Detailed Description

The utility model has the functions of a traction piece and a tubular piece, and can more flexibly meet the clinical requirements of orthodontics. The orthodontic function provided by the utility model is described below by way of specific examples in order to better illustrate the content of the utility model, but the implementation method described does not limit the protective scope of the utility model.

Figure 1 schematically illustrates orthodontic functionality in one embodiment of the present application.

The functional part comprises a body part (1), an inner pipe (2) and a traction part (3).

The body part (1) is hexahedral in outline and comprises a bottom surface (4), a cavity surface (5) and 4 side surfaces. The length is 2-7 mm, the width is 2-5 mm, and the height is 2-5 mm. The functional piece is fixed on the surface of the shell-shaped appliance or the surface of the tooth through the bottom surface, and the bottom surface can be glued on the mounting surface by using glue for mounting and fixing.

The inner tube (2) is positioned in the body part (1) and penetrates through the body part, is a hollow tube cavity, is in a hollow tube cavity shape, has an unlimited cross section shape, can be circular or square, has a diameter of less than 1.2mm when being a circular tube, and has a side length of less than 1.2mm when being a square tube, and is used for inserting force applying devices such as an orthodontic arch wire, an oral external arch, Forsus, an inter-jaw push-pull rod (spring), a traction hook and the like to provide an orthodontic force or an orthopedic force.

Traction portion (3) are located this somatic part one end, also can be located both ends, for the oral cavity lateral part behind the grooving of this somatic part between bottom surface (4) and oral cavity face (5), the groove degree of depth is below 2mm, provide the traction of first direction, traction portion (3) can hang the piece of pulling (for example rubber band, the extension spring), provide traction force, the inboard perpendicular to bottom surface direction in traction portion bottom can be a small amount of (6) of falling concave, the degree of depth of falling concave is below 1.5mm, in order to do benefit to the piece of pulling and bring the slippage not, traction portion thickness is 0.5 ~ 2mm, in order to resist the traction force of certain dynamics.

Figure 2 schematically illustrates a bottom surface of the orthodontic function body portion of figure 1.

The bottom surface (4) may be square, rectangular, circular, oval or irregular, may be flat or curved (e.g., a curved surface conforming to the shape of a tooth may increase the fit of the bottom surface when it is mounted on the surface of a tooth or shell appliance), may be smooth or rough (e.g., a grid or mesh may be applied to the bottom surface to increase the adhesive area between the bottom surface and the gel).
