Dental OSCE (Objective Structured Clinical Examination) Practice Exam

What distinguishes a hard reline from a soft reline for immediate dentures?

1. Hard relines are done immediately after placement

2. Soft relines can only be done once

3. Hard relines are done after 6 months

4. Soft relines require laboratory processing

The correct answer is: Hard relines are done after 6 months

A hard reline is typically performed when there is significant tissue healing and bone remodeling that has occurred, which often takes place several months post-initial denture placement. This reline involves using a more durable material that will provide a stable fit and improve comfort for the patient over a longer period. It is important to note that immediate dentures often experience changes in fit shortly after placement due to swelling and tissue changes, making a hard reline appropriate after the initial adjustments have settled, usually around six months after placement. In contrast, a soft reline uses a more flexible material that can alleviate discomfort and improve the fit of the denture for patients who experience sore spots or have sensitive tissues. While a soft reline may initially be placed soon after immediate denture placement, it can be performed multiple times as needed to accommodate ongoing changes in the mouth, which differs from the hard reline that is more permanent and conducted later. By understanding these distinctions, dental professionals can better manage patients' needs and ensure that dentures remain comfortable and functional as healing progresses.
