Different Types of Dental Bridges and Their Methods

Dental bridges are a popular restorative solution designed to "bridge the gap" caused by missing teeth, restoring functionality and aesthetics to your smile. With advancements in dental technology, various types of dental bridges can meet your individual needs and preferences. In this article, we’ll explore the different types of dental bridges and methods used for their placement during a dental procedure.

What Are Dental Bridges?

Dental bridges are prosthetic devices used to replace one or more missing teeth. They are either anchored to the teeth on either side of the gap, known as abutment teeth, or secured using dental implants. The false tooth or teeth in the middle of the bridge, called the pontic, are customized to look and function like your natural teeth.

Bridges will also prevent surrounding teeth from shifting into the gap, which can cause misalignment and other oral health issues. They can also improve your ability to chew and speak.

The Four Main Types of Dental Bridges

There are four primary types of dental bridges, including:

Traditional Dental Bridges
Traditional bridges are the most common type and are used when there are healthy natural teeth on both sides of the gap. The structure for this type of dental bridge includes a pontic supported by crowns placed over the abutment teeth. They are highly durable and suitable for restoring molars and other areas exposed to significant chewing pressure.

Cantilever Bridges
Cantilever bridges are used when there is only one adjacent tooth available to support the bridge. Instead of being anchored to two teeth, the pontic is secured by a crown on a single abutment tooth. This type of bridge lacks support on both sides, so they are typically recommended for the front teeth.

Maryland Bridges (Resin-Bonded Bridges)
Maryland bridges offer a minimally invasive alternative to traditional bridges. Instead of requiring crowns on the abutment teeth, the pontic is supported by a metal or porcelain framework bonded to the back of the adjacent teeth. While Maryland bridges preserve more of the natural tooth structure, they are also less durable and better suited for replacing front teeth.

Implant-Supported Bridges
Implant-supported bridges are a modern and long-lasting solution for patients missing multiple teeth. Rather than relying on natural teeth, these bridges are anchored to dental implants surgically placed in the jawbone. This type of bridge provides superior stability and functionality but the process is more time-intensive and requires adequate bone density to support the implants.

Methods for Placing Dental Bridges

The placement of dental bridges varies depending on the type chosen. Here’s a step-by-step look at the process:

1. Preparation of Adjacent Teeth
   For traditional and cantilever bridges, the abutment teeth are reshaped to accommodate the crowns that will support the bridge. A portion of the enamel is removed to ensure a snug fit. In contrast, Maryland bridges require minimal preparation since the framework is bonded directly to the back of the teeth.
2. Use of Dental Implants
   For implant-supported bridges, the dentist surgically places titanium implants into the jawbone at the site of the missing teeth. Once the implants integrate with the bone, the bridge is then attached to the implants for a secure fit.
3. Impressions and Fabrication
   Once the teeth or implants are prepared, your dentist will take impressions or utilize digital scans to create a mold of your teeth. These impressions are sent to a dental lab, where the bridge is custom-made to match the shape, size, and color of your natural teeth.
4. Final Fitting and Adjustments
   When the dental bridge is ready, your dentist will carefully fit it in place and make any necessary adjustments to ensure proper alignment and bite.

Pros and Cons of Each Type of Bridge

Each type of dental bridge has its advantages and drawbacks:

• Traditional bridges are highly durable but require significant alteration of the abutment teeth.
• Cantilever bridges are less invasive but may not withstand heavy chewing forces.
• Maryland bridges preserve natural tooth structure but are prone to loosening over time.
• Implant-supported bridges offer exceptional stability and longevity but require surgery and a longer treatment timeline.

Your dentist will recommend the best option based on your oral health, the location of the missing teeth, and your budget.

Maintenance and Care for Dental Bridges

Regardless of the type of dental bridge you choose, proper care is essential to ensure its longevity. Regular brushing and flossing are crucial to prevent plaque buildup around the bridge and supporting teeth or implants.
