The VITA Classical Shade Guide is an essential tool for dental professionals in accurately determining tooth shades for restorative procedures. This comprehensive shade guide comprises sixteen distinct color categories, each represented by a range of shades denoted by letters and numbers, from A1 to D4. These categories encompass a spectrum of natural tooth colors, including reddish-brownish, reddish-yellowish, grayish, and reddish-grayish tones. To ensure precise color matching, the guide should be held at an angle of approximately 25-30 cm from the patient's tooth, with the arm comfortably bent.
The guide offers valuable tips for optimal shade determination. Performing the assessment prior to tooth preparation is advised, as dehydration during preparation can alter the perceived shade. Natural daylight or standardized daylight lamps (5500K - 6500K) are recommended for accurate assessments, avoiding typical indoor lighting conditions. Creating a neutral-colored environment is crucial, with patients removing any influencing lipstick or cosmetics, and covering brightly colored clothing with a gray cape.
Additionally, the VITA Classical Shade Guide emphasizes the importance of promptly disinfecting the guide after each use, ensuring a hygienic and safe application. The guide's acrylic components are made of a durable, temperature-resistant material that can be surface disinfected, further enhancing its longevity and usability. For added versatility, the guide can be autoclaved up to 132 °C/270 °F, providing a sterilization option.
Direction to use
Preparation: Before using the Vita Classical Shade Guide, familiarize yourself with the shade categories and color ranges provided.
Positioning: Hold the shade guide with your arm bent at approximately 25-30 cm (about 10-12 inches) from the patient's tooth.
Assessment: Compare the natural tooth color with the shade samples in groups A – D. Move swiftly to make a selection.
Pre-Preparation Assessment: It is recommended to determine the tooth shade before any preparation, as the tooth may appear lighter due to dehydration after preparation.
Lighting Conditions: Ensure that the tooth shade determination is conducted under natural daylight or standardized daylight lamps (5500K - 6500K), not under typical indoor lighting.
Environmental Considerations: Maintain a neutral-colored environment. Remove any influencing lipstick or cosmetics. Cover brightly colored clothing with a gray cape.
Proximity: Position the shade sample tooth as close as possible to the patient's tooth for accurate comparison.
Focus on Middle Area: Consider only the middle area of the shade sample tooth for selecting the shade.
Prompt Decision Making: Make your choice swiftly and accept your initial decision, as the eyes begin to tire after approximately 5-7 seconds.
Disinfection: After each use, disinfect the Vita Classical Shade Guide using mild surface disinfectants or disinfectant wipes. Follow the manufacturer's instructions for use.
Material Care: The acrylic parts of the shade guide are made of high-quality, temperature-resistant, and easy-to-clean material. They can be surface disinfected.
