Why Dental Bridge Materials Matter

The decision to choose from the various types of dental bridges is driven by the need to fill gaps between teeth left by missing teeth. While the primary goal is to restore functionality and aesthetics, the choice of material used in the dental bridge plays a crucial role in determining its success. This is not just about how the bridge looks but also how well it performs over time, its compatibility with your body, and even how much it will cost. Here are some of the reasons why understanding the different bridge materials is important.
- Biocompatibility and Allergic Reactions:
Dental bridges are considered foreign to the oral cavity. Different materials interact with the human body in various ways, and some are more biocompatible than others. They are less likely to cause reactions or be rejected by the body. - Durability and Strength:
Some materials offer higher durability and greater strength, making them suitable for replacing teeth that receive more force or load. Some materials may not offer durability and strength but are preferred for their aesthetic qualities. - Longevity:
Different materials have different lifespans. Highly durable materials tend to last longer than those that are not as durable. - Aesthetics:
Like any dental treatment, the appearance of the dental prosthesis is important, especially for front teeth. The material chosen can dramatically affect the dental bridge’s natural appearance. Materials like all-ceramic and zirconia are crafted to closely mimic the appearance of natural teeth, making them common choices for patients seeking aesthetics. Metal bridges, while strong, are more unnaturally visible, and might be preferred more for the molars than replacing the front teeth. - Overall success:
The material’s properties can influence the bridge’s ability to withstand daily functions like chewing and speaking. Moreover, some materials are better suited for patients with specific cases, such as metal allergies or bruxism. - Dental bridge cost implications:
The choice of material can also directly impact the dental bridge cost. While offering superior qualities, some materials may have a higher price tag.
Commonly Used Dental Bridge Materials
Dental bridge materials play a crucial role in the success and suitability of dental bridge treatments. These materials influence the aesthetic outcome and impact the durability, comfort, and overall functionality of the bridge. They can affect the treatment process, including the tooth preparation, the dental bridge longevity, and the patient’s comfort. The selection of the right material is one of the key decisions in dental bridge treatment, shaped by factors like the location of the missing tooth, the patient’s overall oral health, and personal preferences. The right decision ensures a good balance between practicality and aesthetics.
- Porcelain-fused-to-metal (PFM) bridges:
Porcelain-fused-to-metal (PFM) bridges offer a commendable balance between the strength of metal and the aesthetic appeal of porcelain. This makes them a versatile and popular option for a pleasing restoration. However, they are not without limitations. However, it comes with the risk of the porcelain chipping or breaking off, exposing the metal underneath. Additionally, there will be a visible grey line along the gum line after some time, as the gum tissue might react to the presence of metal. - All ceramic bridges:
They are highly favoured for their superior aesthetic qualities, particularly for front teeth, where visual considerations are paramount. However, they can be more expensive than other materials and may require extensive preparation of the abutment teeth. - Metal Alloys:
These materials offer exceptional strength and durability, but they have poor aesthetic appeal. The metal does not match the natural teeth, making them more noticeable. However, they are more suitable to replace back teeth where aesthetics are less of a concern. - Acrylic Bridges:
Often used as temporary or provisional bridges, they are less durable and are not recommended for long-term use. However, it is a cheaper alternative and useful for short-term options while waiting for the final bridge.
The Rise of New Dental Bridge Materials
As dental technology advances, new dental materials are being introduced that offer alternative options to traditional choices. These emerging materials come with their own sets of benefits and limitations. Let’s explore some of these newcomers in dental bridge materials.
- Zirconia:
They are strong and durable materials with high aesthetic quality. Zirconia can be matched with natural teeth and is considered biocompatible, reducing the risk of allergic reactions. However, it may be more expensive than other materials. - Fibre-reinforced Composite Bridges:
Fibre-reinforced composite bridges represent a lightweight restoration and a modern alternative in dental bridge fabrication. They can be closely matched to the colour of the natural teeth, offering an aesthetically pleasing result. They have a low risk of allergic reaction, and are recommended for patients with metal allergies. These composite bridges tend to require less tooth removal compared to traditional bridges. They may be strong, but they are not as durable as metal or ceramic bridges, especially in high bite force areas. Lastly, the success of composite bridge treatment highly depends on the skill level of the dentist and techniques used during placement.
The Relevance of Gold in Dental Bridges
While newer materials have been making waves in the dental industry, gold remains a tried-and-tested option for dental bridges with proper care. It may not be as popular as it once was, but it still offers a range of benefits that make it worth considering.
