Koungsun E220 Digital Dental Shade Guide & Shade Matching Device

Make tooth shade selection faster and more consistent with the Koungsun E220 digital dental shade guide. This handheld dental spectrophotometer measures natural tooth colour and displays the closest matches from the VITA Classical A1–D4 and VITA 3D-MASTER shade systems in approximately one second.

Designed for dentists, restorative teams and dental laboratories, the E220 helps reduce subjectivity during tooth shade matching and makes it easier to communicate a patient's natural tooth shade for crowns, veneers, bridges, composites and other esthetic restorations.

It is a digital alternative to the traditional VITA shade guide, replacing visual shade-tab comparison with a measured result.

Digital dental shade matching in approximately one second

Place the detection head in full contact with the natural tooth and press the measurement button. The Koungsun E220 analyzes the tooth colour and displays results for both supported VITA shade systems. Its colour-coded comparison display helps the clinician interpret how closely the measured tooth matches the displayed shade.

Made for natural tooth shade measurement

The E220 is intended to measure natural tooth colour. It does not directly measure crowns, veneers, dentures, dental models, restorative materials or shade tabs. Instead, the clinician measures the patient's natural tooth shade and uses that information to help select and communicate the desired shade for restorative treatment.

Supported dental shade systems

• VITA Classical A1–D4
• VITA 3D-MASTER

These results help create a clear, repeatable reference for restorative planning and dentist-to-laboratory communication. VITA and VITA 3D-MASTER are trademarks of their respective owner; Koungsun is not affiliated with VITA Zahnfabrik.

Recommended tooth shade matching workflow

1. Clean visible debris from the natural tooth surface.
2. Remove the silicone protective cover from the detection head.
3. Position the patient with the head supported and identify the area with the thickest dentin layer.
4. Place the detection head in full contact with the middle or cervical area of the tooth.
5. Press the measurement button and maintain contact until the signal sounds.
6. Review the VITA Classical and VITA 3D-MASTER results shown on the display.

Clinical conditions and restorative workflows vary. Use professional judgment and your laboratory's shade-communication protocol when selecting the final restorative shade.
