The purpose of this guide is to clear our language around the occlusal plane and the mouth area. There is no streamlined standard set of definitions in looksmax.org and the orthodontic space in general.
Class 1 Malloclusison (Neutroclusion): Bite is distorted by the abnormalities in the individual teeth
Dental malocclusions are classified based on the positioning of the upper and lower molars. A class 1 malocclusion means that the molar position, or bite, is normal, but other teeth are misaligned in some way. These anomalies can include:
There are, in general, five types of Class 1 Malloclusians:
Class 1 before and afters:
May not look like much, but the teeth are instrumental in how the skin lays on your face, causing potential asymmetries.
Class 2 Malloclusions: Overjet and overbite
These are often used interchangeably, but they are not the same thing. Dental malocclusions are classified based on the positioning of the upper and lower molars.
Class 2 (or class II) malocclusions are characterized by upper molars that are too far forward than lower molars. This overbite can be caused by an overly prominent upper jaw or an underdeveloped lower jaw. Class 2 malocclusions can be subdivided into two categories, division 1 and division 2.
These malocclusions are some of the most difficult to treat because they either result from a lack of tooth eruption or lack of mewing when young. The overjet can be treated with Strouse springs that force the jaw forward to correct the bite (resulting in less recession). Type 2 can be explained by mew in this video:
Here are the treatments that can be used to treat class 2 malocclusions:
Class 3 is the rarest type of malocclusion.
Contrary to class 2, class 3 malocclusions are characterized by lower molars that are too far forward than the upper molars. People with this underbite often have a chin that appears too pronounced. Oral and maxillofacial health professionals sometimes use the term prognathism (protruding lower jaw) to refer to class 3 malocclusion.
Class 3 malocclusions can be further categorized based on their origin. They can be dental or skeletal in origin.
Several different treatments can be used to correct class 3 malocclusions. The right treatment is determined based on the malocclusion's origin and the problem's severity.

Class 1 Malloclusison (Neutroclusion): Bite is distorted by the abnormalities in the individual teeth
Dental malocclusions are classified based on the positioning of the upper and lower molars. A class 1 malocclusion means that the molar position, or bite, is normal, but other teeth are misaligned in some way. These anomalies can include:
- Overlapping or overcrowded teeth
- Rotated teeth
- Gaps between the teeth
- Asymmetry
- Open bite
There are, in general, five types of Class 1 Malloclusians:
- Class I Type 1: overlapping anterior teeth and upper or lower incisor and canine crowding
- Class I Type 2: vertical problem, protruding maxillary incisors with spaces between the teeth
- Class I Type 3: anterior cross-bite
- Class I Type 4: posterior cross-bite
- Class I Type 5: A lack of space for teeth posterior to the canines, premolars, or 2nd and 3rd molars.
Class 1 before and afters:

- Division 1: A class 2 division 1 malocclusion means that the molars are in the class 2 position, and the anterior teeth protrude. People with this type of malocclusion often experience a slackening of the lips. The lower lip rests behind the upper teeth, accentuating the discrepancy between the jaws.
- Division 2: With division 2, the molars are also in the class 2 position, but the soft tissues in the face and mouth react differently, exerting pressure that tilts the incisors towards the palate. This will create a weak-chinned look with excessive fat on the face. and later on, jowls

HOW TO TREAT CLASS 2 MALOCCLUSIONS
Since class 2 malocclusions occur in varying degrees of severity, several treatments can be used to correct the problem. Dental specialists (make sure you make your intentions very clear) can help you select the right treatment for your malocclusion.Here are the treatments that can be used to treat class 2 malocclusions:
- For children who are still growing: dentofacial orthopedic treatment to improve mandibular growth
- For mild cases: orthodontic treatment with fixed braces and intermaxillary elastics
- For adults with more severe malocclusion, orthognathic surgery is an option
Class 3 is the rarest type of malocclusion.
Contrary to class 2, class 3 malocclusions are characterized by lower molars that are too far forward than the upper molars. People with this underbite often have a chin that appears too pronounced. Oral and maxillofacial health professionals sometimes use the term prognathism (protruding lower jaw) to refer to class 3 malocclusion.
Class 3 malocclusions can be further categorized based on their origin. They can be dental or skeletal in origin.
- Dental class 3 malocclusion: the lower teeth are too far forward compared to the upper teeth
- Skeletal class 3 malocclusion: the entire jaw is improperly positioned due to a growth problem
HOW TO TREAT CLASS 3 MALOCCLUSIONS
Class 3 malocclusions will not correct themselves over time. It’s important to act promptly to prevent the problem from worsening, particularly if it appears young.Several different treatments can be used to correct class 3 malocclusions. The right treatment is determined based on the malocclusion's origin and the problem's severity.
Here are the treatment options:
- A palate expander to stimulate upper jaw growth in children
- Fixed braces for mild dental class 3 malocclusions in adolescents and adults (using springs most likely)
- Orthognathic Surgery is when the problem is skeletal in origin and is either severe or the person has finished growing
