HOSA Dental Terminology Practice

What is described by the term 'distoclusion'?

1. An incorrect occlusion relationship of Class II

2. See: Class III Occlusal Relationship

3. A normal bite relationship

4. A dental term for tooth grinding

The correct answer is: See: Class III Occlusal Relationship

Distoclusion refers to an incorrect occlusion relationship where the buccal and lingual cusps of the teeth do not meet appropriately, typically described in the context of Class II malocclusion. In Class II malocclusion, the first molar of the lower jaw is positioned further back than normal in relation to the upper jaw. This causes a relationship where the upper teeth may protrude or the lower teeth may recede, effectively leading to distoclusion. The other options focus on different concepts: some refer to Class III relationships, which describe a different occlusal scenario where the lower molars are positioned further forward than the upper ones; others mention a normal bite, which would not apply to distoclusion, and tooth grinding, which is known as bruxism and also does not relate to the occlusion classification. Understanding these distinctions helps in recognizing the importance of proper occlusal relationships in dental health.
