Signs and Symptoms of Malocclusion

What is Malocclusion?

Malocclusion is also known as poor bite. Malocclusion is basically misalignment of the teeth. The term bite means how upper and lower jaws are arranged. Besides this the further terms which can be used are: crowded bite, cross bite, underbite, open bite and overbite.
Malocclusion is mostly a genetic disease but sometimes, it is a cosmetic problem. Moreover, crooked teeth are difficult to care for properly, thus tooth decay or loss may start earlier. It may lead towards difficulty in speaking and eating if the problem is severe.

Types of Malocclusion

Malocclusion Classification

On the basis of the arrangement of teeth, malocclusion is classified into three basic types. These include:

  • Class 1 Malocclusion

Class 1 malocclusion is the most common type and less severe as well. There is slight overlap of upper molars with lower molars in good position, but other teeth are either spaced or crowded. 

  • Class 2 Malocclusion

It is also known as retrognathism (or retrognathia). Class 2 malocclusion is characterized as overbite in which the upper jaw and teeth severely overlap the lower jaw and teeth. The lower jaw has a much smaller size than usual.

  • Class 3 Malocclusion

The third type of malocclusion is diagnosed as the larger size of lower jaw than upper jaw thus also known as prognathism, which means protrude lower jaw and teeth. Commonly it is named as underbite, as the lower jaw overlaps with the upper jaw.
