Description

A dental appliance for simultaneously lowering and retracting anterior teeth

Technical Field

The utility model belongs to the field of oral orthodontics, and in particular relates to a dental orthodontic appliance capable of simultaneously depressing and retracting front teeth.

Background Art

Generally, patients with protruding teeth and deep overbite will face the problem of lip tilting of teeth when lowering the lower front teeth. In clinical practice, the lower front teeth are usually lowered first, and the lip tilting is ignored. The lower front teeth are then retracted later. In fact, the teeth move back and forth, which aggravates the absorption of alveolar bone and tooth root and prolongs the treatment time. The previous multi-purpose bows were made of corrective wire (usually the thickest is 0.019*0.025 inches). The wire is thinner, and especially cannot provide the force to retract the lower front teeth, resulting in the lip tilting of the front teeth when it is lowered.

Utility Model Content

In order to solve the above problems, the utility model adopts the following technical solutions:

A dental orthodontic appliance for simultaneously lowering and retracting front teeth comprises a main arch wire, which is sleeved on a bracket groove of a patient's dentition, and further comprises:

The auxiliary arch is sleeved on the gingival margin of the patient's bracket and is ligated and fixed with the main arch wire. The auxiliary arch is provided with a plurality of force rings, which are used to depress the lower front teeth.

Furthermore, two force rings are provided, and the two force rings are respectively located below the mesial part of the first bicuspids on both sides.

Furthermore, a rubber chain is provided at the cutting edge of the anterior bracket between the two force rings, and a first end of the rubber chain is connected to one of the force rings, and a second end of the rubber chain is connected to the other force ring.

Furthermore, the auxiliary bow is formed by bending 0.7 mm stainless steel wire.

Furthermore, auxiliary bow fixing parts are provided at both ends of the auxiliary bow.

Furthermore, it also includes an anchorage nail, which is arranged at the position of the posterior teeth, and the auxiliary arch, the main arch wire and the anchorage nail are fixed by ligating with a fixing wire.

Beneficial effects of the utility model:

The utility model is mainly used for lowering and retracting the lower front teeth and can also be used for the maxillary teeth. Through the force ring arranged on the auxiliary arch and the rubber chain interactively pulling the front teeth, the teeth can be more easily moved backwards at the same time when being lowered, thereby improving the treatment efficiency and treatment effect, so as to realize the lowering of the front teeth and effectively control the lip inclination of the front teeth.

The auxiliary arch of the utility model is formed by bending 0.7mm stainless steel wire, which provides more reliable pressing force without damaging the tooth root.

DETAILED DESCRIPTION

It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

Example 1

Referring to FIGS. 1 and 2 , a dental orthodontic appliance for simultaneously lowering and retracting anterior teeth comprises a main arch wire 1, which is sleeved in a bracket groove of a patient's dentition, and further comprises:

The auxiliary arch 2 is sleeved on the gingival margin of the patient's bracket and is ligated and fixed with the main arch wire 1. A plurality of force rings 4 are arranged on the auxiliary arch 2, and the force rings 4 are used to depress the lower front teeth.

In this embodiment, two force rings 4 are provided, and the two force rings 4 are respectively located below the mesial portion of the first bicuspids 5 on both sides.

During specific implementation, the force ring 4 is located at the front side of the bicuspids and at the lower back of the canines.

By setting the force ring 4 of the auxiliary arch 2 behind the canine 5, different magnitudes of depressing force can be applied by adjusting this point during specific use. The position of the force ring 4 can be adjusted upward appropriately during bending. At the same time, rubber chains are used on the bilateral force rings 4 to interact with the labial side of the lower front teeth to make it easier for the teeth to move backwards at the same time when being depressed.

In this embodiment, when the lower front teeth need to be retracted, a rubber chain is provided at the cutting edge of the front teeth bracket between the two force rings 4 , and the first end of the rubber chain is connected to one of the force rings 4 , and the second end of the rubber chain is connected to the other force ring 4 .

In this embodiment, the auxiliary bow 2 is formed by bending 0.7 mm stainless steel wire.

In this embodiment, auxiliary bow fixing parts 3 are provided at both ends of the auxiliary bow 2.

By arranging the auxiliary arch 2 on the lower side of the lower main arch wire 1, the relative depression of the mandibular teeth of the patient is achieved, that is, the posterior teeth are extended and the anterior teeth are depressed.

In this embodiment, an anchorage nail is also included. The anchorage nail is arranged at the posterior teeth position. The auxiliary arch 2, the main arch wire 1 and the anchorage nail are ligated and fixed by a fixing wire 7.

In specific implementation, for patients with high-angle deep overbite, anchorage pins are implanted horizontally in the bilateral posterior teeth area, and the auxiliary arch 2, the main arch wire and the anchorage pins are ligated and fixed, which can achieve absolute lowering of the lower anterior teeth and avoid the embarrassment of difficulty in implanting anchorage pins in the lower anterior teeth area.

In this embodiment, traction hooks are provided on the sides of the two auxiliary arch fixing parts that are away from each other, and the traction hooks are respectively ligated and fixed to the mesial buccal tubes of the second molars on both sides.

The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model are included in the protection scope of the utility model.
