Embodiment 1

[0037] A dental bleaching guide plate, comprising a first plate 1 and a second plate 2, the first plate 1 and the second plate 2 are butted to form an enclosed deep groove structure, the first plate 1 is provided with a guide hole 3, and the first plate 1 and the second plate 2 The distance between the two opposite sides of the plate 1 and the second plate 2 is larger than the outer diameter of the tooth neck, so that the teeth can be inserted into the deep groove, and the sides of the first plate 1 and the second plate 2 and the side of the teeth have gap.

[0038] Specifically, the first plate 1 and the second plate 2 are both plate-like structures, and the plate structures of the first plate 1 and the second plate 2 are adapted to the outer contour of the dentition formed by the arrangement of a plurality of teeth. The thickness, width and length of the plate 1 and the second plate 2 can be designed to be equal or unequal, or partially equal according to the size of the tee...

Embodiment 2

[0043] A preparation method of a dental bleaching guide, comprising the following steps:

[0044] 1. For patients who need external bleaching in different areas, after the doctor completes the clinical diagnosis and the judgment of indications, the doctor will use the oral scanning equipment or model scanning equipment to collect the digital model of the patient's mouth, and collect the color photos of the patient's teeth in the mouth, and use electronic colorimetry. The instrument compares the color number of the color photo of the abutment with the color photo of the patient's teeth, so as to obtain the colorimetric data of the teeth;

[0045] 2. Import the colorimetric information into the dental design software Exocad; use the occlusal splint design function in the dental design software to load the patient's intraoral model to design and make the guide plate.

[0046] Specifically:

[0047] S201: Determine the degree of discoloration of the teeth according to the colorimet...

Abstract

The invention discloses a dental bleaching guide plate and a preparation method thereof, comprising a first plate and a second plate, the first plate and the second plate are butted to form an enclosed deep groove structure, and the first plate is provided with a guide hole, The distance between the two opposite sides of the first plate and the second plate is greater than the outer diameter of the tooth neck of the tooth, so that the tooth can be inserted into the deep groove, and the sides of the first plate and the second plate have a gap with the side of the tooth; The guide plate can be placed on the outside of the teeth to isolate the area of ​​teeth that need to be bleached from the area of ​​non-bleached teeth, which can prevent the bleaching agent from contacting the rest of the teeth. The purpose of accurately controlling the smearing range, smearing amount, zonal coloring and bleaching, and accurately locating the administration position is achieved.

Description

technical field [0001] The invention relates to the technical field of tooth bleaching, in particular to a dental bleaching guide plate and a preparation method thereof. Background technique [0002] As an effective means to improve pigmented teeth, pulp tooth bleaching has been widely used in clinical practice. The activated pulp tooth whitening agent used in pulp tooth bleaching mainly relies on the oxidant in its composition to exert its bleaching effect. The type and concentration of the oxidant will affect the bleaching effect. At present, the main component of oxidant is hydrogen peroxide. The high permeability of small molecule hydrogen peroxide can lead to different degrees of tooth sensitivity, resulting in different degrees of damage to the pulp and the periodontal around the affected tooth. In clinical use, the pulp-vitrifying whitening agent is usually smeared on the teeth by hand. This cannot precisely control the scope and amount of smearing, which will affect...
