Description

Ware draw gear is rescued in stealthy correction of no support groove with vacuole

Technical Field

The utility model relates to the technical field of orthodontics, concretely relates to ware draw gear is rescued in stealthy nothing support groove with vacuole.

Background

The bracket-free invisible appliance is an appliance which is designed by a computer in an auxiliary way, is formed by high polymer material film pressing through 3D printing and can be taken off and worn. Compared with the traditional fixed appliance, the utility model has the following advantages: more beautiful: invisible and transparent; more comfortable: the eating is not affected, and the mucous membrane of the oral cavity is not stimulated; the oral hygiene maintenance is convenient: can be taken off and worn at any time without affecting tooth brushing; is convenient and fast: the frequency of the return visit is low, the interval is long, and the return visit operation is simple; mild strength and low pain.

As shown in fig. 1 and 2, the bracket-free invisible correction technology is inevitably used for traction between the jaws during treatment. The traditional traction device without the bracket invisible appliance has two types, one type is that a doctor or a technician directly uses a special instrument to make a 'traction hook' at the gum position 1 on an appliance body for carrying out the intermaxillary traction. Thus, the operation time beside the chair of the doctor is increased, the integrity of the edge of the appliance is damaged, the appliance cannot wrap the teeth well, and the possibility of breakage of the appliance is increased. In addition, the traction force of rubber band acts on and rescues the ware, can make and rescure the condition that ware and tooth appear not laminating to reduce tooth and remove efficiency, influence and rescure the effect. Another way is to make a window at the gingival margin of the appliance and bond metal or resin buttons for traction. This method ensures that traction forces act on the teeth, but also destroys the integrity of the appliance rim, affecting the effectiveness of tooth movement. In this way the position of the traction force is also limited, while comfort and aesthetics are affected.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a no support groove stealthy ware draw gear of rescuring with vacuole, to have the drawing vacuole of fluting and combine together with the maintenance vacuole, form special device, under the effect of traction, remove the tooth. The device not only can ensure that the appliance is more attached to the teeth, but also can ensure that the traction force really acts on the teeth and dentition. The traction method for avoiding opening a notch at the gum or bonding the traction buckle by opening the window not only can ensure that the appliance is more attached to the teeth, but also can be matched with the retention accessory, so that the traction force can better act on the target tooth position, the processing and the production and the chair-side operation of a doctor are more convenient, and the traction method has important significance.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is:

a bracket-free invisible appliance traction device with vacuoles comprises an upper tooth socket and a lower tooth socket, wherein the upper tooth socket and the lower tooth socket are respectively connected with the vacuoles. The inner side of the vacuole is supported by accessories. The vacuole has a groove facing the gum and a traction line is connected between the two grooves.

Cavitation bubbles can be classified as retention vacuoles and traction vacuoles. The retention vacuole has an attachment support on the inside. The traction vacuole has a groove, the upper jaw vacuole faces upwards, the lower jaw vacuole faces downwards, and a traction line is connected between the two grooves.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses regard vacuole or the vacuole that has the fluting as a whole with the ware of rescuring, slot the vacuole in process of production, form special device, pull through the rubber band and remove the tooth. The device can be arranged for the upper and lower jaws respectively according to the correction requirement. Avoid doctor from beating "draw hook" or windowing and gluing and draw the knot in the ware of correcting near gum department by hand, reduced doctor's chair side operating time, improved the expression rate of correcting the power, still promoted comfort and the pleasing to the eye degree of patient in the wearing process. The utility model is only suitable for the invisible correction technology without the bracket.

Detailed Description

The present invention is described in detail below by way of examples, which should not be construed as limiting the scope of the invention.

Example 1: as shown in fig. 3, 4 and 5, a bracket-free invisible appliance traction device with a traction cavity and a retention cavity performs traction on mandibular teeth.

A bracket-free invisible appliance traction device with vacuoles comprises an upper tooth socket 5 and a lower tooth socket 6. The upper tooth socket 5 and the lower tooth socket 6 are respectively connected with two vacuoles 3, wherein, the inner side of one vacuole 3 is provided with an accessory support adhered on the teeth, and the other vacuole 3 is provided with a groove 4. The traction wire 2 is connected between the two vacuoles 3 with grooves 4.

Manufacturing the upper tooth socket 5 and the lower tooth socket 6: adhering accessories at the part simulating the tooth model of the patient, wherein the shape of the accessories is similar to that of the vacuole, and the part is selected as follows: vacuoles are formed at the corresponding sites, taking into account the requirements of the treatment.

Printing a resin model according to a tooth model drawing of a patient and the position design of accessories, then directly pressing a film on the resin model by using a high molecular polymer through a hot pressing process to manufacture an upper tooth socket 5 and a lower tooth socket 6, and forming vacuoles 3 at corresponding positions of the upper tooth socket 5 and the lower tooth socket 6.

In use, one end of the traction wire 2 is sleeved in the groove 4 of the upper dental mouthpiece 5, the other end of the traction wire 2 is sleeved in the groove 4 of the lower dental mouthpiece 6, and the lower-jaw canine teeth are molar moved with the teeth of the upper jaw as a support.

Example 2: referring to fig. 3, 4 and 5, a bracket-free invisible appliance traction device with cavities, taking orthodontic III traction to assist the far-middle movement of mandibular teeth as an example, one cavity 3 is arranged at the first molar of an upper shell 5 and the other cavity 3 is arranged at the cuspid of a lower shell 6. A groove 4 is arranged on one side of the two vacuoles 3 close to the gum.

When in use, one end of the rubber band 2 is sleeved at the groove 4 of the upper dental mouthpiece 5 of the upper jaw, the other end is sleeved at the groove 4 of the lower dental mouthpiece 6 of the lower jaw, and the teeth of the upper jaw are used as anchorage to move the lower canine teeth to the molar teeth to the far middle.

Example 3: as shown in fig. 3, 4 and 5, a bracket-free invisible appliance traction device with a cavity comprises an appliance body, wherein the appliance body comprises an upper tooth socket 5 (an upper appliance) and a lower tooth socket 6 (a lower appliance), the upper appliance and the lower appliance are respectively connected with the cavity, the cavity is provided with a slot, and the cavity and the appliance are connected into a whole. The vacuole and the vacuole with the groove are mutually supported and used in a combined way.

Adhering the accessory to the part of the patient's tooth, wherein the shape of the accessory is similar to that of the vacuole, and the part is selected from the following components: the appendages and vacuoles are the fulcrum of the correction, taking into account the requirements of the treatment. The grooved vacuole is used for traction, and the vacuole is attached to the corresponding accessory on the tooth, so that the traction force is really applied to the tooth.

Example 4: as shown in fig. 3, 4 and 5, the bracket-free invisible appliance traction device with the vacuoles comprises a bracket-free invisible appliance body, wherein the bracket-free invisible appliance is provided with traction vacuoles (comprising a groove 4) and retention vacuoles (provided with accessory supports).
