K07: Dentofacial anomalies [including malocclusion]

K07.2: Anomalies of dental arch relationship

The top row of teeth consists of all the teeth in the upper jaw. The bottom row of teeth consists of all the teeth in the lower jaw. The two rows of teeth usually rest on each other in a particular way when you bite.

When the rows do not align correctly, there are different ways in which your appearance can vary. For example, the row of teeth in the lower jaw might sit further forwards or backwards than usual. The row of teeth in the upper jaw can also sit too far forwards. They then jut further over the lower teeth than usual. It may also be that the two rows of teeth do not even touch one another at the front or sides when your mouth is closed. If the rows of teeth are displaced to the side, the side teeth will not align properly with one another. It may also be that the center of the top row of teeth and the center of the bottom row of teeth do not align exactly. Normally when you bite, the centers of the two rows of teeth meet one another.
