Description

Technical Field

[0001] The utility model relates to the technical field of dentistry, and more specifically to an invisible tooth corrector. Background Art

[0002] Orthodontics usually refers to correcting misaligned teeth through oral techniques. Among them, the large gaps between teeth caused by misaligned teeth are also a problem that needs to be solved urgently. Orthodontics usually uses invisible dental braces to minimize the impact of the correction process on the user's life.

[0003] In the prior art, a dental brace made of a polymer transparent elastic material is a series of continuous movable appliances, which achieves the purpose of dental correction by continuously moving teeth in a small range. However, in the existing solutions, the movable appliances need to be constantly replaced, and the movable appliances need to be reconfigured regularly according to the user's dental correction situation, which increases the cost of dental correction. At the same time, the process of replacing the movable appliances is time-consuming, affecting the user's work and life. In addition, the movable appliances are generally large and wrap around the teeth, which makes the user feel a serious foreign body in the mouth, affecting the user's daily life. An existing patent is an invisible dental brace. Patent announcement number CN217488892U uses the convenient rotation and fixation of the central axis through the joint cooperation of a central axis, an I-shaped wire groove block, an elastic rope, etc., and successfully realizes the tightening of two or more shells connected by an elastic rope, thereby conveniently and quickly adjusting the force between two or more teeth, and realizing the correction of the excessive gap between teeth. The structure is simple and light, so the manufacturing cost is low, which greatly reduces the user's foreign body sensation in the mouth and is easy to use.

[0004] However, in patent announcement No. CN217488892U, when it is necessary to increase the force of the elastic rope on the teeth to promote the correction of excessive gaps between teeth, it is only necessary to lift the top column sleeve upwards to disengage the clamping rod from the clamping notch, and then rotate the clamping rod to make the central axis start to rotate. At this time, the disc block is lifted and rotates on the inner wall of the spring cavity column, the first spring is compressed, and the I-shaped wire groove block starts to rotate, thereby winding the elastic rope, so that the elastic rope is tightened. Due to the small size of the top column sleeve and the clamping rod, and the need to operate inside the oral cavity, the operation is difficult. In order to facilitate manual correction at work, we have proposed an invisible dental braces to solve the above-mentioned problems. Utility Model Content
