What is Malocclusion?

Malocclusion is a dental condition where the upper and lower teeth don't align correctly when the jaws are closed. It can result in issues like overbites, underbites, or crowded teeth.

Malocclusion is a medical term that refers to the misalignment of teeth. When teeth are out of alignment, it becomes more challenging to chew, bite, and talk. 

But an orthodontist, who is highly trained in treating all types of malocclusions, may successfully reposition your teeth in the jaw. 

Orthodontic therapy employs a variety of tools and techniques to straighten a misaligned jaw and crooked teeth.

Classification of Malocclusion

Malocclusion, or misalignment of the teeth when the jaws are closed, is typically classified into different categories based on the specific nature of the misalignment. 

The classification system most commonly used by orthodontists is the Angle Classification System, which categorizes malocclusion into three classes:

Class 1 Malocclusion

An overlap of the upper teeth over the lower teeth is known as a class 1 malocclusion, often referred to as a class 1 occlusion and a class 1 bite. It occurs as a result of childhood thumb-sucking or chronic bottle use. 

However, it doesn't significantly damage your bite and can be corrected with minimal malocclusion treatment. 

Three types of class 1 malocclusion exist in teeth

  • In type 1, the teeth slant towards the tongue. 
  • Type 2 has upper teeth that protrude out in narrow arches, and bottom teeth are inclined towards the tongue. 
  • The upper teeth are crowded and incline towards the tongue in type 3 malocclusion.

Class 2 Malocclusion

The top teeth protruding over the lower teeth is another sign of class 2 malocclusion, sometimes referred to as class 2 occlusion and class 2 bite. 

However, this severe malocclusion will dramatically alter your bite. Early orthodontic treatment is required. 

Your teeth's alignment may need to be corrected over several visits as a part of malocclusion treatment. 

However, it is treatable permanently. There are 2 subtypes of class 2 malocclusion. 

  • In division 1, upper teeth slant towards the lips. 
  • In division 2, The upper central incisors incline towards the tongue.

Class 3 Malocclusion

Class 3 malocclusion is a kind of underbite in which the lower teeth protrude over the upper teeth. 

It is also referred to as class 3 occlusion and class 3 bite. When some upper teeth and some lower teeth overlap, it can also be a crossbite. 

Based on how the teeth are positioned, class 3 malocclusion is further split into 3 categories. 

  • Teeth of type 1 produce an unusually formed arch. 
  • The lower front teeth are inclined towards the tongue in type 2 malocclusion. 
  • Additionally, type 3 has an irregular upper arch and top teeth are inclined towards the tongue.

What Are The Different Types Of Teeth Malocclusion?

The following list includes the numerous sorts of bites that teeth can exhibit:

1. Overcrowding

Overcrowding is a frequent problem that is frequently caused by a shortage of space because of overlapping or misplaced teeth.

Crowding occurs when there is either too much or not enough room for the teeth, and this can have a negative effect on the emergence of permanent teeth.

2. Openbite

An aperture that leads directly into the mouth is created when the upper and lower front teeth do not overlap with another one. The issue of an open bite can also develop on the mouth's sides.

3. Overjet

An overjet occurs when the top front teeth cross over the lower front teeth horizontally and obstruct speech and eating.

4. Overbite

Although some overlapping of the lower front teeth is normal, an enhanced overbite can occur when the lower front teeth can additionally bite into the roof of the mouth when the upper front teeth are biting directly into the gums.

5. Underbite

An underbite, sometimes referred to as an anterior crossbite, is caused when the lower front teeth are placed further forward than the higher front teeth.

6. Crossbite

When the upper front teeth bite directly inside the lower teeth, a crossbite can occur on one or both sides of the jaw. Your front or back teeth may also be affected by the illness.

7. Diastema

The space between two neighbouring teeth, typically the front teeth, is referred to as a diastema.

8. Unaffected Tooth

An impacted tooth is one that needs to be removed or exposed in order to fit a brace because it cannot normally erupt from the gum.

9. Missing  tooth

This disorder, also known as hypodontia, develops as a result of trauma or poor tooth development.

How to Diagnose Malocclusion?

During routine dental examinations, a dentist looks for malocclusion in youngsters, and if the child's teeth seem out of alignment or his jaw is distorted, an orthodontist may be consulted. Next, the orthodontist will look at:

  1. Medical background of the child to determine any previous health issues in the mouth and teeth.
  2. X-rays of the face and teeth.

According to the American Association of Orthodontists, every kid should have a dental examination with an orthodontist by the age of seven, and routine dental checkups should start at twelve months. 

Regular dental checkups aid in the early detection of dental issues so that timely treatment can be started.

How to Treat Malocclusion of Teeth?

1. Braces

One of the most effective and time-tested malocclusion therapies is braces. Before beginning treatment with braces for children and teenagers, it may be necessary to pull some teeth. 

The teeth and jaw are straightened by braces, improving your smile and incorrect bite. Your orthodontist may recommend lingual braces, ceramic, or metal braces. 

To a large extent, the result will depend on the severity of the alignment of the teeth.

2. Retainers

For teeth malocclusion, removable orthodontic appliances are preferred due to their convenience. Detachable devices include, among others, headgear and retainers. 

Retainer trays help to maintain the alignment of teeth that have been straightened by orthodontic treatments like braces. 

The alignment of teeth is straightened with the help of orthodontic procedures like braces maintained by retainer trays. 

Depending on the degree of the misalignment and the patient's cooperation with wearing their specially constructed removable retainers or headgear, the course of treatment for a misaligned bite might vary.

3. Clear Aligners

All types of dental malocclusion, including underbites, open bites, overbites, and crossbites, can be corrected with clear aligners. 

It is a set of aligner trays made of clear plastic. It is invisible to others. You must wear clear aligners for between 20 and 22 hours every day, and they are removable. 

It applies pressure to the jaw and teeth throughout that period to align them properly. You can transform your smile with clear aligners while remaining unobtrusive.

Conclusion

Orthodontic therapy typically lasts up to two years, but it may take longer for adults. 

If you're an adult and your orthodontist proposes having your jaw operated on, you might want to consider getting a second opinion to make sure you make the best choice possible. 

The majority of malocclusions are inherited and cannot be treated. You discourage your kids from sucking their thumbs to prevent malocclusion. 

When teeth are lost, malocclusion can occur. If you lose a tooth, you might need dental implants or a bridge to fill the teeth gap.

Malocclusion treatment takes time. While your teeth are carefully corrected, braces will likely be on your teeth for several months to more than a year. 

You might need to modify some of your daily routines to make room for your braces and ensure they don't negatively impact your general dental health. 

As you wear braces, discuss oral hygiene with your healthcare practitioner.

How to Fix Malocclusion without Braces?

Adults with minor to moderate malocclusion of the teeth can correct their bites and smiles by wearing a clear plastic aligner. 

These appliances are removable, so the patient wears them as directed by the dentist until the aligner forces the teeth into the proper position.

Can Invisible Aligners Fix Class 3 Malocclusion?
