Introduction

The effect of laughing and smiling on a person’s face is clear to everyone. As the poets have said since ancient times, “I saw your smile and the foundation of my heart fell apart” in order to have a beautiful smile, the appearance of our mouth and teeth must be good so that we can laugh out loud without anxiety. One of the problems that make you anxious about smiling is the crossbite problem, which is discussed in this article from the website of Dr. Ahmad Shibani Nia.

What is dental crossbite?

First, you need to know the standard position of the teeth, where the upper jaw teeth are 2 mm ahead of the lower jaw teeth. In crossbite, the teeth of the upper jaw are placed inside the teeth of the lower jaw. In fact, a crossbite is a type of malocclusion in which the teeth of the upper jaw and the teeth of the lower jaw do not fit together. In other words, this problem is serious and its treatment is also necessary, because if this problem is not treated, with the growth of the lower jaw, it will bring severe and serious abnormalities to the jaw and mouth.

In a child when the teeth are growing, if an external force can change the direction of the growth of the jaw bones, it will cause this complication. Among the reasons for its creation, we can mention heredity, which is the most important factor, and the following reasons:

1. Heredity factor
2. Finger sucking in childhood.
3. mouth breathing
4. Complications of abnormal surgeries such as cleft lip and cleft palate that prevent the growth of the jawbone.
5. Remaining baby teeth in the mouth for a long time.
6. Crowding of teeth, which causes the teeth to be misaligned and the lower jaw to be pushed forward by creating pressure.
7. Delayed or abnormal tooth eruption.

Types of crossbites

This jaw abnormality is in the category of skeletal class III (Skeletal Cl lll) and often occurs in childhood. In addition to having a bad effect on a person’s appearance and making a person’s jaw look ugly, it also has a bad effect on a person’s health. Now, it doesn’t matter if all the teeth don’t match or even one tooth, all of them are called crossbite. This abnormality has three different types:

• Posterior crossbite

This anomaly is related to the posterior teeth. The placement of the back teeth of the upper jaw, behind the back teeth of the lower jaw, is called a posterior crossbite.

• Anterior crossbite

This abnormality is related to the front parts of the mouth. The placement of the front teeth of the upper jaw behind the front teeth of the lower jaw is called an anterior crossbite. This complication is similar to underbite, but it is not exactly the same and can be identified using the differences.

• One-way and two-way crossbite – or cheek crossbite

A crossbite that affects both sides of the mouth is called a bilateral crossbite, and a crossbite that affects only one side of the mouth is called a unilateral type. The treatment method for both is almost the same, but the mechanism and structure that the orthodontist will choose to treat each one is certainly a little different. This type of crossbite is also called cheek because the teeth on one side will be closer to the cheek.

Abrasion of the teeth and difficulty in speaking and mispronunciation are other problems that require the treatment of this disease. It should be noted that if the treatment is not done correctly, it will lead to unevenness and asymmetry of the jaw and cause joint disorders in the lower jaw. Depending on whether the crossbite is severe or mild, its type and the age of the person, there will be different treatments.
2. If this complication is not severe, this problem can be solved with dental orthodontics, especially fixed orthodontics for people over 12 years old. This way is mostly used for children whose jaw growth is not yet complete. This type of treatment is long-term, which means that orthodontics must be performed for at least two years for complete treatment.

1. Using palate expanders or palatal expanders is also a therapeutic way to widen the palate. This device is a type of orthodontics that attaches to the roof of the mouth. Sometimes specialists pull milk teeth for the healthy growth of permanent teeth in children and use small mobile orthodontic devices inside the mouth to treat them. Sometimes mild crossbites can be treated by veneers, bonding and reshaping the teeth.
2. Jaw surgery is also used to widen the palate and align the two jaws. Now, if a person comes after the age of 18, the treatment is orthosurgery due to the stoppage of growth of the two jaws. Orthosurgery is actually the combination of orthodontics and jaw surgery, and this method is used in severe cases of crossbite.
