Description

Technical Field

[0001] This utility model relates to the field of orthodontic appliance technology, specifically to a maxillary removable expander appliance with an anterior tooth spring anchorage enhancement structure. Background Technology

[0002] Slow maxillary expansion is a common method for addressing insufficient maxillary arch width development during the mixed dentition stage. It reduces pain and other side effects, and enhances the physiological response of bone growth and remodeling, utilizing the intrasuture osteogenic effect of the palatal midline to achieve skeletal expansion of the maxillary arch. The efficacy of slow maxillary expansion is supported by extensive clinical research data and is a mature early orthodontic technique for children. Clinically, acrylic resin-based removable expanders are commonly used for mild to moderate maxillary arch width development. The removable expander consists of an active force component, a retention component, and a connector. The active force component is a spiral expansion spring placed within the base. The retention component typically uses posterior tooth arrow clasps and / or interproximal hooks, bent from 0.7-0.9mm stainless steel; for anterior teeth, labial arches and / or arrow clasps are used. The connector is composed of an acrylic resin base, split in the middle, forming a horseshoe shape to cover the palatal side of the teeth and the palatal mucosa.

[0003] In the process of realizing this utility model, the inventors discovered that the following problems in the prior art have not been solved: the existing maxillary removable expander appliances have low tooth movement controllability and insufficient treatment efficiency, which urgently need to be improved. Therefore, we propose a maxillary removable expander appliance with an anterior tooth spring anchorage enhancement structure. Utility Model Content

[0004] The purpose of this invention is to provide a maxillary removable expander with an anterior tooth spring anchorage reinforcement structure, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a maxillary movable arch expander with an anterior tooth spring anchorage enhancement structure, comprising a force mechanism, a connector and a retention mechanism, wherein the force mechanism comprises an anterior tooth spring, a single-curved coil spring and a spiral arch expander spring;

[0006] The connector includes a palatal base, which is made of acrylic resin. The palatal base is split in the middle and is horseshoe-shaped, covering the palatal side of the teeth and the palatal mucosa. The arch-expanding part of the palatal base uses a spiral arch-expanding spring.

[0007] One end of the anterior tooth spring extends to the distal cervical region of the maxillary central incisor and holds the central incisor. The plane of the anterior tooth spring is perpendicular to the long axis of the tooth and forms a contact point.

[0008] The anterior tooth spring extends to one side of the palatal base, and a single-curved coil spring is provided at the connection between the anterior tooth spring and the palatal base.

[0009] The retention mechanism includes a posterior tooth arrow holder, an anterior tooth double-curved labial arch, and a gap holder. The anterior tooth double-curved labial arch bends distally from the canines into the connector and can be used in conjunction with the anterior tooth spring and connector assembly. During maxillary removable arch expander treatment, after the appliance is installed, an anterior tooth spring is placed at the front of the expander device. Its elastic deformation applies a controllable force to the anterior teeth, directionally distributing the arch expansion effect. This increases the arch circumference while closing the maxillary central incisor gap, guiding the lateral incisors to erupt correctly, increasing anterior tooth anchorage stability, and improving treatment efficiency. The results are quite ideal.

[0010] As an optional solution to the technical solution of this application, the other end of the anterior tooth spring is bent from the lingual cervical margin of the tooth to the palatal side at the distal 1 / 3-1 / 2 of the crown, and the anterior tooth spring enters the palatal base of the connector. The mesial palatal base of the coil spring in this area needs to be buffered to avoid obstructing the adjustment of the coil spring.

[0011] As an optional solution to the technical solution of this application, the connection between the anterior tooth spring and the palatal base forms a buffer zone. The mesial palatal base that can pass through this area needs to be buffered to avoid obstructing the adjustment of the coil spring.

[0012] As an optional solution to the technical solution of this application, the anterior tooth spring is an arc-shaped elastic metal wire, bent from stainless steel with a diameter of 0.5mm. The elastic metal wire has good elasticity, and the steel wire of a suitable diameter meets the orthodontic needs of this product.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention relates to a maxillary removable arch expander with an anterior tooth spring anchorage enhancement structure. By incorporating an anterior tooth spring and a connector, during maxillary removable arch expander treatment, after the appliance is installed, the anterior tooth spring, positioned at the front of the expander, applies a controllable force to the anterior teeth through its elastic deformation. This directs the expansion effect, thereby increasing the arch circumference while closing the interdental space between the maxillary central incisors, guiding the correct eruption of the lateral incisors, increasing anterior tooth anchorage stability, and improving treatment efficiency. The results are quite satisfactory. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1-2 This utility model provides a technical solution: a maxillary removable expander orthodontic appliance with an anterior tooth spring anchorage enhancement structure, comprising a force mechanism 1, a connector 2, and a retention mechanism 3. The force mechanism 1 includes an anterior tooth spring 101, a single-curved coil spring 102, and a spiral expander spring 103. The connector 2 includes a palatal base 201, which is partially composed of an acrylic resin base. The palatal base 201 is split in the middle and is horseshoe-shaped, covering the palatal side of the teeth and the palatal mucosa. The expander portion of the palatal base 201 uses a spiral expander spring 103. One end of the anterior tooth spring 101 extends to the distal cervical region of the maxillary central incisor and holds the central incisor. The plane of the anterior tooth spring 101 is perpendicular to the long axis of the tooth and forms a contact point. The other end of the anterior tooth spring 101 is bent from the lingual cervical margin of the tooth at the distal 1 / 3-1 / 2 of the crown towards the palatal side, and the anterior tooth spring 101 enters... The palatal base 201 of connector 2 allows the anterior tooth spring 101 to be properly positioned and connected to the base, achieving the desired orthodontic effect. The connection between the anterior tooth spring 101 and the palatal base 201 forms a buffer zone 202, which buffers the mesial palatal base 201 through the coil spring in this area to avoid obstructing the adjustment of the coil spring. The anterior tooth spring 101 is an arc-shaped elastic metal wire bent from 0.5mm diameter stainless steel. The elastic metal wire has good elasticity, and the appropriate diameter of the wire meets the orthodontic requirements of this product. The anterior tooth spring 101 extends to one side of the palatal base 201, and a single-curved coil spring 102 is provided at the connection between the anterior tooth spring 101 and the palatal base 201. The retention mechanism 3 includes a posterior tooth arrow holder 301, an anterior tooth double-curved labial arch 302, and a gap holder 303. The anterior tooth double-curved labial arch 302 bends distal to the canine and enters connector 2.

[0021] In this technical solution, the anterior tooth spring 101 and the connector 2 assembly can be used together. During the maxillary removable arch expander orthodontic treatment, after the orthodontic appliance is installed in place, the anterior tooth spring 101 is set in front of the arch expander. Its elastic deformation is used to apply a controllable force to the anterior teeth, and the arch expansion effect is directionally distributed. This increases the perimeter of the dental arch while closing the space between the maxillary central incisors, guiding the lateral incisors to erupt correctly, increasing the anchorage stability of the anterior teeth, and improving the orthodontic efficiency. The effect is quite ideal.

[0022] Working principle: It should be noted that this utility model is a maxillary movable expander orthodontic appliance with an anterior tooth spring anchorage enhancement structure. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be known to those skilled in the art through technical manuals or conventional test methods.

[0023] When using a maxillary removable expander appliance with an anterior tooth spring anchorage enhancement structure, the maxillary removable expander appliance is transported to the designated area, and then the force mechanism and retention mechanism are properly positioned. The connector is then placed in place and connected to each mechanism for orthodontic treatment.

[0024] By incorporating anterior tooth spring 101 and connector 2, during the maxillary removable arch expander orthodontic treatment, after the appliance is installed in place, the anterior tooth spring 101 is placed at the front of the expander device. Its elastic deformation applies a controllable force to the anterior teeth, directionally distributing the arch expansion effect. This increases the arch circumference while closing the maxillary central incisor space, guiding the lateral incisors to erupt correctly, increasing the anchorage stability of the anterior teeth, and improving treatment efficiency. The results are quite ideal.
