specific Embodiment approach

[0054] According to a specific embodiment, the dental color selection and color query system for the present invention includes the following modules:

[0055] 1) Dental CCS / CCM module:

[0056] The background database of the color selection program includes: ① Vita Lumin Vacuum shade guide, Vita 3D Master shade guide, Vita In-Ceram technician shade guide, Vita In-Ceram YZ staining solution color guide middle 1 / 3 chromaticity value. Among them, Vita Lumin Vacuum shade guide and Vita 3D Master shade guide also include the chromaticity value of 1 / 3 of the neck and cut part. ②Chromaticity values ​​of Vita In-Ceram Alumina crowns, Vita In-Ceram YZ crowns, AGC aluminum ceramic crowns, and Y-TZP zirconia crowns, among which Vita In-Ceram Alumina decorative porcelain and Vita gold porcelain restoration materials , Artglass materials are made according to the situation of natural teeth to make customized color charts, and the measured chromaticity value of the incisal part of the nec...

Abstract

The invention provides a dental color fitting and color inquiry system, which comprises a chromatic value input unit, a data storage unit, a color difference analysis unit and a searching output unit, wherein the chromatic value input unit is connected with the color difference analysis unit and is used for inputting the chromatic value of a natural tooth to be repaired into the color difference analysis unit; the data storage unit is used for storing chromatic values of various repairing materials; the color difference analysis unit is connected with the data storage unit, and is used for comparing the chromatic value of the natural tooth input by the chromatic value input unit with the chromatic values of the various repairing materials stored in the data storage unit to obtain a color difference value and transmitting the color difference value to the searching output unit; and the searching output unit is used for finding out a shade guide with the smallest color difference value from the selected repairing material by data searching. By adopting the dental color fitting and color inquiry system, the dental color fitting and color inquiry can be automatically and accurately carried out.

Description

technical field [0001] The invention relates to a color selection and color query system, in particular to a dental color selection and color query system. Background technique [0002] Color matching used to be done by the colorist based on intuition and experience, the rate of approaching the target color is very slow, the accuracy is poor, and it takes a long time. With the rapid development of science and technology today, the use of color engineering knowledge and the intervention of computers will solve this problem. This method is called computer color matching (CCM). The principle of CCM is to use the bisection method or the Newton-Raphson method to solve it by successive approximation, and to efficiently approach the target color. The colors obtained by CCM are generally metamerisms. When the conditions change, color mismatch will occur. As a restoration with high simulation requirements, there will be problems. Therefore, the color matching should also be carried ...
