What is the Difference Between Relining and Rebasing Dentures?

Introduction

Dentures are a popular and effective solution for people who have lost their teeth. Over time, however, dentures can become loose or uncomfortable due to changes in the shape of the mouth and gums. This is where relining and rebasing come into play. In this article, we will explore the difference between relining and rebasing dentures, their benefits, and how they can help improve the fit and comfort of dentures.

Understanding Denture Relining

Denture relining is a process in which an additional material is added to the tissue side of the denture to improve its fit. This is commonly done when the gum tissue undergoes changes, such as shrinkage or resorption, which can affect the fit and stability of the denture. Relining helps create a better seal between the denture and the gums, resulting in increased comfort and stability.

The Process of Denture Relining

The process of denture relining involves several steps. First, the dentist will take an impression of the gums and any remaining teeth to create an accurate mold. This mold is then sent to a dental laboratory, where the new material is added to the tissue side of the denture. Once the relined denture is ready, it is carefully adjusted to ensure a proper fit and bite.

Benefits of Denture Relining

There are several benefits to denture relining, including:

Improved fit: Relining helps create a snug fit between the denture and the gums, reducing movement and discomfort.

Enhanced stability: A properly relined denture provides better stability, allowing for easier chewing and speaking.

Reduced soreness: Relining can help alleviate sore spots caused by ill-fitting dentures.

Cost-effective: Relining is a more affordable option compared to getting new dentures.

Understanding Denture Rebasing

While denture relining focuses on improving the fit of the denture, rebasing involves replacing the entire base of the denture. This is usually done when the denture base becomes damaged or worn out, compromising the integrity and function of the denture.

The Process of Denture Rebasing

The process of denture rebasing is more involved compared to relining. It typically requires the removal of the acrylic denture base, while retaining the existing teeth and denture teeth. The dentist then creates a new acrylic base that fits precisely over the remaining teeth, providing a stable foundation for the denture. Once the new base is ready, it is attached to the existing denture, resulting in a more durable and functional appliance.

Benefits of Denture Rebasing

There are several benefits to denture rebasing, including:

Improved durability: Replacing the denture base enhances the overall strength and longevity of the denture.

Better fit: Rebasing allows for a more accurate fit, eliminating any discomfort or movement.

Enhanced aesthetics: The new acrylic base can improve the appearance of the denture, providing a natural and pleasing smile.

Restored function: Denture rebasing ensures that the denture functions properly, allowing for effective chewing and speech.

Conclusion

In summary, denture relining and rebasing are two different procedures used to improve the fit and function of dentures. Reline focuses on adding material to the tissue side of the denture to enhance fit, stability, and comfort, while rebasing involves replacing the entire denture base for improved durability and function. Both procedures offer unique benefits and can greatly improve the overall quality of life for denture wearers.
