Description

Technical Field

[0001] The invention relates to the technical field of tooth correction, in particular to an orthodontic molar distalization device. Background Art

[0002] Orthodontics covers a wide range, and usually refers to the treatment process of correcting uneven teeth, abnormal tooth shape, and abnormal tooth color through oral technical means. There are many methods of tooth correction, such as resin veneers, porcelain veneers, porcelain teeth, orthodontics, etc. The treatment method should be selected according to the actual situation of the individual's teeth, the type of malocclusion, etc., and then combined with personal requirements. Each method has its own advantages and disadvantages, and different people have their own preferences. It is necessary to communicate directly with the doctor during the examination to determine the plan, which is mainly divided into functional correction and aesthetic correction. Currently in orthodontic clinical diagnosis and treatment, many patients have mesial movement of maxillary molars, resulting in crowding in the anterior or middle section of the dental arch, and the molar relationship is often incomplete distal relationship. In order to adjust the molar occlusion to neutral or provide space for aligning the teeth during orthodontic treatment, it is usually necessary to push the molars that move mesially toward the distal.

[0003] The orthodontic molar pushing and displacing device in the prior art still has some problems during use. First, its elastic component is usually fixedly connected to the entire device. If the elastic component is damaged, the entire displacing device needs to be replaced. Second, there is no adjustment function. As the correction progresses, the angle of the tilted molars will gradually become smaller, and the gap between the molars will become larger, resulting in a decrease in the elasticity of the elastic component. This requires the replacement of elastic parts with greater elasticity to ensure that the molars are stably stressed. The elastic component cannot be removed or adjusted, which still requires the replacement of the entire displacing device, which is not conducive to use. Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing ones on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which cannot achieve the desired effect.

[0030] The distal movement assembly 2 includes an elastic unit 21, which is located between two molar fixing blocks 13, and is used to support the distal movement of the molars;

[0031] The distal movement component 2 further includes a fixing unit 22 . The fixing unit 22 is sleeved on the surface of the molar fixing member 12 . The fixing unit 22 is used to fix the elastic unit 21 .

[0032] As a further definition of the present invention, the elastic unit 21 includes a shell 2101, and positioning blocks 2102 are provided on the front and rear sides of the shell 2101. Positioning grooves 2103 are provided on the top and bottom of the opposite sides of the two positioning blocks 2102. The surface of the positioning block 2102 is fixedly connected to the molar fixing block 13. Push blocks 2104 are provided on the front and rear sides of the inner cavity of the shell 2101, and push rods 2105 are fixedly connected on the top and bottom of the opposite sides of the two push blocks 2104. The side of the push rod 2105 away from the push block 2104 passes through the shell 2101 and extends to the inner cavity of the positioning groove 2103.

[0033] An adjusting block 2106 is provided in the inner cavity of the shell 2101 and on the opposite side of the two push blocks 2104. The opposite sides of the two adjusting blocks 2106 are fixedly connected with a limiting telescopic rod 2107. The side of the limiting telescopic rod 2107 away from the adjusting block 2106 is fixedly connected to the push block 2104, and a spring 2108 is sleeved on the surface of the limiting telescopic rod 2107.

[0034] A screw rod 2111 is movably connected at the top of the inner cavity of the shell 2101 and located between the two adjusting blocks 2106. A screw sleeve 2112 is sleeved on the surface of the screw rod 2111. The bottom of the screw rod 2111 penetrates the bottom of the shell 2101 and is fixedly connected to a rotating block 2113. The front and rear sides of the screw sleeve 2112 are both provided with lifting blocks 2114. The opposite sides of the two lifting blocks 2114 are both provided with sliding rods 2115.

The push block 2104 can push the molars through the cooperation of the push rod 2105 and the positioning block 2102, so that the molars can be driven to move away gradually. When the molars move away, the elasticity of the spring 2108 will become smaller due to the stretching, and the rotating block 2113 can be rotated at this time, and the rotating block 2113 drives the screw 2111 to rotate, and the rotation of the screw 2111 can drive the screw sleeve 2 112 moves upward, and the screw sleeve 2112 can drive the bottom of the adjusting frame 2118 to move upward through the cooperation of the lifting block 2114, the sliding sleeve 2116 and the first mounting block 2117. The other end of the adjusting frame 2118 can drive the two adjusting blocks 2106 to move away from each other through the cooperation of the second mounting block 2119. The adjusting block 2106 can drive the spring 2108 to contract, so that the spring 2108 can be restored to its original state, and the elastic force of the spring 2108 can be adjusted without replacing an elastic component with a larger elastic force, thereby ensuring that the molars are stably stressed.
