Bracket positioning guide plate and using method thereof

Abstract

The invention discloses a bracket positioning guide plate, which comprises several independent guide plates, the independent guide plate comprises a lip side positioning plate, a horizontal stabilizing plate and a tongue side retaining plate; the invention further provides a using method of the bracket positioning guide plate, firstly, a long axis of a tooth body is drawn on a tooth model; a firstbonding layer is laid on the lingual side of a tooth occlusal surface; then an independent guide plate in a proper shape is selected to be placed at the first bonding layer, the horizontal stabilizing plate abuts against the tooth cutting edge or the tooth tip, the lip side positioning plate abuts against the tooth lip face, the center line of the lip side positioning plate coincides with the long axis of the tooth, and finally a second bonding layer is laid on the surfaces of the horizontal stabilizing plate, the tongue side fixing plate and the first bonding layer. The independent guide plate can be used for positioning the mounting position of the bracket on a certain tooth, the independent guide plate of the lip side positioning plate with a proper shape is selected for positioning the bracket of each tooth, the operation is similar to movable type printing, the procedure of individually customizing a plastic plate is omitted, and the bracket positioning difficulty and the positioning cost are reduced.

Description

technical field [0001] The invention relates to the technical field of orthodontic instruments and peripheral supporting facilities, in particular to a bracket positioning guide plate and a method for using the same. Background technique [0002] Orthodontics is the straightening of teeth Deformity, orthodontics mainly studies malocclusion The etiological mechanism of deformity, diagnosis analysis and its prevention and treatment, orthodontics can achieve the effect of beautiful teeth. [0003] Brackets are an important part of fixed orthodontic technology. They are directly bonded to the crown surface with adhesives, and arch wires pass through the brackets to exert various types of orthodontic forces on the teeth. Brackets are made of stainless steel, bioceramic or composite resin, and their main function is to fix the arch wire, so that the arch wire can play a better role and transmit the orthodontic force, so as to control the three-dimensional movement of the teeth...

Problems solved by technology

[0004] In the prior art, in order to accurately fix the brackets, it is first necessary to glue the brackets on the model according to the patient’s tooth model, and then use 3D printing technology to make a personalized resin guide plate, which is used in the patient’s oral cavity to position , Install the brackets, the positioning and installation process is time-consuming and laborious, and the cost of making personalized resin guide plates is relatively high
