Description

Technical Field

[0001] The utility model relates to the field of maxillary impacted front teeth traction, in particular to a novel traction device for maxillary impacted front teeth. Background Art

[0002] Maxillary impacted teeth refer to teeth that fail to grow vertically normally in the alveolar bone. This may cause the teeth to not appear properly in the mouth, but remain in the alveolar bone, usually due to insufficient space or obstruction by other teeth. In early childhood orthodontic treatment, 7-9 year old children often have maxillary incisors that are impacted horizontally and labially. If not treated in time, maxillary impacted teeth may cause oral discomfort, dental crowding, bite problems, and tooth displacement.

[0003] At present, a traction device for maxillary impacted teeth is usually used to pull the maxillary impacted incisors at an early stage to prevent the occurrence of crooked root teeth in the maxilla. However, when the existing traction device for maxillary impacted teeth is used, the traction length of the impacted crown is insufficient and the traction direction is not good, which easily increases the probability of gingival recession. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art that the traction length of the impacted crown is insufficient and the traction direction is not good, which easily increases the probability of gum recession, and proposes a new traction device for maxillary impacted front teeth.

[0028] Reference Figure 1-Figure 8 A novel traction device for maxillary impacted anterior teeth comprises a first traction chain 1 and a second traction chain 2, and also comprises: a bracket 3, fixedly connected to the first traction chain 1 and the second traction chain 2; a first tooth fixing sleeve 4, fixedly connected to the bottom of the first traction chain 1 and the second traction chain 2, the bottom of the first tooth fixing sleeve 4 is rotatably connected with the second tooth fixing sleeve 5, and the surface of the second tooth fixing sleeve 5 is fixedly connected with the first arch wire 6 and the second arch wire 7; a fluid resin pad 8, fixedly connected between the first arch wire 6 and the second arch wire 7; a ligature wire 9, arranged between the first traction chain 1 and the second traction chain 2, the ligature wire 9 is fixedly connected with the second arch wire 7, the ligature wire 9 is arranged in an arc shape, and can be prevented from falling off by the fluid resin pad 8. The traction device solves the problems of insufficient traction length and poor traction direction when traction is performed horizontally toward the crown of the impacted tooth, and reduces the probability of excessive rotation and movement of the impacted tooth, thin lip bone plate, and gingival recession.

[0029] The brackets 3 are provided in multiple groups and are arranged in an array along the first traction chain 1 and the second traction chain 2. The positions and directions of the teeth can be changed through the multiple groups of brackets 3 so that the teeth are arranged neatly.

[0030] A mounting groove is provided on the bottom surface of one side of the first tooth fixing sleeve 4 away from the first traction chain 1, and a limit plate 10 is hinged on the inner walls on both sides of the mounting groove of the first tooth fixing sleeve 4. A torsion spring 11 is fixedly connected to the top of the limit plate 10, which facilitates the limit plate 10 to automatically reset downward after rotation.

[0031] One end of the torsion spring 11 away from the limit plate 10 is fixedly connected to the inner wall of the first tooth fixing sleeve 4, and fixing plates 12 are fixedly connected to the inner walls on both sides of the first tooth fixing sleeve 4 near the bottom of the limit plate 10. The fixing plates 12 can support the limit plate 10 and prevent the limit plate 10 from rotating downward.

[0032] A groove is provided on the top surface of the second tooth fixing sleeve 5, and a rotating rod 13 is rotatably connected in the groove of the second tooth fixing sleeve 5. A strip plate 14 is fixedly connected to the top of the rotating rod 13, and clamping plates 15 are fixedly connected to the top two sides of the strip plate 14. When the first arch wire 6 is pulled upward, the rotating rod 13 in the groove of the second tooth fixing sleeve 5 can be driven upward, and the strip plate 14 and the clamping plates 15 on both sides can be driven into the installation groove of the first tooth fixing sleeve 4. The clamping plate 15 compresses the torsion spring 11 by squeezing the limiting plate 10, so that the clamping plate 15 slides through and is clamped with the limiting plate 10, thereby completing the fixation between the first tooth fixing sleeve 4 and the second tooth fixing sleeve 5.

[0033] A gear 16 penetrates the bottom surface of the rotating rod 13 and is fixedly connected to the rotating rod 13. A sliding groove is provided on the inner wall of the groove of the second tooth fixing sleeve 5. A rack 17 is slidably connected in the sliding groove of the second tooth fixing sleeve 5, and the rack 17 is meshed with the gear 16. When it is necessary to disassemble the first tooth fixing sleeve 4 and the second tooth fixing sleeve 5, the rack 17 in the sliding groove on the outer wall of the second tooth fixing sleeve 5 can be pushed with the help of a tool to mesh with the gear 16, thereby driving the rotating rod 13 to rotate. The rotation of the rotating rod 13 drives the top strip plate 14 and the clamping plate 15 to rotate and disengage from the limiting plate 10, thereby releasing the limit, so that the first tooth fixing sleeve 4 and the second tooth fixing sleeve 5 can be disengaged.

[0034] A reset spring 18 is fixedly connected to the surface of one side of the rack 17 close to the groove of the second tooth fixing sleeve 5, and the end of the reset spring 18 away from the rack 17 is fixedly connected to the inner wall of the groove of the second tooth fixing sleeve 5. When the rack 17 slides, the reset spring 18 will be compressed, and the reset spring 18 can automatically reset the rack 17.

[0035] A buffer spring 19 is fixedly connected to the back surface of the fluid resin pad 8 , and a buffer pad 20 is fixedly connected to one end of the buffer spring 19 away from the fluid resin pad 8 . The buffer spring 19 and the buffer pad 20 can play a buffering role.

[0036] In the utility model, when the traction device is used, the first traction chain 1 and the second traction chain 2 are fixed to the open large curve of the looped curve of the traction device through the ligature wire 9, and are fixed with the fluid resin pad 8 to prevent falling off. When the fluid resin pad 8 is fixed, the second tooth fixing sleeve 5 at the bottom of both sides of the traction device is pulled by the first arch wire 6 and the second arch wire 7 to rotate and drive the strip plate 14 on the rotating rod 13 in its groove. The strip plate 14 drives the clamping plate 15 to enter the first tooth fixing sleeve 4 and contact with the limiting plate 10, so that the limiting plate 10 compresses the torsion spring 11 and rotates upward, so that the clamping plate 15 and the top surface of the limiting plate 10 The tooth fixing sleeve 4 is stuck to fix the first tooth fixing sleeve 4 and the second tooth fixing sleeve 5, thereby fixing the teeth. When disassembly is required, the rack 17 in the slide groove of the outer wall of the second tooth fixing sleeve 5 is entered by means of a tool, and slides into the slide groove of the second tooth fixing sleeve 5 to engage with the gear 16, so that the rotating rod 13 drives the top strip plate 14 and the card plate 15 to rotate, so that the card plate 15 and the limit plate 10 are rotated to the space between the two limit plates 10, thereby disengaging from the limit plate 10, so that the first tooth fixing sleeve 4 is disengaged from the second tooth fixing sleeve 5, and the rack 17 is automatically reset under the action of the reset spring 18.
