Denture Relining: Comprehensive Guide

Dentures are a common solution for individuals who have lost their natural teeth. However, over time, dentures may become loose or uncomfortable due to changes in the shape of the gums and jawbone. Denture relining is a procedure that addresses this issue by reshaping the underside of the denture to ensure a better fit. This comprehensive guide will explore the process, benefits, types, and maintenance of denture relining.

What is Denture Relining?

Denture relining is a procedure that involves adding material to the inner surface of a denture to improve its fit and comfort. This process compensates for the natural changes in the mouth that occur after tooth loss, such as the shrinking of gums and jawbone. By reshaping the denture base, relining enhances the stability and functionality of the denture, ensuring a snug fit against the gums.

Why is Denture Relining Necessary?

Bone Resorption

After teeth are extracted, the underlying bone begins to resorb, or shrink. This process is known as bone resorption. As the bone resorbs, the gums also shrink, leading to changes in the shape and size of the mouth. Dentures that once fit perfectly may become loose and uncomfortable as a result of these changes.

Gum Tissue Changes

The gum tissue also undergoes changes over time. It can become softer or more resilient, affecting the fit of the denture. Denture relining helps accommodate these changes by adjusting the inner surface of the denture to match the current contours of the gums.

Comfort and Functionality

Loose dentures can cause discomfort, sore spots, and difficulty in eating and speaking. Denture relining improves the fit of the denture, enhancing comfort and restoring proper function.

Types of Denture Relining

There are three main types of denture relining: hard relining, soft relining, and temporary relining. Each type has its specific uses and benefits.

Hard Denture Relining

Hard denture relining involves adding a hard acrylic material to the inner surface of the denture. This type of relining provides a durable and long-lasting solution, making it suitable for most patients.

Procedure:

Evaluation: The dentist examines the denture and the patient’s mouth to determine the need for relining.
Impression: An impression of the mouth is taken using a special material. This impression captures the current shape of the gums.
Relining: The impression is used to create a mold, and a new layer of acrylic is added to the denture base.
Fitting: The relined denture is fitted into the patient’s mouth, and any necessary adjustments are made for comfort and functionality.

Benefits:

Durable and long-lasting
Provides a stable and secure fit
Enhances comfort and functionality

Considerations:

Takes longer to complete compared to other types
May require the patient to be without the denture for a short period

Soft Denture Relining

Soft denture relining involves adding a soft, pliable material to the inner surface of the denture. This type of relining is ideal for patients with sensitive gums or those who experience discomfort with hard relining.

Procedure:

Evaluation: The dentist examines the denture and the patient’s mouth to determine the need for relining.
Impression: An impression of the mouth is taken using a special material. This impression captures the current shape of the gums.
Relining: The impression is used to create a mold, and a soft, pliable material is added to the denture base.
Fitting: The relined denture is fitted into the patient’s mouth, and any necessary adjustments are made for comfort and functionality.

Benefits:

Ideal for sensitive gums
Provides a cushioning effect, reducing sore spots
Enhances comfort and functionality

Considerations:

May need to be replaced more frequently than hard relining
Less durable compared to hard relining

Temporary Denture Relining

Temporary denture relining involves adding a temporary material to the inner surface of the denture. This type of relining is often used as an interim solution until a more permanent relining or replacement can be performed.

Procedure:

Evaluation: The dentist examines the denture and the patient’s mouth to determine the need for relining.
Impression: An impression of the mouth is taken using a special material. This impression captures the current shape of the gums.
Relining: The impression is used to create a mold, and a temporary material is added to the denture base.
Fitting: The relined denture is fitted into the patient’s mouth, and any necessary adjustments are made for comfort and functionality.

Benefits:

Quick and convenient solution
Provides immediate relief and improved fit
Suitable for interim use while waiting for a permanent solution

Considerations:

Not as durable as hard or soft relining
Intended for short-term use only

The Relining Procedure: Step-by-Step

The denture relining procedure involves several steps to ensure a proper fit and optimal comfort. While the specific steps may vary depending on the type of relining, the general process includes:

Initial Consultation:
- The dentist conducts a thorough examination of the denture and the patient’s mouth to assess the need for relining.
- The dentist discusses the patient’s symptoms, concerns, and preferences to determine the most suitable type of relining.
Impression Taking:
- The dentist takes an impression of the patient’s mouth using a special material. This impression captures the current shape and contours of the gums.
- The impression is sent to a dental lab, where it is used to create a mold of the patient’s mouth.
Relining Material Application:
- In the dental lab, the appropriate relining material (hard, soft, or temporary) is applied to the inner surface of the denture base.
- The relining material is shaped and molded to match the impression, ensuring a precise fit.
Curing and Finishing:
- The relining material is cured or hardened, depending on the type used. This step ensures the durability and stability of the relined denture.
- The denture is polished and finished to smooth out any rough edges and enhance comfort.
Fitting and Adjustments:
- The relined denture is fitted into the patient’s mouth to ensure a proper fit.
- The dentist makes any necessary adjustments to optimize comfort, functionality, and stability.
Follow-Up Care:
- The dentist provides instructions on how to care for the relined denture and schedules follow-up appointments to monitor the fit and condition of the denture.
