HOSA Dental Terminology Practice

Which term describes a deviation from Class I occlusion?

1. Separation

2. Malocclusion

3. Esthetic

4. Fetal molding

The correct answer is: Malocclusion

The term that describes a deviation from Class I occlusion is malocclusion. In dentistry, Class I occlusion is considered the ideal bite relationship wherein the upper and lower teeth align properly when the jaw is closed. Malocclusion refers to any misalignment of the teeth and the way the upper and lower jaws fit together, resulting in issues such as overcrowded teeth, gaps, overbites, underbites, and crossbites. This condition can affect not only the function of eating and speaking but also the overall health of the teeth and jaws. Understanding malocclusion is fundamental for dental professionals as it guides treatment planning for corrections such as braces, retainers, or other orthodontic interventions. Separation typically refers to the distance between teeth and does not inherently indicate a deviation from proper occlusion. Esthetic relates to the appearance or beauty, particularly of the smile or teeth, but doesn’t directly address occlusal relationships. Fetal molding is a term that refers to the shaping of a fetus within the womb and is not relevant in the context of dental occlusion.
