Relining of denture:
- A- remove all or part of fitting surface of the denture and add acrylic.
- B- add acrylic to the base of the denture to increase vertical dimension.
both options can be part of denture relining, depending on the specific reason for the procedure:
A. Removing part of the fitting surface and adding acrylic:
This is used to adjust the fit of a loose denture due to changes in the gums or bone. Removing material creates space for new acrylic, resulting in a tighter fit. This is often called a soft reline for improved comfort and tissue adaptation.
B. Adding acrylic to the base of the denture to increase vertical dimension:
This is used to increase the bite height when the denture has worn down or the jaw has changed. Adding acrylic builds up the material between the denture and gums, bringing teeth closer and restoring vertical dimension. This is often called a hard reline for stability and wear resistance.
Correct Answer:
Therefore, the correct answer depends on the reason for relining:
- Loose denture:
Choose option A (remove and add acrylic) for a soft reline to improve fit.
- Decreased bite height:
Choose option B (add acrylic to base) for a hard reline to increase vertical dimension.
In some cases, both options might be used together if both improved fit and increased vertical dimension are needed.
It's important to consult a dental professional to determine the specific reason for your denture relining and recommend the appropriate approach.
