A human being can distinguish between about 200 tones. When changing the intensity of a tone, about 500 different luminosities are produced. Finally, if you change the amount of white of a tone, you get about 20 more colors per tone. In total, man is able to distinguish between about 20 million colors!
Many Animals Distinguish Even More Colors Than Humans
It is impressive. However, the human being does not stand out for his perception of color. Unlike us, insects, almost all fish, reptiles, and birds, perceive ultraviolet light, which allows them to distinguish even more colors than humans.
Color Perception Is Often Subjective
An important point about color perception is that it is a sensation; it is not defined uniquely, so it varies from person to person. For example, a person with problems perceiving red and green interprets colors differently from a person who normally perceives red and green. It’s something like: “I see things you don’t see.”
Tone And Translucency Can Be Easily Measured
However, two important and measurable basic factors that experience has shown to have a significant influence on the aesthetic perception of a restoration from the patient’s point of view can be clearly identified:
- The color of the material
Translucency is a physical property and an important measure. Describe the transparency of a material. The intensity of this transparency depends largely on the color of the material, the thickness of the restoration walls (thickness), and the microstructures of the materials. All of these factors influence each other. Therefore, they are largely responsible for the final color result. They have a special effect on metal-free ceramic materials.
Other Important Factors Besides Color And Translucency
The natural tooth is a complex masterpiece. Its aesthetics is composed of several factors. Inside it is the dentin core, which is wrapped by transparent enamel. Dentin and enamel have different optical properties. For this reason, in addition to color or hue and translucency, many other factors are important for the aesthetic appearance of dental restorations:
- The brightness describes a brightness scale with ten graduated shades from black to white.
- Chromaticity refers to the saturation of the color or quality with which strong and pale colors are distinguished.
- Fluorescence describes the property of some materials to light up during lighting.
- Opalescence refers to the coloring of different substances depending on the incidence of light.
- The shape must fit the face with harmony.
- The contour reflects the characteristics of the surface, such as the texture and structure of the tooth.
Appropriate Technical Knowledge And Materials Needed
All these factors must be taken into account during the manufacture of a natural-looking restoration. The skill of the dental technician certainly plays a very important role in this regard. But even the best dental technician doesn’t just need technical knowledge and manual skills to get highly aesthetic results. Good materials are also indispensable, such as a suitable metal-free ceramic with the appropriate optical light properties.
Choice Of Suitable Restoration Material
From all this following is deduced: The requirements imposed on restoration materials are very high and complex. After all, each aesthetic restoration must be as individual, unique, and multifaceted as each person is.… Read More
