Dental OSCE (Objective Structured Clinical Examination) Practice Exam

Which factor should not be considered when setting denture teeth?

1. Tongue space

2. Occlusal relationship

3. Patient's age

4. Facial aesthetics

The correct answer is: Tongue space

Setting denture teeth involves careful consideration of several factors to ensure optimal function, comfort, and aesthetics for the patient. While tongue space is generally important for the overall design of a denture, it is not a critical factor when specifically determining the arrangement of the denture teeth themselves. The occlusal relationship is vital because it impacts how the upper and lower denture teeth meet during function, affecting the patient's ability to chew and speak effectively. Additionally, the patient’s age plays a role in tooth selection and arrangement, as it can influence the desired aesthetic outcome and the types of teeth that may be more suitable considering factors like wear and dental aesthetics. Facial aesthetics are equally important, as the positioning and appearance of the teeth must harmonize with the patient’s facial structure to achieve a natural and pleasing look. In contrast, while tongue space should be taken into account when designing the denture base to ensure comfort, it does not directly dictate the placement or selection of the teeth themselves. Thus, it is less critical compared to the other factors during the process of setting denture teeth.
