Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to the technical field of tooth orthodontics, in particular to an active precise orthodontic force multiplier. Background Art

[0002] There are three main types of dental corrections: traditional wire braces (correctors), lingual braces (correctors), and invisible braces (correctors). These correctors (braces) require doctors to adjust and apply force once after being worn for a period of time to allow the teeth to continue moving. They are all classified as intermittent forces; spring traction is classified as continuous force, but traditional continuous force must take into account the influence of torque, support and other component forces, and the magnitude of intermittent force and continuous force must be measured by professional measuring tools, which is more troublesome.

[0003] Currently, braces are mainly installed in the center of the teeth to form a straight line. Since the dental arch is not a straight line from front to back (there are compensation curves and Spee curves), one month after installation in the center of the teeth, the bite of the large teeth behind the braces will appear open-jawed, requiring adjustment at the end of orthodontic treatment. The adjustment takes a long time, and force cannot be applied continuously after the adjustment. For example, the patent with publication number CN 220124846 U discloses an adjustable bracketless invisible brace accessory with a retractor, comprising: a fixing seat, a retractor, the retractor is connected by a flexible end and a hard hook, the end of the flexible end away from the hard hook can pass through a through hole and bend, and in actual use, the height of the hard hook can be adjusted according to the actual size of the dentition to make it consistent with the height of the support pin or other traction devices, thereby ensuring that the overall movement of the teeth can move in the expected direction or angle to achieve the correction goal; a movable structural design is adopted between the retractor and the fixing seat, and in clinical practice, the hook can be rotated according to the size and method of traction force to be installed in a fixed mesial or distal direction; although it can be adjusted, there are problems such as a long adjustment time and inability to continue to apply force after adjustment, and there is also a defect that the force value must be measured by professional measuring tools, which makes adjustment troublesome.

[0004] At present, a new force-adding device is urgently needed to solve the above problems. Summary of the invention

[0005] The utility model aims to provide an active precise orthodontic force adder, which can continuously add force, and the size of the force, the control of the supporting teeth, and the fine adjustment of the vertical occlusion of the posterior teeth can all be accurately visually measured, thereby reducing the usage rate of the supporting nails.

[0006] The technical concept of the utility model is as follows: the movement of the traction hook on the traction hook bracket is spring traction, and the traction hook and the traction hook bracket are also elastically connected to the connecting base plate in the vertical direction, not rigidly connected; a ruler is provided on the traction hook bracket, and the traction force value of the traction hook can be accurately visually measured through the force value scale on the ruler.

[0007] The technical solutions of the utility model are divided into two kinds, one is applicable to invisible braces, and the other is applicable to lingual braces and wire braces.

[0009] The vertical support arm of the towing hook support passes through the first through groove, and a first stopper is provided at the upper end of the vertical support arm of the towing hook support. An upper compression spring or a lower compression spring or an upper compression spring and a lower compression spring are mounted on the vertical support arm. The upper compression spring and the lower compression spring realize the elastic connection between the vertical support arm and the connecting base plate.

[0010] Furthermore, the inclined surface of the inclined boss is inclined upward by 35-50° in the vertical direction, which facilitates the adjustment of the position of the connecting body relative to the invisible braces from bottom to top during installation.

[0011] Furthermore, the inclined surface of the inclined boss is inclined downward by 35-50 degrees in the vertical direction, which facilitates the adjustment of the position of the connecting body relative to the invisible braces from top to bottom during installation.

[0012] Technical solution applicable to lingual braces or traditional wire braces: an active precise orthodontic force booster, including a connecting base plate and a traction hook bracket that can be attached to the surface of the teeth, characterized in that:

[0013] The inner surface of the connecting bottom plate is a bonding surface, and a boss is provided on the outer surface of the connecting bottom plate, and a through hole cavity is provided on the boss. A protruding first connecting plate is provided at the bottom position of the connecting bottom plate, and a first through groove is provided on the protruding first connecting plate; a vertical bracket arm is provided at one end of the traction hook bracket, and a protruding second connecting plate is provided at the other end of the traction hook bracket, and a second through groove is provided on the protruding second connecting plate, and a scale is provided on the front of the traction hook bracket; the traction hook passes through the second through groove, and a second stopper is provided at the tail of the traction hook, and a horizontal compression spring is sleeved on the traction hook, and both ends of the horizontal compression spring are limited by the second stopper and the protruding second connecting plate;

[0017] Furthermore, for the above two solutions, the first stopper is threadedly connected to the vertical support arm; the second stopper is threadedly connected to the towing hook; this arrangement is convenient for assembly.

[0018] Furthermore, for the above two schemes, the inner surface of the connecting base plate is a mesh pattern surface. When actual tooth correction is required to apply force, the base is adhered to the tooth surface through adhesive. The mesh pattern makes the adhesion more firm. Once adhered, it becomes one with the molar surface.

[0019] The beneficial effects of the utility model are as follows: different connecting base plates are adopted, and the other structures are universal and the connecting base plates are replaceable; the connecting base plates provided with the bevel angle boss are applicable to invisible braces (correctors), and the elevation or depression efficiency is different due to the different orientations of the bevel angles; the connecting base plates provided with the through-hole cavity are applicable to lingual braces and wire braces, and the purpose is to insert the main arch wire of the lingual braces or wire braces; a horizontal spring is installed, and the horizontal spring is compressed to generate a reaction force, so that a continuous traction force is obtained, and at the same time, the vertical spring has a self-adjusting force, that is, synchronous two-dimensional control can be performed; and the traction force is visualized, and there is no need to use a dynamometer to measure it like in the traditional way; and the traction hook bracket is close to the vestibule groove, so that the root control in the support and tooth movement can be achieved in one step; when performing tooth correction, whether it is invisible correction, traditional corrector or lingual braces correction, when the base is pasted on the molar surface, the traction hook is pulled, and a continuous traction force can be generated, and at the same time, the support and the root control can be performed at the same time, which greatly reduces the usage rate of the support nails.
