Embodiment 1

[0031] This embodiment provides a detachable and wearable residual root traction corrector, such as Figure 1-3 As shown, the residual root traction corrector includes a transparent retainer 1, a traction hook 2, a traction bracket 3 and an elastic member 4, the transparent retainer 1 is detachably sleeved on the dental arch, and the traction bracket 3 Connected to the labial side of the transparent retainer 1, the traction hook 2 is used to be connected in the root canal of the tooth root to be tracted, and the lingual side of the transparent retainer 1 is provided with an opening exposing the traction hook 2, so Both ends of the elastic member 4 are respectively connected to the traction bracket 3 and the traction hook 2 and straddle the tooth root to be tracted;

[0032] The traction hook 2, the traction bracket 3 and the elastic member 4 are one or more groups, and the number of groups of the traction hook 2, the traction bracket 3 and the elastic member 4 is equal to the ...

Embodiment 2

[0035] The residual root traction corrector as described in embodiment 1, such as figure 1 with 2 As shown, the traction bracket 3 includes a traction bracket body 6 and a traction bracket limit hook 5, the elastic member 4 is a rubber ring, one end of the rubber ring is sleeved on the traction hook 2, and the other end is It is clamped between the limit hook 5 of the traction bracket and the lip side of the transparent holder 1 .

[0036] For residual root teeth in different situations, it is necessary to use different strengths for traction correction. The residual root traction corrector of this embodiment, by selecting rubber rings with different elastic forces, or for the same rubber ring, after being connected to the traction hook 2 and The stretching state of the rubber ring is different when the brackets are pulled between the stop hooks 5, and then the correction force of the residual root traction aligner on the residual root teeth can be easily adjusted, that is, t...

Embodiment 3

[0038] The residual root traction corrector as described in embodiment 1, such as figure 2 As shown, the traction bracket 3 is connected to the middle 1 / 3 height of the lip side of the transparent holder 1 corresponding to the tooth surface. The upper 1 / 3 of the transparent holder 1 means that the transparent holder 1 is located figure 2 At the highest position above the direction shown in the figure, the lower 1 / 3 of the transparent holder 1 means that the transparent holder 1 is located figure 2 At the lowest position below the direction shown in the figure, the middle 1 / 3 height of the transparent holder 1 refers to the position where the distance from the bottom of the transparent holder 1 is 1 / 3 of the height of the transparent holder 1 itself. The traction bracket 3 is connected to the 1 / 3 height of the lip side of the transparent retainer 1, and then, the two ends of the elastic member 4 are respectively connected to the traction bracket 3 and the traction hook 2 an...

Abstract

The invention discloses a removable residual root traction corrector and a manufacturing method thereof. The residual root traction corrector comprises a transparent retainer, a traction hook, a traction bracket and an elastic piece, wherein the transparent retainer detachably sleeves a dental arch; the traction bracket is connected to the lip side surface of the transparent retainer; the tractionhook is used for being connected into a root canal of a tooth root to be subjected to traction; an opening for exposing the traction hook is formed in the tongue side surface of the transparent retainer; and two ends of the elastic piece are respectively connected with the traction bracket and the traction hook and are arranged on the tooth root to be pulled in a crossing manner. The residual root traction corrector disclosed by the invention can be conveniently connected to the tooth root to be subjected to traction, can be removed once discomfort exists in the using process, and is convenient to clean and disinfect; and the residual root traction corrector can be used for quickly performing traction on the residual root, the strength is easy to adjust, the comfort of a patient is good,and the residual root traction corrector is not easily influenced by occlusion during pulling.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a detachable and wearable residual root traction appliance and a manufacturing method thereof. Background technique [0002] Residual roots are often caused by caries, trauma, or wear, resulting in tooth defects and becoming residual roots, which lose their normal occlusal ability and cannot play a role in chewing. Some residual roots need to be removed surgically, while the other part of the residual roots need to be removed by traction. Orthodontics can achieve a good restoration effect; especially in clinical practice, it is often encountered that the crown fractures to the subgingiva. The commonly used methods for such residual roots are fixed orthodontic traction or crown lengthening to achieve the utilization of residual roots. purpose; the existing residual root traction correction often needs to connect many hard metal traction parts on the residual root and the surr...
