Description

Structural improvement of maxillary dilator

This invention is a "structural improvement of the maxillary expander", which involves a dental correction device, especially a technical field that can perform maxillary expansion surgery on the front teeth and posterior molars at the same time.

During oral orthodontic treatment, some patients have to undergo corrections for different conditions, such as irregular teeth, abnormal upper and lower jaws, or poor bite. In particular, some people have crooked teeth, and it is difficult to correct them to a neat arrangement because their dental arch is too small to provide sufficient space to accommodate all neat teeth. In this case, the doctor can use dental arch expansion correction to expand the upper jaw, and then adjust the shape and position of the upper and lower teeth so that the upper and lower teeth can be aligned and aligned.

It is known that when performing maxillary expansion correction, bone screws are not only placed in the gums at the front edge of the front teeth, but also in the front of the maxilla with elastic objects placed in between to achieve the purpose of gradual correction; in addition, an expander is placed at the back of the maxilla to expand the maxilla relative to the posterior molars and dental arch. Traditional orthodontic equipment is troublesome to set up and use, time-consuming and labor-intensive, and difficult to adjust, which is not ideal; especially the cumbersome orthodontic treatment process and the large amount of time spent, which often makes patients hesitate to move forward.

In view of this, the creator has developed this project, hoping to improve the shortcomings of existing maxillary expansion and correction equipment through the proposal of this project, so that maxillary expansion and correction can be more convenient and ideal, and meet actual needs.

In order to improve the above-mentioned shortcomings of the known maxillary expansion and correction equipment, such as being troublesome to set up and use, and being time-consuming and labor-intensive, the main purpose of the present invention is to provide a "structural improvement of the maxillary expander", which integrates the two known correction processes and equipment into one, and can use a single device to simultaneously perform maxillary expansion and correction on the front teeth and posterior molars; thereby, the setting of the equipment can be easier, more convenient and faster than the known structure, and the effect is better, so as to achieve the purpose of improving the expansion function.

The secondary purpose of this new device is to provide a "structural improvement of the maxillary expander" that integrates the two known correction procedures and equipment into one. It can use a single device to simultaneously perform maxillary expansion correction on the front teeth and the posterior molars; thereby shortening the cumbersome correction course, simplifying the correction period, and increasing the patient's willingness to undergo expansion correction.

To achieve the above purpose, the specific means of this case are: the maxillary expander, in a single structure, can cooperate with the rear traction element to pull the posterior molars, and at the same time use the front traction element to pull the front teeth, so as to achieve the effect of expansion and correction relative to the maxillary.

Preferably, the upper jaw expander includes two main bodies attached to the upper jaw of the oral cavity, and the distance between them can be adjusted by a screw.

Preferably, the main body is provided with a first perforation and a second perforation, and the first perforation and the second perforation are respectively used to fix the device to a suitable position of the upper jaw of the oral cavity through the maxillary bone nail.

Preferably, a third through hole is provided next to the second through hole of the body.

Preferably, the third through hole is provided with a hook bone nail, which is fixed to a suitable position on the upper jaw of the oral cavity; the top section of the hook bone nail can provide one or more hooking connections for the front traction element.

Preferably, one of the inner sides of the body is provided with a screw hole, which can provide a screw lock. The screw is divided into two parts, one of the screw teeth on both sides is a positive thread and the other is a reverse thread, and a screw block is provided at the intersection.

Preferably, one or more rear traction elements are connected to one of the outer sides of the main body.

Preferably, the front traction element and the rear traction element are strip-shaped.

Preferably, the front traction element is made of elastic material.

Preferably, the front traction element is a rubber band.

Preferably, the rear traction element is a metal wire.

Preferably, the rear traction element has a ring at its end.

The following is a detailed description of the content and effects of this invention "Structural Improvement of Upper Mandibular Expander" and a preferred embodiment of this invention with diagrams.

Please refer to the first and second figures of this case, "Structural Improvement of Upper Palate Expander", the upper palate expander 1 includes two main bodies 10 attached to the upper palate of the oral cavity, and the distance between them can be adjusted by a screw 15.

The main body 10 is provided with a first through hole 11 and a second through hole 12. The first through hole 11 and the second through hole 12 can be used to fix the device to a suitable position of the upper jaw 9 of the oral cavity through a maxillary bone nail 16. A third through hole 13 is provided next to the second through hole 12 of the main body 10. The third through hole 13 is provided with a hooking bone nail 19. The hooking bone nail 19 is fixed to a suitable position of the upper jaw 9 of the oral cavity. The top of the hooking bone nail 19 can provide one or more front traction elements 18 for hooking and connection. A screw hole 14 is provided on one inner side of the body 10. The screw hole 14 can provide a screw lock for the screw 15. The screw 15 is divided into two parts. One side of the screw teeth is a positive thread 151 and the other side is a reverse thread 152. A screw block 153 is provided at the intersection.

One or more rear traction elements 17 are connected to one outer side of the main body 10.

The front traction element 18 and the rear traction element 17 are strip-shaped objects; specifically, the front traction element 18 is an elastic material, such as a rubber band. The rear traction element 17 is a metal wire; the end of the rear traction element 17 is provided with a ring 171.

When the present case is implemented, as shown in the second figure, the upper jaw expander 1 can be fixed to the appropriate position of the upper jaw 9 of the oral cavity by using a plurality of upper jaw bone nails 16 to pass through each of the first perforations 11 and the second perforations 12; the spacing can be adjusted by using the positive thread 151 and the reverse thread 152 of the screw 15 therebetween; at the same time, the front row bone nails 94 are pre-set at the gums of the patient's front row teeth 93, and the front traction element 18 can be hooked to correct the dental arch there. Furthermore, by attaching the two rear traction elements 17 to the first posterior molar 91 and the second posterior molar 92, the dental arch can be expanded and corrected relative to the dental arch there.

From the above, it can be seen that the single maxillary expander 1 in this case can simultaneously satisfy the function of expanding and correcting the front and back dental arches, which is indeed more advanced than the known structure.

In summary, the technical content of this case, "Structural Improvement of Upper Mandibular Expander", fully meets the requirements for obtaining a new patent. This case can indeed be used in the industry, has never been seen in publications or publicly used before the application, and is not a technology known to the public.
