Description

Technical Field

[0001] The utility model relates to the technical field of oral cavity, in particular to an improved head cap extraoral arch corrector. Background Art

[0002] The working principle of the head cap-extraoral arch appliance combines the effects of functional appliances and mechanical appliances, and the application of extraoral force becomes the key to the entire correction process.

[0003] Traditional head cap muscle activator: The head cap extraoral bow appliance can be divided into two parts, the extraoral traction device and the muscle activator. The effect of the extraoral bow varies with the point of action, size, and direction. The backward traction force of the extraoral bow, plus the backward force of the muscle activator itself that extends the mandible forward and is transmitted to the maxilla, effectively controls the forward growth of the maxilla.

[0004] The disadvantages of the above prior art are as follows:

[0005] 1. There is no maxillary arch expansion device, and the narrow dental arch cannot be effectively solved;

[0006] 2. The front teeth area is covered with resin, and there is resin barrier between the teeth, which makes the front teeth movement and retraction effect poor;

[0007] 3. The extraoral bow is fixed in the resin holder and cannot be removed. It is not very convenient to wear it during the day and can only be worn when staying at home.

[0008] In summary, the utility model designs an improved head cap extraoral arch correction appliance. Summary of the invention

[0009] In view of the deficiencies in the prior art, the utility model aims to provide an improved head cap extraoral arch corrector with reasonable structural design, better correction effect and stronger practicality.

[0010] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an improved head cap extraoral arch appliance, including an appliance body, a lip arch, an extraoral arch tube, an extraoral arch and a mandibular lip stopper, the anterior tooth area of ​​the appliance body is provided with a lip arch, the premolar area of ​​the appliance body is provided with an extraoral arch tube, the extraoral arch tube is detachably provided with an extraoral bow, and a mandibular lip stopper is provided below the appliance body.

[0011] Preferably, a spiral expander is additionally provided at the maxillary portion of the appliance body.

[0012] Preferably, the extraoral bow tube is plug-fitted with the extraoral bow.

[0013] The utility model has the following beneficial effects:

[0014] 1. Add a spiral expander to the maxilla to solve the problem of narrow upper dental arch;

[0015] 2. Remove the covering resin from the front teeth area and design it into a labial arch. The lingual side of the front teeth can be properly buffered to facilitate the retraction of the front teeth and save the doctor's time for adjustment and grinding;

[0016] 3. An extraoral arch tube that can be inserted into the external oral arch is set in the premolar area, so that the extraoral arch can be removed and the child can wear it when going out during the day, thereby improving the therapeutic effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods;

[0018] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] Reference Figure 1 The present specific implementation adopts the following technical scheme: an improved head cap extraoral arch appliance, comprising an appliance body 1, a lip arch 2, an extraoral arch tube 3, an extraoral arch 4 and a mandibular lip stopper 5. The anterior tooth area of ​​the appliance body 1 is provided with a lip arch 2, the premolar area of ​​the appliance body 1 is provided with an extraoral arch tube 3, the extraoral arch tube 3 is detachably provided with the extraoral arch 4, and a mandibular lip stopper 5 is provided below the appliance body 1.

[0021] It is worth noting that a spiral expander is additionally provided on the upper jaw of the appliance body 1 .

[0022] In addition, the extraoral arch tube 3 is plug-fitted with the extraoral arch 4.

[0023] The improved head cap extraoral arch appliance of this specific embodiment is improved on the basis of the traditional appliance. The covering resin of the front tooth area is removed and designed into a lip arch. The lingual side of the front teeth can be properly buffered to facilitate the retraction of the front teeth and save the doctor's grinding time; a spiral expander is added to the upper jaw to solve the problem of narrow upper dental arch; the two sides of the appliance body 1 are connected with extraoral bows 4 through extraoral bow tubes 3. The extraoral bow 4 is detachable and can be worn by patients when going out during the day, which has better therapeutic effects.

[0024] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
