Description

Technical Field

[0001] The invention belongs to the field of oral orthodontics, and in particular relates to an indirect bonding bracket guide plate and a manufacturing method and a use method thereof. Background Art

[0002] At present, in traditional orthodontic treatment, the positioning of orthodontic brackets needs to be manually adjusted according to the specific situation of each patient. When positioning orthodontic brackets, doctors need to use precise measuring instruments to ensure the accurate position of brackets. There are strict requirements for bonding positioning. The positioning of brackets varies greatly among different doctors, which requires high technical level of doctors. At the same time, the accuracy is not high enough, the chairside operation time is long, the work efficiency is low, and the comfort of intraoral operation is not good for patients.

[0003] The split guide plate in the related art requires each group to be positioned and bonded separately, which is inconvenient to operate and prone to misalignment. The removal process is also inconvenient and time-consuming. In actual application, its convenience and efficiency are not high. Summary of the invention

[0004] The purpose of the present invention is to provide an indirect bonding bracket guide plate and a manufacturing method and a use method thereof, which have strong adaptability, high precision, improve work efficiency, improve patient comfort, and reduce the number of bracket positioning times.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] An indirect bonding bracket guide plate comprises a plurality of guide plate bodies and connecting rods. A bracket assembly portion and a guide plate occlusal surface are arranged on the side of the guide plate body close to the teeth. The guide plate occlusal surface matches the tooth occlusal surface. A connecting rod is arranged on the side of the guide plate body away from the teeth. All the guide plate bodies are connected by the connecting rods.

[0007] The connecting rod connects the separate guide bodies into an integral guide. Since the bracket guide is made of flexible material, the guide body can be easily worn by bending the connecting rod up and down, front and back, left and right to adjust its position. At the same time, the occlusal surface of the guide and the bracket assembly part are positioned to achieve precise positioning. It is suitable for complex corrections that require precise guidance and restriction of the direction of tooth movement.

[0008] Furthermore, the connecting rod includes a main rod and two branch rods. The main rod is located on the side of the guide plate body close to the cheek, and the branch rod is located on the side of the guide plate body close to the tongue. The main rod is U-shaped, and the two sides of the center of the main rod are forked into two branch rods.

[0009] A main rod and a supporting rod are provided at the molar, which are distributed on the buccal side and the lingual side, and can stably fix the entire guide plate structure. Furthermore, a handle is provided at the center of the main rod.

[0010] The handle can be used to initially position the guide plate. The handle also serves as a nameplate to record the number of the guide plate for easy identification and storage.

[0011] Furthermore, the bracket assembly part comprises a bracket assembly groove which passes through from top to bottom, a bracket tooth positioning end is arranged on the side of the bracket assembly groove close to the occlusal surface of the guide plate, and clamping grooves are arranged on both ends of the side of the bracket assembly groove away from the occlusal surface of the guide plate.

[0012] When the guide plate body is installed, the bracket is placed in the bracket assembly slot and fixed in position by the clamping slot.

[0013] Furthermore, the tooth positioning end of the bracket is provided with an inclination angle, and the inclination angle is inclined outwardly from the overflow channel to the bracket assembly groove.

[0014] The inclination angle of the bracket tooth positioning end can avoid the problem of tooth undercut, which is conducive to the positioning of the guide plate on the tooth, and the bonded guide plate can be smoothly removed.

[0015] Furthermore, an overflow channel is provided between the bracket assembly portion and the occlusal surface of the guide plate.

[0016] The overflow channel can effectively drain excess adhesive from the overflow channel, which is beneficial for cleaning residual adhesive.

[0017] A method for manufacturing an indirect bonding bracket guide plate comprises the following steps:

[0018] (1) Data collection: Obtain intraoral dental data through digital oral scanning or silicone rubber impression;

[0019] (2) Design: Based on the collected oral tooth data, the teeth are arranged through digital orthodontic software to form neat tooth shapes. Then, the bracket positioning and bracket bonding scheme is designed on the model. After the positioning design is completed, the three-dimensional guide plate is generated. The connecting rod is connected with the arrangement of each guide plate to avoid large-area islands during printing. During the printing process, each layer is connected and printed downwards through the connecting rod;

[0020] (3) Guide plate printing: The guide plate is placed at an angle of 45 degrees, with support added to the lip side. The three-dimensional data of the guide plate is placed in the 3D device and printed with IBT flexible resin. After printing, it is cleaned twice with 95% alcohol, and the residual alcohol on the surface of the guide plate is blown dry with compressed air. The guide plate is then cured for 5 minutes in a post-curing box to complete the finished guide plate.

[0021] A method for using an indirect bonding bracket guide plate comprises the following steps:

[0022] (1) Place the bracket in the bracket assembly slot and snap it into the slot to ensure that the bracket is assembled in place to prevent it from falling off;

[0023] (2) Apply adhesive evenly to each assembled bracket, and wear the guide plate coated with adhesive into the patient's mouth, with the teeth aligned with the occlusal surface of the guide plate;

[0024] (3) During the wearing process, the connecting rod is moved to guide and support the guide plate to adjust its direction, ensuring that the teeth can be gradually adjusted to the correct position;

[0025] (4) Check the bracket seating through the bracket assembly slot;

[0026] (5) Excess adhesive flows out from the overflow channel, and the adhesive overflowing around the adjacent channels of the guide plate is cleaned;

[0027] (6) After confirming that the bracket is inserted into the correct position, use a curing light to fix it. After fixation, take out the guide plate and then bond the bracket for secondary curing and reinforcement. After secondary curing, clean up the excess adhesive.

[0028] Due to the adoption of the above scheme, the present invention has the following beneficial effects:

[0029] 1. It has strong adaptability and is suitable for complex situations such as uneven alignment and poor occlusion. It can be flexibly adjusted up and down, left and right through the connecting rod of the guide plate, so that each guide plate body will not be deformed when worn and can be accurately positioned on each tooth.

[0030] 2. High precision: the bracket is directly positioned and bonded on the indirect bonding bracket guide, which can avoid the influence of soft tissue and saliva in the mouth, thereby greatly improving the accuracy of the bracket.

[0031] 3. Since most of the work has been completed on the model, the doctor only needs to make simple adjustments and bonding in the mouth, which can greatly save chairside operation time and improve work efficiency.

[0032] 4. It reduces the time patients spend opening their mouths, reduces discomfort, and improves patients' comfort.

[0033] 5. Accurate bracket positioning can reduce the number of bracket repositioning times, thereby shortening the correction time. BRIEF DESCRIPTION OF THE DRAWINGS
