Abstract
The utility model provides a towing hook used for orthodontics and belongs to the orthodontics field. The towing hook used for orthodontics comprises a towing rod and a fixed part blocked and sleeved on a tooth surface, wherein one end of the towing hook is equipped with a bent hook; the other end of the towing hook is movably connected with the fixed part. In II-type towing, the towing hook disclosed by the utility model is used, so that eyeteeth do not receive vertically downward component force, rear-lower rotation of an occlusal plane is avoided, and therefore, the towing hook is beneficial to facial contour improvement.
Description
Technical field
This utility model belongs to mouth cavity orthodontic field, is specifically related to the hook for mouth cavity orthodontic.
Background technology
In mouth cavity orthodontic, conventionally need to draw tooth.Wherein, between jaw, the traction of II class is conventional tractive manner.For example, during clinical common iS-One II class is ground one's teeth and closed, conventional Therapeutic Method is exodontia treatment, need to pull on labial teeth far away middle mobile, and upper jaw backteeth anchorage needs protection simultaneously.For the effect obtaining, between Upper Anterior Teeth and lower backteeth, draw.But in the traction of II class, Upper Anterior Teeth can be subject to component vertically downward, and lower backteeth is subject to component vertically upward, thereby causes the rear lower rotation of bite plane, is unfavorable for the improvement of face type.
Summary of the invention
The purpose of this utility model is to provide a kind of hook for mouth cavity orthodontic, in the traction of II class, use this hook, eyetooth can not be subject to component vertically downward, and lower backteeth can not be subject to component vertically upward, avoid the rear lower rotation of bite plane, be conducive to face type and improve.
For a hook for mouth cavity orthodontic, comprise draw bar and for being fastened in the fixed part of dental surface, one end of described draw bar is provided with crotch, the other end is flexibly connected with fixed part.
One end relative with crotch on described draw bar is connected with tubular body, and described tubular body is socketed described fixed part outside.
Described fixed part is a circle not sealing.
Described draw bar outside is provided with the groove for making traction circle maintenance.
Because draw bar of the present utility model is movably connected on fixed part, so draw bar can rotate round fixed part, make crotch up or down.In the traction of II class, fixed part of the present utility model is fastened in to the surface of eyetooth, it is cemented fixed to glue with glue, by under the crotch rotation direction of draw bar, then one end of elastic traction circle is attached on the hook of lower backteeth buccal tube, the other end of this traction circle is placed on to backteeth same level position, draw bar up and down, eyetooth can not be subject to component vertically downward, lower backteeth can not be subject to component vertically upward, only retain horizontal direction strength, can not cause the rear lower rotation of bite plane, be conducive to the improvement of face type.On the feed time, for fear of disturbing its functional movement, the crotch of draw bar is spun up, then eyetooth and upper backteeth are drawn by draw bar of the present utility model.The life that so neither affects patient obtains good clinical effectiveness simultaneously.

Detailed description of the invention
This utility model is for the hook of mouth cavity orthodontic, comprises draw bar 3 and for being fastened in the fixed part 2 of dental surface, one end of draw bar 3 is provided with crotch 4, the other end is flexibly connected with fixed part 2.
On draw bar, one end relative with crotch is connected with tubular body 1, and tubular body 1 is socketed on fixed part 2 outsides.
Fixed part 2 is preferably a circle not sealing.
Draw bar 3 outsides are provided with the groove for making traction circle maintenance.
Because draw bar of the present utility model is movably connected on fixed part, so draw bar can rotate round fixed part, make crotch up or down.In the traction of II class, fixed part of the present utility model is bonded in to the surface (as shown in Figure 2) of eyetooth, it is cemented fixed to glue with glue, by under the crotch rotation direction of draw bar, then one end of an elastic traction circle is attached on the hook of lower backteeth buccal tube, the other end of this traction circle is placed on to backteeth same level position, draw bar up and down, eyetooth can not be subject to component vertically downward, lower backteeth can not be subject to component vertically upward, only retain horizontal direction strength, can not cause the rear lower rotation of bite plane, be conducive to the improvement of face type.On the feed time (as shown in Figure 3), for fear of the functional movement of disturbing tooth, the crotch of draw bar is spun up, then eyetooth and upper backteeth are drawn by draw bar of the present utility model.The life that so neither affects patient obtains good clinical effectiveness simultaneously.
