Composite Shade Selection: A Repeatable Workflow | ATBIO

2026-10-14

Composite shade selection works best as a repeatable observation process. When the initial match and the finished restoration differ, review when and how the shade was chosen before concluding that the shade label was wrong.

Composite Shade Selection: A Repeatable Workflow(Image1)

1. Record shade before isolation changes the view

Tooth hydration affects apparent color. An in vivo investigation of dehydration documented color changes during drying. It does not provide one universal recovery interval for every patient or procedure. Select and record the starting shade before prolonged isolation, consistent with the material instructions, and avoid repeatedly drying the tooth simply to improve visibility during shade comparison. Source 1.

A randomized trial found that dehydration lightened teeth and that baseline shade had not returned within 30 minutes of rehydration under its study conditions. Burki et al., 2013

For training, keep the initial shade record before isolation. The study does not establish a universal rehydration waiting time.

Use a consistent viewing environment. Strongly colored surroundings and inconsistent illumination make repeat assessments harder to interpret. A photograph is useful documentation, but camera exposure and white balance can change its appearance; it should not silently replace the clinical observation.

2. Keep a short shade record

Record field	Why it helps
Tooth and restoration area	Cervical, body and incisal regions may need different consideration
Hydration and isolation stage	Explains a changing appearance during treatment
Light and photograph settings	Makes later comparisons more reproducible
Material, shade and opacity	Prevents treating a shade name as a complete specification
Cured sample and final finish	Separates shade selection from paste appearance

3. Use the actual restorative material when appropriate

A shade tab is a starting reference. Where the manufacturer's instructions and clinical situation allow, an appropriately made cured material sample can help assess the selected product. Follow the applicable curing and removal procedure; do not leave an informal trial attached or create an unsupported bonding step.

Evaluate shade and opacity separately. A nominally correct shade may still show too much background or insufficient translucency. Finish the evaluation surface consistently because different surface textures make a visual comparison less reliable.

For purchasing, maintain a product-specific shade list rather than assuming that every A2 from every range is interchangeable. Ask ATBIO for the available Z250, Universal Aesthetic or NOVA shades and their current documentation. Include the existing material you want to compare and the clinical application.

4. Build a shade demonstration that distributors can repeat

A shade name identifies a position within a manufacturer's system; the finished appearance also depends on opacity, thickness and the surface being viewed. For a useful demonstration kit, label each cured specimen with the product, shade, thickness and preparation date. Use the same background and finishing method across comparable specimens. Keep the natural tooth observation and the model demonstration as separate records: a model helps explain a material, while clinical selection concerns the individual tooth.

The NANOFIL restorative-composite V2601 instructions place shade selection before isolation. This gives a distributor's training card a concrete sequence: initial shade record, material selection, isolation, restoration and final assessment. It also gives the sales team a better answer than recommending a different shade whenever a photograph looks lighter.

5. A practical record for customer training

Entry	Example of a completed training record
Purpose	Demonstrate the customer's routine anterior shade selection
Specimen identity	Product and A2 label; actual thickness recorded beside the specimen
Viewing conditions	Same lamp, background and camera settings for every comparison
Decision	Include the requested shade and opacity in the sample assortment

This is an illustrative record, not a reported clinical result. When requesting samples, specify the shade codes currently purchased and the applications driving demand. ATBIO can then address the relevant assortment, rather than treating a visual question as a request for every available shade.

Frequently asked questions

When should I select the starting shade?

Before prolonged isolation or drying changes the tooth appearance, following the clinical workflow and instructions.

Is one photograph enough to approve a shade?

No. It records a view under particular settings and should be interpreted alongside clinical observations.

Does the same shade name guarantee the same result?

No. Record the manufacturer, product and opacity as well as the shade designation.

What should a distributor request for a shade evaluation?

The current shade list, exact sample identifiers and a consistent evaluation record for participating clinicians.
