HOSA Dental Terminology Practice

What occurs during centric articulation movement?

1. The mandible moves side to side

2. The condyle rests in the temporal bone

3. The jaw opens wide for examination

4. The molars occlude with upper teeth

The correct answer is: The condyle rests in the temporal bone

During centric articulation movement, the condyle rests in the temporal bone. This position refers to the relationship between the mandible (lower jaw) and the maxilla (upper jaw) when the mouth is closed in a neutral position where the cusps of the teeth interdigitate most effectively. In this state, the condyles are located in the glenoid fossae of the temporal bone, providing a stable and optimal relationship that is essential for functions such as chewing and speaking. This resting position is critical for dentists and dental professionals to understand because it serves as the reference point for dental treatments, including the design of restorations and orthodontic interventions. Recognizing this position helps assess any deviations in occlusion or joint function.
