Said invention also provides the concrete connection mode of all the above-mentioned components and concrete application method of said tooth colorimeter.
Description
Technical field
The present invention relates to a kind of colour comparatour, particularly a kind of tooth color comparator and measuring method thereof are used for dental treatment, dental repair, making artificial tooth, the creamy white contrast before and after the tooth whitening.
Background technology
When dental treatment, dental repair, tooth whitening, making artificial tooth, the doctor need measure the color of patients teeth, selects to have identical or the most close repair materials then, and tooth is repaired.Present clinical employing be artificial vision's colorimetric method, that determine tooth and repair materials distinguishes whether color consistent, quite the difficulty, extremely inaccurate.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of tooth color comparator that detects color of teeth with the light source and the single bundle of the employing reflected colour light ratio example measuring method of LED, be used for dental treatment, dental repair, making artificial tooth, the creamy white contrast before and after the tooth whitening.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of tooth color comparator, LED is positioned at same central axis, corresponding in opposite directions installation in the enclosure with the light harvesting head of soft fiber, the other end of soft fiber inserts probe and along the inwall uniform distribution of popping one's head in, the center is cylindrical space; One end of lamp guide inserts the central cylindrical space of probe, and both are positioned same central axis, and the other end of lamp guide inserts every light box, and is positioned at same central axis, corresponding in opposite directions being installed in every light box with photoelectric sensor; Photoelectric sensor is connected successively by boundling holding wire and circuit board and the display screen that is provided with little process chip, and LED is connected with circuit board by lead with battery; The tip that probe stretches out shell, display screen is installed in the rear end of shell, and remaining original paper is installed in the enclosure.
A kind of measuring method of tooth color comparator: connect the power supply of LED earlier, with the close detected tooth of probe; The light that LED sent through light harvesting head, soft fiber from the surface of the detected tooth of the cylindrical luminous zone directive of probe and enter the tooth deep layer.Because tooth is a translucent body, and the creamy white of various teeth is deep mixed, and is different to the absorption of light, so the coloured light composition that is reflected is also different.Enter the lamp guide directive through the foveal reflex light district of probe by single bundle coloured light of dental surface and deep reflex and be positioned at tricolor photoelectric pick off, and be converted to three signals of telecommunication by it and pass to circuit board and be provided with the display screen of little process chip through the boundling holding wire every light box.
Circuit board and be provided with the display screen of little process chip according to three signals of telecommunication, coloured light or main component proportion are wherein analyzed and are differentiated color class, the depth of detected tooth, and compare the classification under the color that directly shows detected tooth on the screen with selected creamy white sorted spectrum.
The creamy white sorted spectrum is to carry out colour examining under standard conditions, by the various color classes and the depth thereof, is divided into A, B, C, D class, is further divided into 1,2,3,4 grade at each apoplexy due to endogenous wind.The creamy white sorted spectrum can be imported little process chip data base, creamy white that tooth color comparator records and the standard colour chart among the data base compare, and determine automatically and show to detect the affiliated classification of color of teeth.
The invention has the beneficial effects as follows:
1. artificial vision's colorimetric method of the clinical employing of dentistry at present, depend on accurate understanding and the grasp of doctor to color, also can be subjected to the influence of subjective factorss such as light source, surrounding and emotion simultaneously, extremely inaccurate, cause the color of selected patching material different, influence the quality of dental repair, tooth whitening, making artificial tooth with the tooth primary colors.The present invention can determine and show the classification under the detection color of teeth automatically, is convenient to the doctor and selects for use the repairing that is in the same color classification in the creamy white sorted spectrum to make material, makes the tooth of repairing or the solid colour of artificial tooth and dermal tooth, reaches the effect of beauty treatment.
2. adopt the light source volume of LED little, easy to use.
3. single bundle reflected colour light ratio example measuring method of the present invention only needs a lamp guide, and tooth color comparator is simple in structure, volume is less, easy to use, easy to manufacture, with low cost.

Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is a schematic appearance of the present invention.
Fig. 4 is the B-B profile of Fig. 3.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples
Embodiment 1 is as Figure 1-3: a kind of tooth color comparator, LED 12 is positioned at same central axis, the corresponding in opposite directions shell 11 that is installed in the light harvesting head 4 of soft fiber 7, the other end of soft fiber 7 inserts the inwall uniform distribution of probe 9 and edge probe 9, and the center is cylindrical space; One end of lamp guide 8 inserts the central cylindrical space of probe 9, and both are positioned same central axis, and the other end of lamp guide 8 inserts every light box 5, and is positioned at same central axis, corresponding in opposite directions being installed in every light box 5 with photoelectric sensor 6; Photoelectric sensor 6 is connected successively by boundling holding wire 3 and circuit board 2 and the display screen 1 that is provided with little process chip, and LED 12 is connected with circuit board 2 by lead with battery 13; Probe 9 tips of stretching out shell 11, display screen 1 is installed in the rear end of shell 11, and remaining original paper is installed in the shell 11.
Embodiment 2 is shown in Fig. 1-4: a kind of measuring method of tooth color comparator: the closed on and off switch 14 of elder generation, will pop one's head in 9 again near detected teeth 10.The light that LED 12 is sent through light harvesting head 4, soft fiber 7 from the surface of 9 the detected tooth 10 of cylindrical luminous zone 15 directives of popping one's head in and enter the tooth deep layer.Because tooth is a translucent body, and the creamy white of various teeth is deep mixed, and is different to the absorption of light, so the coloured light composition that is reflected is also different.Enter lamp guide 8 directives through 9 the foveal reflex light district 16 of popping one's head in by single bundle coloured light of dental surface and deep reflex and be positioned at tricolor photoelectric pick off 6, and be converted to three signals of telecommunication by it and pass to circuit board 2 and be provided with the display screen 1 of little process chip through boundling holding wire 3 every light box 5.Circuit board 2 and be provided with the display screen 1 of little process chip according to three signals of telecommunication, coloured light or main component proportion are wherein analyzed and are differentiated color class, the depth of detected tooth, and compare the classification under the color that directly shows detected tooth on the screen with selected creamy white sorted spectrum.
Experimental results show that: the ratio of contained green is basic identical in the reflection coloured light of various teeth, thus when the establishment computer software, can simplify procedures, as long as analyze and differentiation redness and blue ratio.
