What process is known as relining in dentistry?

1. Creating a new dental impression

2. Resurfacing the tissue side of a prosthesis

3. Removing decay from a tooth

4. Shaping teeth for braces

The correct answer is: Resurfacing the tissue side of a prosthesis

Relining in dentistry refers specifically to the process of resurfacing the tissue side of a dental prosthesis, such as dentures, to improve fit and comfort. Over time, changes in the oral structures can occur due to factors like bone resorption and soft tissue changes, causing dentures to become ill-fitting. During the relining procedure, the dentist will apply a new layer of material to the underside of the prosthesis, effectively matching it more closely to the current contours of the patient's gums. This not only enhances the stability of the prosthesis but also helps to prevent irritation and sores that can result from poor fitting. Creating a new dental impression pertains to making a mold of the teeth and soft tissue, which is a separate process from relining. Removing decay from a tooth is involved in restorative procedures rather than adjustments to prosthetic devices. Shaping teeth for braces is part of orthodontics and doesn't relate to the adjustment or improvement of dentures or prostheses. Thus, the definition of relining is distinctly focused on the adjustment of existing dental prosthetics, making the choice of resurfacing the tissue side of a prosthesis the correct answer.
