Vita Classical Shade Guide
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.
- Comprehensive Shade Range: Offers a wide spectrum of shades (A1, A2, A3, A3.5, A4, B1, B2, B3, B4, C1, C2, C3, C4, D2, D3, D4) for precise color matching.
- Natural Tooth Color Representation: Categorizes shades into reddish-brownish, reddish-yellowish, grayish, and reddish-grayish tones, mirroring natural tooth colors.
- Accurate Assessment: Provides guidance on proper positioning (25-30 cm distance with bent arm) for accurate shade determination.
- Pre-Preparation Evaluation: Recommends assessing tooth shade before any preparation to account for potential dehydration-induced color change.
- Optimal Lighting Conditions: Suggests using natural or standardized daylight lamps (5500K - 6500K) for accurate color evaluation.
- Environmental Considerations: Encourages a neutral-colored environment, devoid of influencing cosmetics or bright-colored clothing for precise results.
- Hygienic Application: Can be easily disinfected after each use with mild surface disinfectants or wipes, ensuring a clean and safe application.
