Description

Technical Field

[0001] The utility model relates to the technical field of medical oral treatment instruments, in particular to an auxiliary mechanism of an oral orthodontic positioner. Background Art

[0002] Orthodontics is generally divided into fixed metal bracket correction, fixed self-ligating bracket correction, transparent ceramic bracket correction, and bracketless invisible bracket correction. The most common ones are fixed metal bracket correction or fixed self-ligating bracket correction. When patients choose fixed metal bracket correction or fixed self-ligating bracket correction, they need the attending physician to bond the braces to the surface of the teeth. During the bonding process, the attending physician often visually inspects the bonding position of the braces and relies entirely on clinical experience for the operation. Inaccurate bonding position will directly lead to poor treatment results in the later stages. Visual bonding often results in large errors, resulting in low treatment efficiency and poor orthodontic effects. If the position of the braces is inaccurate, the correction will fail.

[0003] In the prior art, such as the Chinese patent CN 211300421 U, there is an orthodontic positioner, which includes a connecting frame, and a fixed arm and a movable arm connected to the connecting frame. The inner side of the fixed arm is provided with a mounting groove, and a disposable gasket is embedded in the mounting groove. An arc-shaped ruler is fixed in the middle of the fixed arm, and a limit groove is opened on the ruler. A limit bolt and a limit plate are installed on the limit groove. The ruler passes through the movable arm, and a spring is sleeved on the ruler between the fixed arm and the movable arm. A fixed ring is provided on the outer side of the lower part of the movable arm, and a marking pen is provided in the fixed ring. A limit card plate is provided below the marking pen, and one end of the limit card plate is inserted into the lower part of the movable arm. The dentist determines the bonding position by the ruler and the limit card plate, so that the bracket can be accurately bonded and fixed on the teeth, and the bonding is more accurate. Accurate bonding can simplify the treatment process, shorten the treatment time, and improve the treatment efficiency. The disposable protective film and disposable gasket can ensure oral hygiene and avoid cross infection. It is suitable for promotion and use. However, the patent still has the following problems.

[0004] In the above patent, although the patented marking pen is used to draw the accurate bonding position, some patients have abnormally shaped teeth and their teeth are tilted, and the position of the marking pen is fixed. Therefore, when marking, the marking pen may have difficulty in contacting the teeth, which may cause the bracket to be difficult to bond and fix on the teeth accurately, reducing the treatment efficiency.

During installation, the staff inserts the marking pen 11 into the fixing seat 8, and the fixing seat 8 pushes the first clamping block 17 to move so that it enters the first limiting groove 15. When the first clamping slot 14 moves to the side of the first clamping block 17, the first clamping block 17 enters the first clamping slot 14 under the elastic force of the second spring 16, fixes the marking pen 11, and facilitates the replacement of the marking pen 11. When replacing the gasket 13, the staff pulls the L-shaped plate 34, and the L-shaped plate 34 drives the second block 33 to move, and the second block 33 enters the second limiting groove 31, and the third spring 32 is compressed. Then the staff pulls out the gasket 13, lowers the new gasket 13 and inserts it into the connecting groove 29, and then releases the L-shaped plate 34. The second block 33 enters the second groove 30 under the elastic force of the third spring 32 to fix the gasket 13.
