Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a sliding space maintainer. Background Art

[0002] The correct position of teeth in the dental arch is the result of the combined effect of many factors. If these factors are out of balance, the close contact relationship with the adjacent teeth will change and tooth misalignment will occur. The premature loss of deciduous teeth may affect the normal eruption of the successor permanent teeth and cause the permanent teeth to be malaligned. The degree to which the permanent dentition is affected is affected by the child's age when the deciduous teeth are lost, the stage of the dentition, the position and number of the missing deciduous teeth, etc. After the premature loss of deciduous canines or molars, the chance of permanent dentition malocclusion is 3 to 4 times higher than those without premature loss of deciduous teeth. Therefore, it is crucial to actively treat deciduous teeth and remove the various factors that cause premature tooth loss in children. After a child loses teeth prematurely, in order to prevent the adjacent teeth from tilting toward the missing space and the opposing teeth from elongating, a space maintainer can be designed to maintain the mesiodistal and vertical spaces of the lost teeth, thereby promoting the normal eruption of the successor permanent teeth. The results of numerous studies have shown that the use of space maintainers can effectively prevent the loss of dentition space and reduce malocclusion. The occurrence of deformities.

[0003] A space maintainer is an oral device that maintains the space between prematurely lost teeth to ensure arch length. This device facilitates the establishment of a normal occlusal relationship without affecting the child's normal growth and development. Currently, traditional removable space maintainers, also known as pediatric removable partial dentures, are transitional restorations typically consisting of a base, retainers, and artificial teeth (dentures or artificial teeth). These devices maintain the space between prematurely lost teeth while maximally restoring the child's chewing function.

[0004] However, the inventors of the present application have found through clinical use research that although traditional removable space maintainers can maintain the mesiodistal space and vertical space of children's prematurely lost teeth, and can also restore the chewing function to a certain extent for children who have lost multiple deciduous molars prematurely, they only consider the mesiodistal and vertical directions, and do not consider the horizontal direction. However, as the age of the children increases, the traditional removable space maintainers will restrict the horizontal growth and development of the children's mandibular dentition, alveolar bone, and jaw, or in other words, will restrict the growth of the horizontal width of the children's mandibular dentition, alveolar bone, and jaw, and therefore there is an urgent need to make improvements in this regard. Utility Model Content

[0005] In view of the technical problem that existing removable space maintainers only consider the mesiodistal and vertical directions but not the lateral directions, however, as the child ages, the traditional removable space maintainers will restrict the lateral growth and development of the child's mandibular dentition, alveolar bone and jaw, or in other words, will restrict the growth of the lateral width of the child's mandibular dentition, alveolar bone and jaw, the present utility model provides a sliding space maintainer.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The tooth of the present invention is connected with the tooth of the present invention, and the tooth of the present invention is connected with the tooth of the present invention.

Since one end of the left slider is embedded in the left resin base and one end of the right slider is embedded in the right resin base, the sliding rod is slidably connected in the left sliding hole of the left slider and the right sliding hole of the right slider. Therefore, as the age of the child increases, the left slider and the right slider can slide freely laterally (left and right) along the sliding rod, or passively slide, thereby not affecting the lateral growth and development of the child's mandibular dentition, alveolar bone, and jaw, or not restricting the growth of the lateral width of the child's mandibular dentition, alveolar bone, and jaw, thereby achieving the maintenance of the mesiodistal (sagittal) space, vertical space, and lateral space. The sliding space maintainer has a simple structure, is quick and easy to install, is comfortable for children to wear, and performs well in clinical treatment.

[0009] Furthermore, the left slider is provided with two left sliding holes extending transversely therethrough, and the right slider is provided with two right sliding holes extending transversely therethrough, and a sliding rod is slidably connected in each pair of the left and right sliding holes.

[0010] Furthermore, a left retaining hole is provided between the two left sliding holes of the left slider near one end of the right slider, and a right retaining hole is provided between the two right sliding holes of the right slider near one end of the left slider, and the right retaining hole is provided between the two right sliding holes of the right slider near one end of the left slider, and the right retaining hole is provided between the two right sliding holes of the right slider.

[0021] Compared with the prior art, the sliding space maintainer provided by the utility model is first placed on the lingual side of the child during treatment, and then the left retainer and the right retainer are fixedly connected to the left and right molars of the child respectively, and the artificial tooth is placed in the missing deciduous tooth gap of the child that is adapted thereto, and one end of the left resin base and the right resin base is located on the lingual side of the child's anterior teeth. Since one end of the left slider is embedded in the left resin base and one end of the right slider is embedded in the right resin base, the sliding rod is slidably connected in the left sliding hole of the left slider and the right sliding hole of the right slider. Therefore, as the age of the child increases, the left slider and the right slider can slide freely laterally (left and right) along the sliding rod, or passively slide, thereby not affecting the lateral growth and development of the child's mandibular dentition, alveolar bone, and jaw, or not restricting the growth of the lateral width of the child's mandibular dentition, alveolar bone, and jaw, thereby achieving the maintenance of the mesiodistal (sagittal) space, vertical space, and lateral space. The sliding space maintainer has a simple structure, is quick and easy to install, is comfortable for children to wear, and performs well in clinical treatment.

[0022] As a specific example, please refer to Figures 1 to 3 As shown, the left slider 61 is provided with two left sliding holes 63 extending horizontally therethrough, and the right slider 62 is provided with two right sliding holes extending horizontally therethrough, and each pair of the left sliding holes 63 and the right sliding holes is slidably connected with a sliding rod 64, thereby better ensuring that the left slider 61 and the right slider 62 can slide freely and stably along the sliding rod 64 horizontally without flipping.

[0023] As a specific example, please refer to Figure 1 and Figure 2 As shown, a left retaining hole 66 is provided between the two left sliding holes 63 of the left slider 61 near one end of the right slider 62, extending through the upper and lower surfaces of the left slider 61. A right retaining hole 67 is provided between the two right sliding holes of the right slider 62 near one end of the left slider 61, extending through the upper and lower surfaces of the right slider 62. As a result, when the left slider 61 is embedded in the left resin base 1 and the right slider 62 is embedded in the right resin base 2, the resin base material can enter the left retaining hole 66 and the right retaining hole 67, thereby strengthening the secure connection between the left and right sliders 61, 62 and the resin base. It should also be noted that in order to ensure the free sliding fit between the left and right sliders 61, 62 and the slide rod 64, no resin base material can enter and block the left sliding hole 63, the right sliding hole, the left groove 65, and the right groove.

[0024] As a specific example, please refer to Figure 1As shown, the sliding gap d between the left slider 61 and the right slider 62 is 3 to 5 mm, so that the sliding space maintainer provided by the present invention can meet the growth needs of the lateral width of the mandibular dentition, alveolar bone, and jaw of children, thereby avoiding the restriction on the lateral growth and development of the mandibular dentition, alveolar bone, and jaw of children.
