues.

Bleach Shades:
The Bleach shades were developed especially for reconstructing teeth whitened whose chroma is below the VITAPAN® Classical scale shades, that is, lighter than the shades A1 and B1. Opallis contains three shades to reproduce enamel, divided into E-Bleach H, E-Bleach M, and E-Bleach L. The terms H, M and L define the chroma order, wherein H refers to the lighter shade (high) and L the shade with the greatest chroma (low). To reproduce the dentin, the shade OF Bleach was developed with opacity similar to dentin shades. As such, the combination of these optical properties makes Opallis resemble the tooth structure, allowing reproduction naturally and imperceptibly. The distribution of particle size permits adequate filling of the resin, contributing to its high mechanical strength and wear characteristics necessary for restorations in posterior teeth, and the small average particle size provides ease of polishing, generating a restoration with a smooth surface and high brightness.

Step by Step

Shade selection

For the shade selection, carry out prophylaxis. The teeth should be clean, hydrated and without isolation, since dehydration can change the shade.

Methods for choosing the shade

• This can be conducted with the commonly used VITAPAN® Classical scale.
• A small portion of resin composite may be placed on the vestibular surface of the tooth to be restored (without etching and application of the adhesive system), light cured for 30 seconds, humidified with the patient’s saliva and observed. This stage may be conducted to confirm the shade of the resin composite.
• For more challenging cases we recommend that the professional first produces a chromatic map of the tooth. The chromatic map includes the most detailed information about the individual characteristics of the teeth.


Step 1

As the enamel and dentin have different opacities, to restore lost tooth structure correctly it is necessary to have translucent enamel and dentin resins to work the incisal and opaque area to make the sclerotic dentin opaque.

Step 2

Undertake the preparation for execution of direct adhesive restorations.

Step 3

Undertake acid etching (Condac 37 – FGM) initially in the enamel margins and then inside the cavity. The conditioning time is 15 seconds. Next, wash with plenty of water, remove all of the acid from the dental structure and dry the dentin without dehydrating it.

Step 4

Apply the adhesive system according to the manufacturer’s recommendations.

Step 5

Insertion and light curing of the resin composite:

• We recommend inserting and curing in increments. This technique allows more uniform curing. Use the curing times described in the Instruction for Use for layers of resin up to 1.5mm.
• Restore the cavity in accordance with the shade selected, applying thin layers of Opallis (maximum of 2mm) carefully adapting to the cavity.
• To enable better curing of the last resin layer, apply an insulating gel and light cure for 40 seconds.

Step 6

For finishing and polishing, Diamond Pro sandpaper disks and Diamond Flex felt disks can be used with the aid of Diamond ACI and ACII and Diamond Excel polishing pastes.


Checking occlusion is an extremely important factor. Restorations in supraocclusion cause major stress on the tooth and restoration that can lead to pain. Do not leave them in infraocclusion.


Can Opallis be used in restorations of anterior and posterior teeth?

Yes, it can be used in both anterior and posterior teeth. All micro hybrid resins have this inherent characteristic, because of the size and distribution of the particles, good resistance to abrasion (desirable property in class I and class II restorations) and resistance to fracture (class IV, for example). Laboratory studies on Opallis resin show very good results when compared to other resins of the same classification. Such studies can be proven clinically in follow-ups after 12, 18 and 24 months of Opallis, which are done at many universities nationwide. Great advantages of Opallis resin, especially in the anterior teeth, are the aesthetic features present in some shades, such as in transparent and opaque ones. This provides endless combinations and effects to be reproduced with this material in the office.

Why does Opallis have 4 levels of translucency?

As the enamel and dentin have different opacities, to restore lost tooth structure correctly it is necessary to have translucent enamel and dentin resins to work the incisal and opaque area to make the sclerotic dentin opaque.

What is fluorescence?

This is the tooth’s capacity to absorb ultraviolet radiation (e.g. black light) and issue this radiation in the visible light range, giving it a bluish appearance.

Why is it important for the resin to have fluorescence?

Because in order to restore part of the lost tooth, it is necessary to reproduce all of the properties of the natural tooth. Nonfluorescent resins are detected as dark areas when exposed to ultraviolet light.

There are various levels of fluorescence in resin composites. How can I identify if a resin has fluorescence compatible with the tooth structure?

Resin manufacturers conduct tests on their enamel masses, dentin and effects, comparing them with pre-established standards for all resin masses with natural dentin and enamel. This ensures fluorescence at the right amount for use with resin composite restorations. Ultraviolet light is used clinically and in the laboratory for this distinction. As the acquisition of such equipment it is often costly for the clinician, a good solution is to resort to the Instructions for Use, materials with a good origin and scientific articles. Check the Technical Profile of the resin to be used, seek out quality literature and understand what fluorescence is. FGM provides all of the equipment for certification of its resin composite, such as a spectrophotometer, rheometer and ultraviolet light, ensuring not only adequate fluorescence, but also all the physical and mechanical properties that a micro hybrid composite requires.

What is the importance of opalescence in a composite resin?

Opalescence is a property of the enamel, observed mainly in the incisal and proximal edges, related to the capacity to selectively transmit the long-wave spectrum, giving the enamel the appearance of an orange hue. At the same time, it reflects short wavelengths, which give the enamel a bluish coloration. This is an important property because depending on whether the incident light is transmitted or reflected, the restorative material has different shades under such lighting, simulating what happens in a natural tooth.

What is the influence of the power of the curing light for activation of resin composites?

For best results, we suggest a minimum power of 450 mW/cm² for proper curing, reducing shade changes, percolation and infiltration. To guarantee the quality of the restorations, it is necessary to periodically assess the power density of the light-curing unit. Maintenance of the lamp should be undertaken whenever necessary.

Microparticle resins are used on the surface to reproduce the enamel and improve polishing quality. Can we achieve good polishing with the Opallis composite (micro hybrid)?

In a recent study (Ardu & Krejci, Quintessence Int, 2006), the result of the veneering technique with microparticle resins was evaluated after 20 years of clinical performance. The authors point out that the microparticle resins do not have sufficient fracture resistance to be used in large volumes and conclude that “the use of appropriate techniques and materials allows optimal aesthetic results for restoration of small and medium anterior defects with direct composites”. The particle size distribution allows for adequate filling of the resin, contributing to its high mechanical strength and wear characteristics necessary for restorations in posterior teeth. The reduced average particle size provides ease of polishing, creating a restoration with a smooth surface and high shine, which dispenses with the use of a microparticle resin as a final layer. It is worth noting that using a resin other that Opallis in the last layer may change the final fluorescence of the restoration. For example, a microparticle resin without fluorescence will mask the fluorescence of the Opallis layers, presenting an average particle size of 0.5µm. The micro hybrid Opallis composite resin has adequate distribution of particles (40nm – 3µm).

How can I mask class III restorations with Opallis?

The visible line between the tooth structure and resin composite is very common in situations where we work with small volumes of composite. This occurs due to insufficient masking of the enamel/resin interface. This unpleasant effect can be corrected with the application of dyes (a difficult additional clinical step) or a small layer of the dentin shade of Opallis resin in most cases, or sometimes an opaque OP, OW, B0.5 A0.5 over approximately half of the enamel (beveled or not), making the opacity of such resin mask the effect as a preventive measure.

What are the indications for the extra-opaque resins (Opaque Pearl, Opaque White, A0.5 and B0.5)?

The Opaque Pearl and Opaque White resins are indicated for opacification of dark backgrounds (sclerotic dentin and stained dentin in pulpless teeth), both in anterior and posterior teeth. They can also be used as an effect resins to simulate whitish areas, hypoplastic spots and in some selected cases, Opaque Pearl and Opaque White can be used to build the opaque incisal halo. A0.5 and B0.5 are resins developed for use in pediatric dentistry, as they are more opaque, and include shades compatible with deciduous teeth. However, there is nothing preventing them from being used in bleached teeth, provided the prior selection of shades coincides with these shade options.

The greatest difficulty presented by professionals is the masking of darkened dentin. Few composites exhibit sufficient opacity to successfully mask the shade change. Does Opallis have resins for this purpose?

This procedure require resins with greater opacity even in small thicknesses, such as the Opallis Opaque White, Opaque Pearl, A0.5 and B0.5. The dark background is common in everyday clinical practice, because we often come across stained or darkened sclerotic dentin. Especially in type I and II cavities in posterior teeth and veneers in pulpless teeth, there commonly exists a need for opacification of darkened dentin. This procedure requires resins with greater opacity even in small thicknesses. The shade OW (Opaque White) gives us a “white” opacity, transforming dark background leaving it ready to receive “shade”, i.e. the dentin and enamel. The shade OP (Opaque Pearl) has an opacity with a subtle hint of yellow (“pearl”) and can be used for opacification or when creating effects such as hypoplastic white spots or incisal halo reconstructions. The shades A0.5 and B0.5 are a half tone lighter than A1 and B1, respectively.

What is the function of the shades A0.5 and B0.5? Can they be used in bleached teeth with chroma below the shade A1?

The “shade selection” procedure is used to determine which shades should be used in a restoration. If shades A0.5 and B0.5 of the Opallis resin are required after dental bleaching, they should be used. Despite being created with the main indication of being used in deciduous teeth with high opacity, there is nothing stopping them being used in permanent teeth.

What is the difference between the Opallis Bleach shades (L, M and H)? Is there is a variation in the yellow content?

The difference is that although all of them present lighter shades than the standard B1 from the VITAPAN® Classical scale there are small variations in chroma between these resins. Bleach H presents lower chroma (less yellow). Bleach L presents a higher chroma, thanks to the greater amount of yellow pigments. Bleach M is in the intermediate range, balancing the yellow levels.

How do I use the effect shades (T-Neutral, T-Yellow, T-Orange, T-Blue) in a restoration?

What the eyes don’t see, the hands are unable to perform. For a long time, transparent effects were hard to find on the market, and were almost exclusive for some materials. The “T” resins in question are more transparent than enamel resins, with higher translucency (66 to 79%). The shades aggregated in these Opallis transparent resins provide an ability to create effects such as those found in the incisal region of young teeth, bluish areas or even more transparent ones where light passes without being reflected. The choice between Neutral, Yellow, Orange and Blue is very personal and directly dependent on the case. Detailed observation of what you want to produce is the most important factor when selecting the “T” resin for the restoration. As a rule, they should be inserted between the spaces created in the dentin resin in the incisal region, opening space for the incisal border to be naturally compatible with that found in nature. The shade T-Yellow is very translucent and has no pigmentation. It can be used as the last layer to simulate the enamel. The use of this shade gives depth to the restoration, making it natural. The shade T-Neutral presents lower translucency than T-Yellow, but higher than the conventional enamel shades. It meets the majority of situations for incisal third and palatine restorations.
