Dental Bridges

What Is a Dental Bridge?

A dental bridge is a prosthetic structure used to replace one or more missing teeth. It is composed of artificial teeth (pontics) supported by natural teeth or implants on either side of the gap.

What Is It For?

Dental bridges restore chewing function, improve aesthetics, and prevent the displacement of adjacent teeth. They help maintain the natural shape of the face and contribute to clear speech.

Types of Bridges:

Bridges are essential components in restorative dentistry, providing solutions for individuals who have lost one or more teeth. Each type of bridge serves a unique purpose and is designed to cater to different dental needs and situations. Here, we explore the various types of dental bridges in greater detail.

Traditional Bridge: A traditional bridge is a common type of dental bridge that is anchored to crowns placed on adjacent teeth, which are known as abutment teeth. This method involves the preparation of the abutment teeth, which are reshaped to allow for the placement of crowns that will hold the bridge securely in place. The bridge itself, which can replace one or more missing teeth, is typically made of porcelain fused to metal or all-ceramic materials, providing both strength and aesthetic appeal. Traditional bridges are highly effective for patients with healthy teeth on either side of the gap, as they rely on the stability of these surrounding teeth for support.

Cantilever Bridge: A cantilever bridge is a specialized type of dental bridge that is supported only on one side, making it distinct from the traditional bridge. This design is often used in cases where there are adjacent teeth on only one side of the gap. In this scenario, the bridge is anchored to a single abutment tooth, which bears the entire load of the bridge and the prosthetic tooth or teeth it supports. Cantilever bridges can be particularly beneficial in areas of the mouth where there is limited space or when the adjacent teeth are not suitable for crowns. However, because they exert more force on the supporting tooth, careful consideration and evaluation by a dental professional are necessary to ensure the long-term success of this type of bridge.

Maryland Bridge: The Maryland bridge, also known as a resin-bonded bridge, is a conservative option for tooth replacement that utilizes a porcelain framework bonded to the back of adjacent teeth. This type of bridge is less invasive than traditional bridges, as it does not require extensive reshaping of the abutment teeth. Instead, the framework is typically made of a metal or ceramic material that is bonded to the enamel of the neighboring teeth using a strong dental adhesive. Maryland bridges are particularly advantageous in situations where preserving the structure of the natural teeth is a priority. They are often used in the front of the mouth where aesthetic considerations are paramount, as they can blend seamlessly with the natural teeth.

Implant-Supported Bridge: An implant-supported bridge represents a modern and innovative approach to tooth replacement, providing a sturdy and permanent solution for those who have lost multiple teeth. Unlike traditional bridges that rely on adjacent natural teeth for support, this type of bridge is anchored by dental implants that are surgically placed into the jawbone. These implants serve as artificial tooth roots, providing a strong foundation for the bridge. Implant-supported bridges can replace several missing teeth in a row and are particularly beneficial for patients with significant bone loss or those who prefer not to alter adjacent teeth. The integration of implants into the jawbone offers enhanced stability and durability, allowing for improved function and a more natural feel compared to other types of bridges.

Procedure

The process includes the preparation of abutment teeth, impression taking, temporary bridge placement, and final cementation of the custom bridge. The dentist ensures the bite is correct and the bridge fits comfortably.

Conclusion

Dental bridges are an effective and aesthetic solution to restore missing teeth. With proper care, they can last for many years and significantly improve quality of life.
