Problems solved by technology

[0006] The purpose of the present invention is to provide a maxillary occlusal pad type molar remoter for the dentition period, which is suitable for the dentition period, high-efficiency and distal overall movement of the maxillary first molars, and solves the problem of movable appliances existing in the prior art due to retention. and insufficient anchorage are not suitable for the replacement dentition stage with fewer teeth, delaying the timing of treatment, and limiting the treatment effect, etc.

Embodiment 1

[0029] A kind of maxillary occlusal pad type molar remote mover in the replacement dentition period, such as figure 1 , including a fixed fulcrum assembly 1 and a distal displacement assembly 2 for moving the first molar 3 to be displaced, such as figure 2 and image 3 , the fixed fulcrum assembly 1 includes the base 11 for the fulcrum, the interproximal hook one 12 for the fulcrum, the interproximal hook two 13 for the fulcrum and the hyperbolic labial bow 14 for the fulcrum, as Figure 4 One side of the hyperbolic labial arch 14 for the fulcrum is embedded in the base 11 for the fulcrum, and the other side of the hyperbolic labial arch 14 for the fulcrum is set on the labial side of the dentition, and the fulcrum is embedded in the base 11 to be removed. For all the dentition except the first molar 3, interproximal hook 12 for fulcrum and interproximal hook 2 13 for fulcrum are respectively set on both sides of base 11 for fulcrum, and interproximal hook 12 for fulcrum, in...

Embodiment 2

[0043] The structure of embodiment two is basically the same as that of embodiment one, and the difference between embodiment two and embodiment one is that: as Figure 5 , the distal displacement assembly 2 includes a left distal displacement assembly 2 for displacing the left first molar 3 to be displaced and a right distal displacement assembly 2 for displacing the right first molar 3 to be displaced Displacement component 2, the base 22 for displacement of the left distal displacement component 2 embeds one side of the middle auger 25 for displacement, and the other side of the middle auger 25 for displacement is embedded in the right side The base 22 for displacement of the distal displacement component 2 and the intermediate helical expander 25 for displacement are arranged at the midpalatal suture.

[0044] Unlike Embodiment 1, which is applicable to the distal displacement of the first molar 3 to be displaced on one side, in Embodiment 2, through the left distal displa...

Abstract

The invention provides a maxillary occlusal pad-type molar remoter during the dentition period, which includes a fixed fulcrum assembly and a distal displacement assembly for moving the first molar to be displaced. The fixed fulcrum assembly includes a fulcrum base, a fulcrum Interproximal hook 1, interproximal hook 2 for fulcrum, and hyperbolic labial arch for fulcrum; Distal displacement components include arrow clips for displacement, base for displacement, buccal helical expander for displacement, and palate for displacement Lateral screw expander; this kind of maxillary occlusal cushion type molar remote mover in the replacement dentition period can effectively move the upper first molar distally. Place the spiral expander on the center plane of the resistance of the first molar to be displaced, and gradually increase the force to complete the correction of the overall distal movement of the first molar to be displaced; through the fulcrum, the base is firmly bonded to the gum to provide maximum support resistance to reduce unwanted movement of other teeth.

Description

technical field [0001] The invention relates to a maxillary occlusal pad type molar remoter in the dentition period. Background technique [0002] The eruption and replacement process of teeth is promoted by many factors. During the replacement period, the caries or premature loss of the second deciduous molars often lead to the mesial movement of the first molars, resulting in the impaction of the second premolars and affecting the normal replacement of teeth. Early intervention is needed to move the mesially moved first molars far away to promote the normal eruption of permanent teeth and avoid the occurrence of complex malocclusion. In the replacement period, there are relatively few teeth that can provide anchorage, and the retention of the appliance is insufficient, and the mesially moved first molars cannot effectively move to the normal position. Therefore, it is urgent to design an orthodontic appliance that has relatively less requirements for anchorage teeth, les...
