Teeth misalignment, medically termed as malocclusion, is a common reason why many people get orthodontic treatment. Different classes of malocclusion can range from minor to severe condition. Sometimes, traditional braces are not enough to address this dental issue. According to this clinic providing orthodontics in Chatswood, NSW, malocclusion needs to be addressed as soon as possible to avoid other dental complications.


Understanding Malocclusion 

Malocclusion refers to the misalignment of teeth, which goes from minor crowding to extreme overbites or underbites. Generally, if one of your parents have this condition, you can acquire it as well.

Many individuals are not born with a normal bite and get orthodontic treatment for long-term arrangements.

The difference between your teeth and your jaw size can cause gaps, crowded teeth, and other forms of teeth misalignment. The reason is that mostly there is not sufficient space for permanent teeth to develop correctly.


Causes of Malocclusion

Regardless if it is a Class I, Class II, or Class III type of malocclusion, all classes of malocclusion can be because of the following causes:

  • Congenital disabilities, like a cleft lip and palate
  • Childhood habits, such as thumb sucking, tongue thrusting, too much pacifier use, and extended exposure to bottle-feeding
  • Teeth abnormalities, such as lost, impacted, or additional teeth
  • Unsuccessful procedures like improper placement of fillings, crowns, retainers, and braces
  • Jaw Damages and issues, such as jaw fractures, dislocations, tumors, cancers, temporomandibular joint dysfunction, and osteonecrosis


Symptoms of Malocclusion

The side effects of malocclusion are generally apparent, yet some are subtle and may incorporate:

  • Crowded, crooked, or irregularly aligned teeth
  • Jaw or teeth inconvenience while gnawing and chewing
  • Change in facial appearance
  • Mouth breathing
  • Biting your tongue, cheeks, or lips often
  • Developing a stutter or other speech issues


Three Classes of Malocclusion

There are three classes of malocclusion, namely:


Class I

This dentist in St Leonards notes that Class I is the most common form of teeth misalignment. This condition happens when the upper teeth slightly cover the lower teeth.


Class II

The dentist explains the three classes of malocclusion.Class II malocclusion is considered the most often issue addressing in the orthodontic practice. If a person suffers from Class II malocclusion, his upper teeth and jaw overlap the lower teeth and jaw. Class II malocclusion may also include craniofacial discrepancies, which can be changed when patients are adolescent.

Numerous treatment choices are available for the revision of Class II malocclusion, depending on what area of the craniofacial skeleton is influenced.

Generally, the treatments for Class II malocclusion include:

  • growth modification in terms of mandibular advancement
  • maxillary retraction
  • maxillary molar distalization


Class III

Class III type is a less frequently noticed clinical issue compared to Class II or Class I malocclusion. If a person has Class III malocclusion, his lower teeth and jaw overlap the upper teeth and jaw.

The widest reason for Class III malocclusions is excessive development of the mandible. These patients’ molar situation is referred to as mesio-occlusion, while the frontal relationship shows a negative overjet. An extreme Class III malocclusion might be related to distortion or lisping of sibilant, and alveolar speech sounds because of trouble elevating the tongue tip to the alveolar ridge.


Different Types of Malocclusions

You can see classes of malocclusion in the following various types of misalignment.



It is common to have a minor overlap of the lower front teeth. In any case, an expanded overbite can result in different issues, such as your anterior teeth biting down onto your gums or your bottom front teeth biting into the top of your mouth.

It would be best that an overbite gets treatment immediately. If untreated, there is more danger of creating a jaw disorder, tooth decay, or gum disease over time.

Possible treatment options for overbite can include:

  • Baby tooth extractions
  • Dental braces, retainers, and clear aligners
  • Cervical pull headgear, a standard dental device for children only
  • Jaw surgery, usually for adults with fully developed teeth and jaws



Underbite, also called anterior crossbite, occurs when lower front teeth overlap the upper front teeth.

Common underbite treatment choices include:

  • Baby tooth extractions
  • Dental braces, retainers, and clear aligners
  • Reverse-pull face mask for children only
  • Upper jaw expander for patients with developing jaws
  • Jaw surgery, usually for adults with fully developed teeth and jaws



A crossbite happens when your upper teeth nibble inside your lower teeth. This condition can occur on one of the two sides of your jaw and can also influence your front or posterior teeth.

Common treatment options incorporate

  • Dental braces, retainers, and clear aligners
  • Reverse-pull face mask for children only
  • Rapid palate expander for patients with developing jaws
  • Jaw surgery, for adults only



This condition is the most common orthodontic issues. Typically, overcrowding is because of an absence of room, causing teeth to overlap.

This type of malocclusion can be because of abnormal jaw development that runs in the family, uneven tooth development or loss, and a normal aging process.

Usual treatment choices for dental crowding incorporate:

  • Dental braces, clear aligners, and retainers
  • Dentofacial orthopedics
  • Dental veneers applicable for adults only


Open bite

An open bite occurs when the front teeth do not touch the lower teeth. Once the upper and lower front teeth do not contact, it brings about an opening that drives straight into the mouth. An open bite that influences the front teeth is called an anterior open bite. However, this issue can likewise happen on the sides of the mouth.The dentist will adjust the dental braces of the patient.

Open bite treatment options include:

  • High pull headgear applicable for kids only
  • Vertical jawline cup for children only
  • Roller devices for children as well
  • Bite blocks are suitable only for children
  • Jaw surgery for grownups with fully developed teeth and jaws



An overjet makes the upper teeth stretch out past the lower teeth horizontally. This protrusion can regularly meddle with biting food and talking correctly.

This condition can develop because of childhood habits, genetic factors, and irregular skeletal development. Neglected overjets can cause temporomandibular joint disorder (TMD).

Basic treatment choices for overjets include:

  • Dental braces, clear aligners, and retainers
  • Carriere device applicable for patients with developing jaws
  • Cervical pull headgear for youngsters only



Diastema, also known as gap teeth, is the condition where there is a space that presents between two nearby teeth. It is most common in the front two teeth.

Dentists can treat spaced teeth and diastema using:

  • Dental braces, clear aligners, and retainers
  • Dental bonding
  • Restorations for adults only
  • Dental Veneers for adults as well


Impacted tooth

An impacted tooth is a condition where the tooth is trapped in the gums. This condition happens because there is no space available for the tooth to emerge correctly. Treatment may incorporate surgical extraction or uncovering it so that the dentist can use dental braces.
