HOSA Dental Terminology Practice

What does mesioclusion refer to in dental terminology?

1. Class I malocclusion

2. Class II malocclusion

3. Class III malocclusion

4. Neutral occlusion

The correct answer is: Class II malocclusion

Mesioclusion refers to Class II malocclusion, where the first molar of the lower jaw is positioned further back than the first molar of the upper jaw. This situation often results in an overbite, where the upper teeth significantly overlap the lower teeth. In this classification, the relationship of the dental arches is such that when the jaws are closed, the upper teeth position is ahead, contributing to aesthetic and functional challenges. Understanding this classification is essential for dental professionals as it guides treatment planning for correction, which may involve orthodontics or other forms of dental intervention. Recognizing that a Class II malocclusion denotes a specific type of bite relationship distinguishes it from other categories like Class I, which is normal occlusion, or Class III, which involves the lower jaw being positioned forward relative to the upper jaw.
