Dental OSCE (Objective Structured Clinical Examination) Practice Exam

When is a denture reline indicated?

1. When there is a broken tooth

2. When there is a broken denture base

3. When the ridges have resorbed

4. When the denture is stained

The correct answer is: When the ridges have resorbed

A denture reline is indicated when the ridges have resorbed. Over time, the alveolar ridges undergo significant changes due to bone resorption, which can lead to ill-fitting dentures. The fit of the denture can become loose as the underlying bone structures change, resulting in discomfort and difficulties with function, such as chewing and speaking. Relining the denture involves adding a new layer of material to the inner surface of the denture to create a more precise fit against the reshaped gums. This process can improve retention and stability, enabling the patient to maintain better function and comfort with the denture. The other scenarios, such as a broken tooth or a broken denture base, typically require repairs, not relining. Similarly, staining of the denture, while it may affect aesthetics, does not alter the fit and would not necessitate a reline. Instead, stained dentures might require professional cleaning or replacement if the staining is severe. Thus, the need for a reline specifically correlates with the resorption of the ridges.
