Embodiment Construction

[0023] The following examples are used to further illustrate the present invention, but are not intended to limit the scope of protection of the present invention.

[0024] Take a rectangular buccal tube with two archwire lumens as an example, such as figure 1 As shown, it is the upper molar buccal tube, and there are two rectangular archwire lumens 1 and 2 in the buccal tube, which are located in a plane parallel to the buccal surface. The angle between the vertical cross section of the archwire lumen and the vertical line of the occlusal surface is the axial inclination γ, the axial inclination γ of the archwire lumen 1 is -5°, and the axial inclination γ of the archwire lumen 2 is - 15°. The traction hook 3 is the position where the apron is hung when the front teeth are pulled backward, and those skilled in the art can judge the buccal tube orientation according to it.

[0025] Such as figure 2 As shown, the archwire lumens 1 and 2 are rectangular in shape, and the ang...

Abstract

Provided is an anchorage preparation buccal tube having at least two arch tubes for receiving correction arch wire, wherein the axis inclination angle of at least one arch tube is a negative value. The lines of said arch tubes or the projections thereof on the buccal surface intersect with each other. The buccal tube can be designed into having a plurality of cross-arranged arch wire tubes, the physician can insert the correction arch wire into arch tube with suitable angle to recline the molar so as to increase anchorage in different stages according to the anchorage value needed for correction.

Description

technical field [0001] The invention relates to an orthodontic device on the posterior teeth of a fixed appliance, in particular to a buccal tube of the posterior teeth. Background technique [0002] At present, the posterior buccal tubes of all fixed oral appliances in the world are single-tube, double-tube or triple-tube designs that are basically parallel to the occlusal plane of the upper and lower teeth. Single tube is used to receive orthodontic arch wire, mainly used for mandibular posterior teeth; there are two types of double tube, the first one is 1 main arch wire plus 1 auxiliary arch wire, the two tubes are parallel to each other; the other is 1 The main arch wire tube is added with an extra-oral arch tube with a larger diameter; the third tube is the first type of the above-mentioned double-tube structure, plus an extra-oral arch tube. The main archwire tube is used to receive the main corrective archwire. Traditionally, the design concept of the buccal canal ...
