What is the bone earth, and what is the bone earth

The earth covers the sky"In medicine, it is called "anterior crossbite", also known as "pocket teeth". Ground wrapping is the most common developmental disorder of the jaw. Normally, the teeth in the upper jaw cover the teeth in the lower jaw.

In turn, the lower teeth stretch forward, and the lower teeth cover the upper teeth, which is very unsightly.

The bony ground is more severe, and the bone growth defect is manifested as hypergrowth of the lower jaw and dysplasia of the upper jaw. Braces are required for surgery to correct it. Generally, braces are more than one year + two months of operation + more than half a year of post-correction.

So it takes two or three years. The cost is about three times that of the tooth.

If you want to judge whether it is bony or not, it is bony if you look like you have a long face and a chin that is clearly protruding.

There are three types of bony ones, one is that the jaw develops too fast and is too long. The second is that the upper jaw is too short. The third is both.

Under normal circumstances, when the upper and lower teeth occlude, the upper front teeth should bite on the outside of the lower front teeth, if the opposite is true, the lower front teeth bite on the outside of the upper front teeth, which is medically called "anterior teeth anti-bite", "cross-bite", commonly known as "ground baotian", also called "pocket teeth".

It is necessary to take a film to check the specific situation, if there is a bony malocclusion, that is, the mandible is more protruding, and the simple orthodontic ** can not be satisfied, and the orthognathic surgery of maxillofacial surgery is required, and then orthodontics**. If it is a simple malocclusion of teeth, orthodontics can be performed**.

It's you, you've missed the best time, you're getting older. Regretful!! This means that simple orthodontics is no longer enough to solve your profile problems. It is recommended that you do it earlier**. The more you drag it out, the worse it gets.

The lower front teeth cover the upper front teeth, just like the ground wraps the sky, so it is called the earth wrapping the sky. There are two common types: bony envelope and dental envelope, so the corresponding ** methods are also different. So, how to distinguish between bone and tooth?

How to distinguish between bone and tooth?

According to experts, dental enveloping is simply caused by the misalignment of teeth, and does not involve abnormal jaw development. The main reason is that the upper and lower jaws are abnormally developed, and from the appearance of the lower jaw is more prominent, the most direct way is to go to a regular hospital for an examination to see if the jaw development is normal.

Generally speaking, as long as the dental ground is orthodonticed, it can be **, if it is a bony ground package, in addition to orthodontics, it must be combined with surgical means**. Therefore, we have been advocating that if there is a phenomenon of ground enveloping, it should be timely, the best period of ground enveloping is the deciduous period, between 3-5 years old, if the best correction period is missed, it will affect the future development of maxillofacial type.

There are two types of earth-covered sky: one is dental earth-like and the other is bony earth-covered sky.

Bony undergrowth is more severe, skeletal growth defects, bony undergrowth is manifested as underjaw hypergrowth, upper jaw dysplasia. Braces are required for surgery to correct it.

Dental coverage refers to the fact that the teeth do not grow well, the lower teeth protrude outward, the upper teeth protrude inward, and the bones are normal. It can be corrected simply by wearing braces, which is not serious. Generally, it can be corrected in more than a year.

Osteogenesis is more severe, with defects in bone growth, manifested as overgrowth of the lower jaw and dysplasia of the upper jaw.

Judging whether the earth is bony or not, from the appearance, the chin is obviously protruding, and the face looks very long is bony.

That.

1. Dental envelope is simply caused by tooth misalignment, and does not involve abnormal jaw development.

That. Second, the main reason is that the upper and lower jaw is not properly developed caused by the dichondria, from the appearance of the lower jaw is more prominent, the face is longer is the bony envelope. However, visual observation is not completely accurate, and the most direct way is to go to a regular hospital for an X-ray examination to see if the jaw development is normal.

For more information.

Dental-incompatible.

It is mostly caused by local obstacles in the process of tooth eruption or replacement, and often manifests as simple anterior tooth reversal. The reverse coverage is smaller, and the molars are neutral or close to neutral relationships. The shape and size of the lower jaw were basically normal, there was no obvious abnormality in the upper and lower jaws, the chin was not protruding, and the face and face were basically normal.

Bony envelope.

It is mostly due to factors such as genetics and diseases, except for the anterior teeth, which often show large reverse coverage. Molars are mesial malformed with jaw deformity. May present with blunt mandibular angle, long mandibular body, short mandibular ramus, or underdeveloped anterior maxillary portion.

The chin is prominently protruding, and the lower jaw often does not recede on its own. The face is often concave and sometimes accompanied by an open jaw deformity. It is difficult to correct and usually needs to be solved by surgical orthodontics.

Hello, I'm glad to answer for you, if it is caused by the cause of the bone, it is necessary to pass ** to be diagnosed, and there is almost no way to distinguish it. It is recommended to go to the dental department of a regular hospital to take an X-ray examination and diagnosis, and correct the teeth in a targeted manner, and the ground can be started at the age of 4, I hope my answer will be helpful to you, I wish you good health.

1.The bones are "covered with the sky" refers to bony deformities with a prominent mandible. On the other hand, the tooth is "enveloped" by dental deformity in which the mandibular teeth are more sloping outward (labial). And, of course, there are hybrids.

2.Whether it is bony or dental depends on your oral condition. According to what you said, your condition should not be particularly serious, and you generally do not need surgery, as long as you wear appliances, it will take more than two years.

The age can be corrected, the cost depends on the place to see the hospital, generally at least 4000-5000, a good hospital is a little more than 10000. Wearing aligners is a bit troublesome, so you need to maintain good oral hygiene and not bite hard objects. For bony surgery, the cost of surgical correction is estimated to be higher.
