It may be a new word to you. “Malocclusion” is a technical term for crooked, crowded, malaligned or protruding teeth which do not fit together properly. Literally, the word means “bad bite.”
The term “occlusion” refers to the relationship of the teeth with one another when the jaws are closed. For a “bite” to be functional and esthetic, not only must there be a precise arrangement between the teeth but there must be a harmonious relationship between the jaws as well.

Any deviation from this “ideal” relationship is considered a “malocclusion”. It refers to any inadequate relationship between the teeth and/or jaws.

The most common malocclusions have crooked, crowded, rotated teeth, excessive overbite, teeth that are “sticking out”, teeth that do not touch one another when biting, “scissor bites”, etc.
