Malocclusion refers to any deviation from which dental condition?

1. Normal occlusion

2. Open bite

3. Crossbite

4. Class II occlusion

The correct answer is: Normal occlusion

Malocclusion refers specifically to any deviation from normal occlusion. Normal occlusion is the ideal alignment and contact of the upper and lower teeth when the mouth is closed. This ideal alignment allows for efficient chewing and proper function of the jaw, as well as a healthy bite relationship that promotes overall oral health. When there is a malocclusion, it indicates that the teeth do not fit together correctly, which can lead to issues such as tooth wear, jaw pain, and difficulty in chewing. Other specific conditions like open bite, crossbite, or Class II occlusion are distinct types of malocclusions, but the term malocclusion itself encompasses a broader range of misalignments from the normal occlusion scenario. Thus, normal occlusion serves as the baseline from which malocclusions are identified and categorized.
