2 TRIOS Shade Measurement Shade measurements with TRIOS® Good practices for getting accurate shade measurements using TRIOS
3 Requirements for Shade measurements TRIOS Shade MeasurementRequirements for Shade measurementsShade compatible scanner. *TRIOS Color Cart, Color Pod, Color CIKTRIOS software ( or later)Color calibration kit. *NOTE* See mail ‘TRIOS Color Calibration Kit now available for shipping’ of for details
4 Color Calibration Kit Don’t touch by hand TRIOS Shade MeasurementColor Calibration KitColor calibration kit:Left: Color calibration targetMiddle: Tip-adapterRight: CombinedDon’t touch by handClean with filtered air at low pressureStore in the protective sleeve and out of direct sunlight
5 Unclean Mirror of Tip Unclean mirror of tip TRIOS Shade MeasurementUnclean Mirror of TipUnclean mirror of tipSome autoclaves leave stains on the mirror. Usually doesn’t affect the scanning, but the strict tolerances of the color calibration may cause the color calibration to fail.Fix: Clean the mirror with a soft cloth and run the color calibration again. If this is not successful, try with a new tip, which has not been autoclaved.Mirror with depositsClean mirrorNote: It is easy to inspect how clean the mirror is by attaching it to the scanner and then starting the scanner. If the mirror is clean, you will see no haze or dirt on the mirror.
6 Unclean Front Glass Front glass of inner black tube of scanner TRIOS Shade MeasurementUnclean Front GlassFront glass of inner black tube of scannerOver time, a thin film of residue will deposit on the front glass of the inner back tube of the scanner. This film is not visible to the naked eye, so it is not possible to detect it.Fix: Wipe the front glass with a dry optical cloth.
7 Unclean Calibration Target TRIOS Shade MeasurementUnclean Calibration TargetAreas that must be free from dust, dirt etc.The color calibration target may be unclean. Inspect both sides for dust, dirt etc.You should never under any circumstance touch the optical components of the color calibration target. Clean only with filtered air at low pressure
8 TRIOS Shade Measurement External Lights?External light may affect the shade measurement! It is important to turn off all intense lights prior to scanning. Turn off the dental lamp, as the intensity is very high. Normal room lighting is not a problem for the TRIOS®.
9 TRIOS Shade Measurement First Scan StrategyScan preparation first, and then lock the margin lineStep 4:Select the shade icon to the right on the TRIOS® monitor. A blue overlay will appear where the scan quality is not sufficient for performing shade measurements. Scan the tooth you want to use for shade measurement until blue overlay clears out. (please refer to section “Adding shades to the scan”)Step 1:Remove the retraction cord and scan the preparation immediatelyStep 2:Lock the margin, using the lock tool.(paint the area around the margin)Step 5:Place shade measurement circleYou find the lock tool under the tool bar button ‘Tools’Step3:Scan the rest of the arch
10 Second Scan Strategy Scan margin as the last thing you scan TRIOS Shade MeasurementSecond Scan StrategyScan margin as the last thing you scanStep 4:Trim margin awayStep 1:Scan arch with cord in placeStep 2:Select the shade icon to the right on the TRIOS® monitor. A blue overlay will appear where the scan quality is not sufficient for performing shade measurements. Scan the tooth you want to use for shade measurement until blue overlay clears out. (please refer to section “Adding shades to the scan”)Step 5:Remove cord and scan margin immediatelyStep 3:Place shade measurement circle
11 Third Scan Strategy Use a pre-preparation scan TRIOS Shade Measurement Step 1:Add pre-preparation scan on order formStep 4:Place shade measurement circle on the pre-preparation scanStep 2:Go to the pre-preparation scan page and scan the archStep 5:Go to preparation scan page and scan the preparation onlyStep 3:Select the shade icon to the right on the TRIOS® monitor. A blue overlay will appear where the scan quality is not sufficient for performing shade measurements. Scan the tooth you want to use for shade measurement until blue overlay clears out. (please refer to section “Adding shades to the scan”)
12 TRIOS Shade Measurement Adding Shades to a Scan3 easy steps to obtain a scan quality that is sufficient for adding shade measurements:Select the tooth to measure shadeIf the center of this tooth has blue overlay you will need to scan some more in this region until the blue color clears up: This is done by adding more sub scans and from different angles. A fast way to do this is to move the scanner 90 degrees slowly from occlusal to buccal or vice versa. See image belowNote that you do not need to remove the blue overlay completely, just enough to place shade measurement circle(s) on the center of the one tooth selected for shade measurementExample of blue overlay (Shade scan quality)
13 Defining the Shade measured by TRIOS TRIOS Shade MeasurementDefining the Shade measured by TRIOSThe shade value guides have a fixed number of shades.In some cases there will not be a shade that matches the captured color perfectly.The TRIOS® always gives you the best matching shade.The shade reported by TRIOS® always corresponds to the circled area in the figure

15 Warning indication if rule is violated TRIOS Shade MeasurementPlacing the shade measurement circlesWhere to place the shade measurement circle?Warning indication if rule is violatedIn areas where the shade inside the measurement circle is uniformIn areas with sufficient scan quality.When you have turned on the scan shade-quality overlay, the areas with sufficient quality are the areas with no blue overlayIn areas with regular tooth color.Areas with irregular tooth colors are gingiva, heavily discolored stumps etc.Note: This also implies that you should not place the measurement circle atInterproximal areas. These are usually colored blue, indicating insufficient scan quality for shade measurement)Translucent areas, typically close to incisal edge
16 TRIOS Shade Measurement Adding HD PhotosThe shade of the tooth is provided by the shade measurement functionality of the TRIOS®.In most cases, a photo that show aesthetic details in the teeth (e.g. internal cracks, mineralizations, etc.) will accompany the shade information. The source of this photo may be an external SLR camera and the photo is transferred to the lab by means of e.g. .In TRIOS® you may take one or more HD photos of the teeth. These HD photos are directly embedded in the order and consequently no separate ing is required.Each HD photo is put on the actual 3D model, so that you may inspect the HD photo on the real tooth geometry.Example of HD photo in combination with shade measurement circles
17 When to Color Calibrate? 3ShapeWhen to Color Calibrate?Color calibrate the scanner before each scan for optimal color quality if you intend to use Shade Measurement.The mirror in the tip is almost never 100% clean, small variances could have an impact on the Shade Measurement.Color calibration has a weekly reminder. Shade Measurement will be disabled if the scanner has not been color calibrated for 30 days.
