Technical Field

The invention relates to the technical field of tooth sockets, in particular to a bracket-free invisible appliance accessory.

Background

The traditional bracket-free invisible appliance is characterized in that a tooth jaw model obtained by a tomography technology is used for inputting three-dimensional data of the model, three-dimensional reconstruction of the model is carried out, and the reconstructed digital model can accurately obtain data of teeth, dental arches, basic bones and the like through a computer. On the basis, each step of clinical correction design and tooth correction can be simulated by combining a three-dimensional image processing 3D printing technology. A resin model for each step of orthodontics may be obtained by 3D printing techniques. The transparent invisible orthosis of each step is pressed on the molded resin mold. Thus, the whole bracket-free invisible appliance can correct the teeth under the condition that the bracket-free invisible appliance is not easy to be found by people. However, after clinical application, the problems of torque, anchorage and the like exist in all kinds of bracket-free invisible orthotics at present due to natural reasons, the effect is poor, and the speed is too slow. It is difficult to achieve the expectation.

In view of the above, the present invention provides a new technical solution to solve the above problems.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides a bracket-free invisible appliance accessory, which has the following specific scheme:

comprises more than one fixed accessory and an active assistor component; the fixing accessory is used for being stuck and installed on the appliance body and further fixed on the labial side or the lingual side of the teeth; the active force booster group comprises a base and a force boosting main body connected and installed with the base, and the force boosting main body comprises a sleeve, a traction rod and a force boosting spring, wherein the traction rod extends and retracts in the sleeve;

the stress spring is used for providing a variable elastic force for the traction rod;

when the active assistor component is used, the active assistor component is arranged on the tooth buccal side surface or the tongue side surface of the rear tooth section, and the extending end of the traction rod is connected with the fixed accessory through a connecting rod.

Preferably, a pull buckle is arranged at one end of the traction rod in the sleeve, and a slot for the pull buckle to extend out is formed in the sleeve; the spring is sleeved on the sleeve, one end of the spring is fixed and limited, and the other end of the spring is limited by the pull buckle.

Preferably, the spring force applied by the forcing spring to the drawbar is in a backward direction, i.e. in a direction opposite to the direction in which the drawbar extends.

Preferably, the spring force applied by the forcing spring to the drawbar is forward, i.e. in the same direction as the direction in which the drawbar extends.

More preferably, the stress application spring is a pressure spring and is arranged at the rear end of the pull buckle, namely in the direction departing from the extension end of the traction rod;

preferably, the active assistor assembly further comprises movable assemblies in one-to-one correspondence with the fixed accessories, the movable assemblies are movably connected with the fixed accessories, and the traction rods on the active assistor assembly are respectively connected with the movable assemblies through connecting rods so as to be connected with the fixed accessories.

Preferably, the position, close to the gum, of the fixed accessory is provided with an oval quick connector groove accessory, the movable assembly comprises an oval cylindrical connector and a swing rod, the oval cylindrical connector corresponds to the oval quick connector concave accessory, and the movable assembly is horizontally inserted into the oval quick connector groove and is connected with the fixed accessory in a rotating mode.

Preferably, the sleeve is provided with corresponding force value scales.

Preferably, the boosting main body and the base are connected and installed in a pluggable mode through a buckle type structure.

Preferably, two 1/4 spherical convex structures are also arranged on the base.

The bracket-free invisible appliance accessory has the following beneficial effects:

1. even if a user does not wear the transparent pressing die correction device, the directional correction force is generated by driving the spring through the force application main body traction rod; the user does not need to wear the transparent appliance to be attached to the teeth to carry out elastic correction; the active assistor component can easily control the anchorage;

2. the structure is simple and reliable, various bracket-free invisible orthotics can be matched, and the orthotics can generate high-efficiency orthotics force without depending on the orthotics force generated by the traditional invisible orthotics accessory, so that better help can be provided for the compliance of patients; meanwhile, the selection requirement degree of the pressing sheet is not high, so that the use cost can be reduced;

3. in the preferred scheme, the correction force is easy and visible through setting force value scales;

4. in the preferred scheme, different modes can be used for traction at the same time through the application of the movable assembly, so that the flexibility is stronger, and the tooth torque is easier to control;

5. in a preferable scheme, the force application main body is adhered to the buccal side or the lingual side of the back teeth through the base, is highly positioned at the vestibular sulcus of the back teeth and is close to the impedance center of the teeth, so that the torque can be better controlled, when the force application main body performs force application traction, the built-in traction rod extends out, the force arm is lengthened, and one tooth can be easily controlled;

6. in another preferred scheme, the stress application spring is arranged at the rear end of the draw buckle on the draw bar, the stress application effect is changed into the backward pushing of the molar, and the backward pushing of the molar is close to the impedance center because the stress application main body is positioned at the position of the vestibular sulcus of the posterior teeth. Such a pushing molar is forced rearwardly directly at the center of the impedance and the pushing molar will be very upright rearwardly.
