Problems solved by technology

The fixed arch expander is a screw device, which is fixed on the tooth covers on both sides through the pull rod, and the tooth covers are fixed on the teeth on both sides. The size, the distance between the front and rear teeth on both sides is basically the same, it is difficult to adapt to the clinically complex arch expansion requirements, and the size of the expanded dental arch is not accurately quantified, resulting in the blindness of the front and rear expansion of the dental arch

Embodiment approach 1

[0040] see figure 1 , figure 2 , image 3 with Figure 4 , figure 1 It is a structural schematic diagram of an embodiment of the dental arch expander of the present invention, figure 2 It is a structural schematic diagram of installing the second bracket in an embodiment of the dental arch expander of the present invention, image 3 It is a structural schematic diagram of installing the third bracket in an embodiment of the dental arch expander of the present invention, Figure 4 It is the operation flowchart of the dental arch expander of the present invention. The dental arch expander of the present invention includes two dental crowns 1 and brackets 2 , wherein the two dental crowns 1 are installed on the teeth on both sides respectively, and the brackets 2 are fixed between adjacent dental crowns 1 .

[0041] Such as Figure 1 to Figure 3 As shown, the braces 1 are made of transparent hard materials, and the braces 1 made of transparent materials are convenient fo...

Embodiment approach 2

[0054]see Figure 5 , Figure 5 It is a structural schematic diagram of another embodiment of the dental arch expander of the present invention. The dental arch expander of the present invention provides a second embodiment, which specifically includes two dental crowns 1 and brackets 2, wherein the two dental crowns 1 are respectively installed on the teeth on both sides, and the brackets 2 are fixed between the adjacent dental crowns 1 between.

[0055] The difference between the second embodiment and the first embodiment is that the middle part of the bracket 2 has a helical structure, and its two ends are linear bending parts.

[0056] Such as Figure 5 As shown, there are three supports 2, namely the first support 2, the second support 2, and the third support 2, and the above three supports 2 are arranged side by side. When the three supports 2 are specifically installed, the installation steps are as follows: Figure 4 as shown, Figure 4 The operation method of a...

Abstract

The invention relates to a dental arch expansion device and an operation method thereof. The dental arch expansion device comprises at least two braces and stents, wherein the braces are mounted on teeth on two sides respectively, and each stent is fixed between the adjacent braces. The dental arch expansion device has the superior effects as follows: with the adoption of the brace and stent matched structure, the dental arch expansion device has directionality during arch expansion, and the tooth correction reliability is improved; the stents are simple in structure and convenient to dismount, after the device is worn by a patient, the oral foreign body sensation is small, the ulcer incidence is low, the correction effect is good, and health of teeth is facilitated. According to the dental arch expansion device, adaptive arch expansion is performed in accordance with distance to be enlarged in front and behind the dental arch, and accordingly, the problem that the final arch expansion result is inconsistent with the design goal is solved.

Description

technical field [0001] The invention relates to the technical field of orthodontic appliances, in particular to a movable appliance in orthodontic appliances in stomatology, in particular to a dental arch expander and an operating method thereof. Background technique [0002] Existing dental arch expanders are mainly fixed arch expanders. The fixed arch expander is a screw device, which is fixed on the tooth covers on both sides through the pull rod, and the tooth covers are fixed on the teeth on both sides. The size, the distance between the front and rear teeth on both sides is basically the same, it is difficult to adapt to the clinically complex arch expansion requirements, and the size of the expanded dental arch is not accurately quantified, resulting in the blindness of the front and rear expansion of the dental arch. Contents of the invention [0003] A main purpose of the present invention is to overcome at least one defect in the prior art, and provide a dental ...
