What It Means When Teeth Bite the Opposite Way

Hello.

This is Ceramic Dental Clinic, an orthodontic clinic in Gangnam.

As the year-end weather has turned much colder, I hope everyone has been staying healthy. 😊

Today, for those interested in adult orthodontic treatment, we will take a look at malocclusion and introduce an actual before-and-after case.

First, orthodontic treatment is a treatment performed to restore malocclusion to normal occlusion.

If there are no issues such as crowding, people may think their teeth are perfectly aligned just because the dental arch looks even on the outside. That belief can also lead to leaving problems that need orthodontic treatment untreated.

So, what kinds of malocclusion are there?

There may be names you have heard many times and some unfamiliar terms as well.

The malocclusion we will introduce today, along with this case, is "crossbite."

What is crossbite? Crossbite refers to an "inverted bite relationship" in which, when the mouth is closed, the lower front teeth cover the upper front teeth.

An example of crossbite

(This is the opposite of normal occlusion, where the upper teeth are positioned outside the lower teeth when the mouth is closed.)

Causes of crossbite A. When baby teeth are left untreated for a long time, causing the eruption direction of the permanent teeth to change

B. When the lateral growth of the upper jaw is insufficient compared to the lower jaw

C. When there is a habit of thumb sucking, or pushing the tongue or jaw forward

The Ceramic Dental Clinic crossbite before-and-after orthodontic case we will look at today is a case treated for crossbite, protruding lower jaw, and non-extraction orthodontics.

Treatment plan

🔎 Age at start of treatment: 24 🔎 Reason for starting treatment: crossbite, spaced teeth 🔎 Treatment duration: about 1 year and 2 months

1. Problem diagnosis

• Crossbite of the front teeth

• Protruding lower jaw

• Spaced teeth

The tooth alignment was also poor, and asymmetry was present as well.

2. Treatment method

• "Non-extraction orthodontics" to improve malocclusion (estimated duration: 24 months)

• Use of Clippy C braces and mini-screws

Treatment results Actual treatment time: 14 months

You can see that the crossbite, irregular tooth alignment, and protruding lower jaw have been clearly improved.

Although the estimated orthodontic period was 24 months, due to rapid tooth movement, treatment was completed quickly in 14 months, 10 months earlier than expected.

You can confirm that the lower lip moved back, and the front teeth that had been in a crossbite have settled into normal occlusion :)

Crossbite is not only an aesthetic issue, as it makes the lower jaw appear more prominent and can be noticeable when smiling, but is also related to chewing function, so it is very important to improve it through orthodontic treatment.

In particular, during the growth period, it can help prevent prognathism. (Already developed lower jawbone is an exception)

Ceramic Dental Clinic treats not only adolescents but also adults in their 40s and 50s for orthodontic treatment, and has handled a variety of cases such as deep bite, open bite, crossbite, as well as crowded teeth, underbite, asymmetry, and gaps between teeth.
