Abstract
The utility model provides an orthodontic bracket with a groove with a ridge, which is characterized in that two sides of a bottom plate of the bracket are respectively provided with a bracket wing, the bottom plate between the two bracket wings is a positioning groove, the middle part of which is provided with an upward ridge; and the top of the ridge is arc-shaped or sharp-angle-shaped. The groove adopts a ridge-shaped bottom, thus leading the groove to generate greater friction than a horizontal groove design when being contacted with an arch wire by positive pressure; and the orthodontic bracket achieves the function of adjusting the friction more effectively, and further controlling the movement of teeth more effectively.
Description
Technical field
This utility model is the improvement to traditional orthodontic bracket structure, especially discloses the orthodontic bracket that a kind of groove has ridge, belongs to orthodontics apparatus technical field.
Background technology:
At present, in the dental orthodontic technical field, form is the horizontal bottom design at the bottom of the groove of four wing brackets that generally use and six wing brackets both at home and abroad, and the bracket structure that at the bottom of the groove is horizontal plane is after ligation, exist the indentation resistance to cause the excessive shortcoming of frictional force, be unfavorable for moving of tooth.
Summary of the invention
This utility model discloses the orthodontic bracket that a kind of groove has ridge, has solved traditional orthodontic bracket indentation resistance and has caused the excessive shortcoming of frictional force.
Technical solution of the present utility model is as follows:
The both sides of bracket supporting plate are provided with the bracket wing, and the base plate between the two bracket wings is the location groove, and it is characterized in that: the middle part of groove is provided with ridge upwards, and the top shape of ridge is arc or pointed shape.
Adopt ridge shape at the bottom of the bracket groove, and the height of wing cell wall in the middle of the corresponding increase bracket, make it, when middle wing ligation, can realize the low-frictional force of arch wire and groove greater than the arch wire height; And when the flank ligation, because the ridge shape structure of groove is normal pressure with arch wire and contacts, six wing brackets of more horizontal groove produce bigger frictional force, have reached the function of more effective control frictional force size, thereby have reached the purpose that more effective control tooth moves.
Good effect of the present utility model is: adopt ridge shape at the bottom of the groove, make it with arch wire more horizontal groove design when normal pressure contacts bigger frictional force be arranged; Reached the function of more effective adjusting frictional force size.Function with scalable frictional force size, so can more effective control tooth move.
Description of drawings
Fig. 1 is the arcuate structure schematic diagram for ridge top shape of the present utility model;
Fig. 2 is the pointed shape structure principle chart for ridge top shape of the present utility model.
Among the figure, 1, the bracket supporting plate; 2, the bracket wing; 3, location groove; 4, ridge.
The specific embodiment
According to shown in Figure 1, this utility model is made of bracket supporting plate 1 and two bracket wings 2, and the base plate between the two bracket wings 2 is location groove 3, it is characterized in that: the middle part of location groove 3 is provided with ridge 4 upwards, and the top shape of ridge 4 is an arc; Also the top design of ridge 4 can be become pointed shape (referring to Fig. 2).
Claims (2)
1. a groove has the orthodontic bracket of ridge, and the both sides of bracket supporting plate are provided with the bracket wing, and the base plate between the two bracket wings is the location groove, it is characterized in that: the middle part of location groove is provided with ridge upwards.
2. orthodontic bracket according to claim 1 is characterized in that: the top shape of ridge is arc or pointed shape.
