Does this instrument measure translucency, why or why not? ShadeVision “sees” the tooth just as you do. Translucency is plainly visible in the images that are acquired. We do not currently assign a numeric value on translucency.
Does the user hit their target the first time, or are there some corrections that need to be made? The instrument’s unique viewing system insures that the tooth is properly targeted for measuring. The image that is captured is an accurate and detailed recreation of the tooth. The instrument's firmware incorporates a patented glare enhancement to help insure proper targeting.
Does the product meet regulatory requirements? The ShadeVision instrument has been classified as a Class I exempt device. The disposable tip will meet sanitary requirements. X-Rite is registered as a medical device manufacturer with the FDA and Health Canada. A 510K application or pre market notification was not required for ShadeVision because of it's classification. In Europe ShadeVision will be registered as a Class 1 device thus meeting their medical device directive.
What is the accuracy? Each tooth image that is captured by the ShadeVision System contains 22,000 individual measurements of hue, value, and chroma. With this information, the software can provide as much detailed and accurate information as required by the dentist and the laboratory.
How many teeth can the ShadeVision system measure? The instrument is designed to capture at least eight individual, highly detailed images of the patient’s teeth. These images are then rapidly uploaded into the computer via the docking station and the instrument is ready for more measurements.
What is the difference between the spectrophotometer used in the SpectroShade system and the technology used in X-Rite’s system? Our company is the world’s largest producer of spectrophotometers, densitometers, and colorimeters. We have considerable experience in understanding which measurement technology is most appropriate for an application. We have selected the best technology for tooth shade determination. Colorimeters see color like a perfectly functioning human eye. Our technology allows us to make accurate measurements in roughly one fifth the time of our competitors and at less than half the price! Our data can quickly be e-mailed, saved to file, or printed.
Being so small is it as accurate as your competitor's larger system? X-Rite has a proven history of developing products that offer capabilities equal to or better than larger more cumbersome technologies. We have applied that expertise to our development of the ShadeVision System.
Why is the probe so big? To maximize accurate image and color measurement, the instrument was designed to project collimated light through the probe with a viewing area of 5/8inch x 3/4 inch.
