Description

Buccal tube with movable traction member

Technical field

The invention relates to the technical field of orthodontic appliances, in particular to a buccal tube.

Background technique

The buccal tube is an important part of the orthodontic fixation appliance, which is composed of a hollow tube, a traction hook and a bottom plate. In general, the buccal tube is directly pasted or fixed on the molar tooth surface through a band paste, and the correction arch wire passes through the hollow tube of the buccal tube, and the buccal tube can serve as a fixation of the arch wire. There is a traction hook on the buccal tube, which is used to hang rubber bands or tension springs for intra-jaw or inter-jaw traction. Usually the traction hook is not used throughout the entire orthodontic cycle, but only used in the early or middle and late stages of orthodontics. However, the traction hooks set on the buccal tubes currently on the market are all fixed traction hooks. The current buccal tube The towing hook cannot be removed when the towing hook is not in use. Due to its functional requirements, the structure of the traction hook stimulates the oral mucosa, which is easy to give patients a strong foreign body sensation. In addition, the traction hooks on the market all contain a sharp angle structure, which brings discomfort to the patient. In order to reduce the foreign body sensation of the patient, the provision of a buccal tube that the traction hook can receive when not in use can greatly reduce the discomfort caused to the patient during the use of the buccal tube.

Our company’s previous patent application CN110584810A discloses a buccal tube with a concealable traction hook. An accommodating space is provided in the main body of the buccal tube, and the movable or rotating traction hook is placed in the main body when not in use. In the accommodating space inside, the towing hook is moved or rotated out of the accommodating space during use. However, there are three problems with the proposed solution: First, because the buccal tube is used to stick to the molars, its size is very small, the size of the main body is only 3-6mm, and the length of the traction hook is usually 1- About 3mm, an accommodating space is provided inside the main body, and a movable or rotating traction hook must be assembled in the accommodating space. Because the size is too small, the processing procedures are complicated and difficult in the actual production and processing process. Because of the difficulty in processing, the accuracy of the product is not ideal, the yield of the product is low, and it is difficult to maintain stability after the towing hook is repeatedly moved or rotated; second, because the towing hook is set in the accommodating space in the main body, Moreover, the size of the traction hook is very small, and the buccal tube is glued to the patient’s molars, which is located deep in the oral cavity. During the actual operation, the doctor cannot observe the position of the traction hook on the buccal tube with the naked eye. The towing hook is taken out from the internal accommodating space. It is difficult to align the tool with the towing hook. If the operation is wrong, the tool is very easy to scratch the patient’s mouth; third, because the processing procedure is complicated and difficult, the processing cost is high. Market promotion and application are very difficult. In order to meet the needs of practical applications, it is necessary to improve the technical solutions in the above application, and design a method that can avoid the traction hook from irritating the patient’s oral mucosa when not in use, the actual production and processing difficulty is low, it is convenient for doctors to operate, and the production cost can be a market environment. Accepted buccal tube.
