What are Fixed Dentures?

Fixed dentures, also known as fixed bridges or implant-supported dentures, are a permanent tooth replacement solution for missing teeth. Unlike removable dentures, they are cemented into place and cannot be taken out by the wearer. This provides a stable and secure fit, offering a more natural feel and function compared to removable options. They offer a robust and long-lasting solution for restoring your smile and chewing ability.

Types of Fixed Dentures

There are several types of fixed dentures, each suited to different situations and needs:

1. Traditional Fixed Bridges

These are the most common type of fixed denture. They're supported by the adjacent teeth, which are prepared by being crowned or capped. A prosthetic tooth, or pontic, is attached to these crowns, bridging the gap where the missing tooth used to be. This is a cost-effective solution when healthy adjacent teeth are present.

2. Implant-Supported Dentures

Implant-supported dentures use dental implants to anchor the denture. These implants are surgically placed into the jawbone, acting as artificial roots for your new teeth. This offers superior stability and bone preservation compared to traditional bridges. This type is ideal for individuals with missing teeth and sufficient jawbone density.

3. Maryland Bridges

Maryland bridges use metal or porcelain wings that bond to the back of adjacent teeth. This is a less invasive option than traditional bridges, requiring minimal preparation of existing teeth. However, it may not be suitable for all situations due to its reliance on the strength of adjacent teeth.

4. Cantilever Bridges

These bridges are supported by only one side, making them suitable for replacing a single tooth at the end of a tooth row. They are less common than other types of fixed bridges due to the increased stress placed on the supporting tooth.

The Fixed Denture Procedure

The procedure for getting a fixed denture varies depending on the type chosen. Here's a general overview:

1. Consultation and Examination

The dentist will assess your oral health, jawbone structure, and the extent of tooth loss. This is crucial for determining the best type of fixed denture for your needs. X-rays and impressions may be taken.

2. Tooth Preparation (if applicable)

For traditional bridges, adjacent teeth need to be prepared by reducing their size to accommodate crowns. For implant-supported dentures, surgical placement of the implants is necessary. This often involves a period of healing before the final denture is fitted.

3. Impression Taking

Precise impressions are taken of your teeth and gums to create a custom-fitting denture.

4. Denture Fabrication

A dental lab crafts the fixed denture based on the impressions taken. This process can take several weeks.

5. Placement and Cementation

Once the denture is ready, it is cemented permanently into place.

Benefits of Fixed Dentures

Improved Aesthetics: Fixed dentures restore a natural-looking smile, improving your confidence.
Enhanced Function: They restore chewing ability and speech clarity.
Increased Stability: They are firmly fixed in place, unlike removable dentures.
Better Bone Preservation (Implant-Supported): Implants stimulate bone growth, preventing bone loss.
Long-lasting: With proper care, fixed dentures can last for many years.

Costs of Fixed Dentures

The cost of fixed dentures varies greatly depending on several factors including the type of denture, the number of teeth replaced, the materials used, and the dentist's fees. It’s essential to get a personalized quote from your dentist.

Aftercare for Fixed Dentures

Maintaining good oral hygiene is essential for the longevity of your fixed dentures. This includes:

Brushing twice daily: Use a soft-bristled toothbrush and fluoride toothpaste.
Flossing daily: Use floss threaders to reach under the denture.
Regular dental checkups: Visit your dentist for regular cleanings and examinations.
Avoid hard foods: Protect your dentures by avoiding excessively hard or sticky foods.

Frequently Asked Questions about Fixed Dentures

Q: How long do fixed dentures last?

A: With proper care, fixed dentures can last for 10-15 years, or even longer in some cases. Implant-supported dentures generally have a longer lifespan than traditional bridges.

Q: Are fixed dentures painful?

A: The procedure may involve some discomfort, but most dentists use local anesthesia to minimize pain. Aftercare may involve some mild soreness, but this usually subsides quickly.

Q: What are the alternatives to fixed dentures?

A: Alternatives include removable partial dentures, full dentures, and dental implants. The best option depends on individual needs and circumstances.

By understanding the different types, procedures, and aftercare requirements, you can make an informed decision about whether this treatment is right for you.
