Everything You Need to Know About Denture Relines and Rebases

Dentures are a lifeline for many, restoring not just smiles but also the ability to speak and eat comfortably. However, as time passes, the fit of your dentures may change, leading to discomfort or difficulties in daily activities. This is where denture relines and dentures rebasing come into play. In this comprehensive guide, we'll explore what denture relining and rebasing entail, why they're essential, and how they can significantly improve the comfort and functionality of your dentures. Whether you're a denture wearer or a dental professional, understanding these processes is crucial for optimal denture care.

What Is a Denture Reline?

A denture reline involves adding new base material to the tissue side of the denture to ensure a snug fit against your gums. Over time, the gums and bone structure in the mouth change, causing dentures to become loose. Relining adjusts the denture base to the current shape of your mouth without altering the denture teeth that are in good condition.

Types of Denture Relines

There are two primary types of denture relines:

• Soft Reline: This involves using a softer, pliable material to reline the denture, providing a cushioning effect for sensitive gums.
• Hard Reline: Utilizes hard acrylic material similar to the original denture base, offering a more durable solution.

Why Do Dentures Need Relining?

Wearing dentures for extended periods can lead to changes in the gum tissue and bone structure due to resorption. This process makes the gums shrink, resulting in ill-fitting dentures that may cause sore spots or instability. A denture reline is an attempt to adapt the inside of the denture to the current shape of your gums, enhancing comfort and functionality.

Understanding Denture Rebasing

Denture rebasing involves replacing the entire acrylic denture base material without changing the arrangement of the denture teeth. This process is ideal when the denture base is worn out or damaged, but the teeth are still in good condition.

When Is Denture Rebasing Necessary?

Consider denture rebasing if:

• The denture base material is cracked or weakened.
• The denture is broken, but the denture teeth are in good condition.
• You desire to replace the old acrylic base with a new one for hygiene reasons.

What's the Difference Between Denture Relining and Rebasing?

While both processes aim to improve the fit of dentures, they differ in scope:

• Relining: Adjusts the existing denture base by adding new material to the tissue side.
• Rebasing: Replaces the entire denture base with new material, retaining only the existing denture teeth.

Understanding the difference helps in determining the best option for restoring the functionality and comfort of your dentures.

How Is a Denture Reline Performed?

The denture reline procedure typically involves:

1. Impression Taking: Your dentist takes an impression of your mouth using an impression material inside your existing denture.
2. Lab Work: The denture, along with the impression, is sent to a dental lab.
3. Processing: A lab technician adjusts the denture by adding new acrylic material to the tissue side, ensuring a snug fit.
4. Finishing: The relined denture is polished and returned to you, fitting more comfortably in your mouth.

The Role of Dental Labs in Denture Relines and Rebases

Dental laboratories play a crucial role in the relining and rebasing processes. Skilled technicians work meticulously to adjust or recreate the denture base, ensuring that the existing dentures fit perfectly. They use precise techniques to border mold the denture, enhancing its stability and comfort.

The Benefits of Soft Denture Relines

A soft denture reline offers several advantages:

• Comfort: The soft material cushions sensitive gums, making wearing dentures more comfortable.
• Adaptability: Especially beneficial for those with tender gums or who have experienced rapid gum resorption.
• Temporary Solution: Can be used as an interim measure before a new denture is made.

When Should You Consider Denture Rebasing?

Rebasing is appropriate when:

• The denture acrylic base is significantly worn or damaged.
• Replacing the denture base material is necessary for hygiene.
• You prefer not to alter the teeth arrangement but need a sturdier base.

Maintaining the Fit of Your Dentures

Regular maintenance is key to ensuring the stability of your dentures. Here's what you can do:

• Regular Check-ups: Visit your denture clinic or dentist regularly to assess the fit and condition of your dentures.
• Proper Cleaning: Maintain good denture care by cleaning them daily to prevent bacterial buildup.
• Monitor Changes: Be alert to any discomfort or looseness, which may indicate the need for a reline or rebase.

Denture Care Tips for Long-Lasting Comfort

To keep your dentures in optimal condition:

• Handle with Care: Avoid dropping your dentures as they can crack.
• Daily Cleaning: Use a gentle brush and non-abrasive cleaner.
• Soak Overnight: Keep your dentures moist to maintain their shape.
• Regular Adjustments: Relining or rebasing the denture is part of routine denture maintenance.

How Do Relines and Rebases Impact Denture Fit?

Both procedures significantly impact the fit of dentures:

• Relines provide a better suction fit by adjusting the tissue surface.
• Rebases offer a sturdier base when the original has deteriorated.

These adjustments make dentures more comfortable, improving your overall oral health.
