A shade guide structure applied to the restoration of dental fluorosis

Abstract

The invention discloses a shade guide structure applied to the restoration of dental fluorosis, which comprises a positioning groove (1) with a hollow elongated tubular structure as a whole, and the cross section of the positioning groove (1) is a square structure. The upper top surface of the middle part of the positioning groove (1) vertically extends upwards the upper positioning groove (2) communicating with its interior, and the lower bottom surface of the middle part of the positioning groove (1) vertically extends downwards a lower positioning box communicating with its interior (3), the bottom of the lower positioning box (3) is equipped with a handle (4). The invention is easy to operate, and a single tooth color mark can be exposed for separate color matching comparison in one operation, which effectively eliminates the situation of visual inertia contrast color difference caused by observing a large number of tooth color marks at one time.

Description

technical field [0001] The invention relates to the technical field related to dental restoration appliances, in particular to a shade guide structure applied to the restoration of dental fluorosis. Background technique [0002] Dental shade guides are equipment used in dental restorations. Most of the common shade guides on the market are long strip structures. The generated birefringent optical path difference is arranged in order. In the process of color matching, the human eye will observe a large number of tooth color marks for a long time, which will lead to continuous comparison of visual inertia and contrast color interference. When the dentist looks at a After one color and then looking at another color, we will superimpose the complementary color of the previous color on the latter color. This is because the visual "afterimage" produced by our continuous staring at one color directly affects its test. This visual "afterimage" phenomenon is particularly obvious for...

[0002] Dental shade guides are equipment used in dental restorations. Most of the common shade guides on the market are long strip structures. The generated birefringent optical path difference is arranged in order. In the process of color matching, the human eye will observe a large number of tooth color marks for a long time, which will lead to continuous comparison of visual inertia and contrast color interference. When the dentist looks at a After one color and then looking at another color, we will superimpose the complementary color of the previous color on the latter color. This is because the visual "afterimage" produced by our continuous staring at one color directly affects its test. The accuracy of the teeth, especially the tooth color scales with many color numbers and located on the same visual horizontal line, this visual "afterimage" phenomenon is particularly obvious
