Description

Technical Field

[0001] The utility model belongs to the technical field of dental tools, and in particular relates to a handheld molar propeller. Background Art

[0002] Dental problems such as crowded, misaligned or abnormal bite may cause food impaction, gum recession, excessive tooth wear and even temporomandibular joint disorder. Therefore, tooth correction is particularly important. Corrected teeth are easier to clean and can reduce the risk of caries and periodontal disease. After correction, it can also have a significant modifying effect on facial shapes with abnormal jaw development such as convexity and overbite.

[0003] Wearing invisible fixed braces during orthodontic treatment can establish a normal occlusion and avoid the pain of tooth extraction. When wearing fixed braces, the molars need to be moved distally to increase the space for tooth alignment. However, since the shape of fixed braces is fixed and the position of molars is not easily moved, fixed braces are difficult to wear and may even cause tooth damage if forced. Therefore, the extent of molar distalization must be strictly controlled to prevent adverse consequences.

[0004] Chinese patent CN204133621U discloses a molar pusher, including a fixed bottom rod, a sliding rod and a force spring. The fixed bottom rod is composed of a horizontal bottom rod parallel to the sliding rod and left and right inclined rods. An arc-shaped fixed block and an arc-shaped sliding block are respectively provided near the two ends of the horizontal bottom rod; the arc-shaped fixed block and the arc-shaped sliding block are respectively connected to the upper surfaces of the left and right inclined rods to form streamlined curved surfaces; one end of the sliding rod is fixed on the arc-shaped sliding block, and the other end passes through the sliding hole on the upper part of the arc-shaped fixed block; a spherical bolt is provided on the upper surface of the inclined rod near the arc-shaped sliding block, and a traction hole is opened on the arc-shaped sliding block.

[0005] The above patent requires fixed installation on the teeth to achieve molar advancement. Long-term use may cause loosening of tooth roots, gum atrophy, etc. Utility Model Content

[0006] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a handheld molar pusher to move the molars distally when wearing fixed braces, thereby loosening the molars and making the wearing of fixed braces smoother.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] The handheld molar pusher described in the utility model includes a molar slot, a connecting rod is provided on one side of the molar slot, the connecting rod is connected to an angle conversion rod at one end away from the molar slot, the angle conversion rod is connected to a handheld rod, the middle part of the molar slot is a slot body, a slot wall is vertically provided on the slot body, the slot wall is provided on the outside of the slot body, a support point is provided in the middle part of the slot wall away from the end of the slot body, and the outside of the slot wall is vertically connected to the connecting rod.

[0009] in:

[0010] The slot wall is integrally formed in a U-shape and is vertically arranged on the slot body. The slot wall includes supporting walls on both sides and a connecting wall for connecting the supporting walls.

[0011] The width of the slot wall opening is greater than the width of the slot wall connecting wall.

[0012] The connecting rod is connected to the outer side of the connecting wall of the slot wall.

[0013] The support clamping point is arranged at the middle of the top end of the connecting wall of the clamping slot wall.

[0014] The thickness of the slot body at the side away from the slot wall connecting wall is smaller than the thickness of the middle part of the slot body.

[0015] The thickness of the slot wall at a side away from the slot body is smaller than the thickness at the connection between the slot wall and the slot body.

[0016] The hand-held rod is arranged in parallel with the connecting rod.

[0017] The bottom of the hand-held rod is provided with a plurality of hand-held grooves.

[0018] The included angle between the connecting rod and the angle conversion rod is 100-130°.

[0019] The beneficial effects of the utility model are:

[0020] The utility model has a simple structure and is easy to operate. It can realize the movement of molars before wearing fixed braces, which is convenient for wearing fixed braces for teeth correction and improves efficiency. The molar clamping groove in the utility model is arranged in accordance with the shape of the molars, which can facilitate the movement of the molars when in use. Since the molar clamping groove can be well clamped in the molar gap, the molar can be pushed distally by using the lever principle, which can continuously expand the gap between the molars and facilitate the wearing of fixed braces. Due to the arrangement of the angle changing rod, it saves more effort when in use and better pries the molars to move. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5 As shown, the handheld molar pusher described in the utility model includes a molar slot 1, a connecting rod 4 is provided on one side of the molar slot 1, the connecting rod 4 is connected to the angle changing rod 2 at one end away from the molar slot 1, the angle changing rod 2 is connected to the handheld rod 3, the middle part of the molar slot 1 is a slot body 101, a slot wall 102 is vertically provided on the slot body 101, the slot wall 102 is provided on the outside of the slot body 101, a support point 103 is provided in the middle of the slot wall 102 away from the end of the slot body 101, and the outer side of the slot wall 102 is vertically connected to the connecting rod 4.

[0030] The card slot wall 102 is vertically arranged on the card slot body 101 in a U-shape as a whole. The card slot wall 102 includes supporting walls on both sides and a connecting wall for connecting the supporting walls.

[0031] The width of the opening of the slot wall 102 is greater than the width of the connecting wall of the slot wall 102 .
