Implant-Supported Bridges vs. Traditional Bridges: Pros and Cons

As far as lost teeth replacement goes, implant-supported bridges and traditional bridges are among the popular methods. Despite their differences in pros and cons, deciding between the two is usually based on the specific needs of a patient, his or her preferences, and general oral health. In this article we will look at some of the advantages and disadvantages associated with both alternatives which you may consider before making a choice.

What is a Traditional Bridge?

A traditional bridge is a solid dental prosthesis designed to replace one or more missing teeth by being attached to natural teeth on either side. The abutment teeth (the adjacent ones) are often trimmed down to serve as crowns that hold the bridge in place, while the pontics (replacement teeth) fill the space created by the missing ones.

Pros of Traditional Bridges:

• Quick Procedure: One of the primary benefits of this type of bridge is its quick procedure, as it can be completed in just two visits to the dentist’s office. This makes it appealing for people who want a fast remedy for their tooth loss problem.
• Low Initial Cost: Compared to implant-supported bridges, traditional bridges are relatively inexpensive upfront, making them affordable even for patients with limited financial resources.
• Proven Track Record: Traditional bridges have been used successfully for many years, and they are considered a widely accepted method for replacing missing teeth.
• No Need for Surgery: Unlike dental implants, traditional bridges do not require surgery. For patients who may not be suitable candidates for surgical procedures due to underlying health problems or who prefer to avoid surgery, this is an added advantage.

Cons of Traditional Bridges:

• Alteration of Healthy Teeth: The major disadvantage of traditional bridges is that healthy adjacent teeth must be modified in some way. These natural enamel structures must undergo reduction to fit the bridge’s supporting crowns. This process compromises the strength of these teeth, and it cannot be reversed.
• Limited Lifespan: Depending on the quality of the bridge, the patient’s oral hygiene, and the materials used, traditional bridges typically last between 5 and 15 years. This means that at some point, the bridge may need to be replaced or repaired, which incurs additional costs.
• Potential for Decay and Gum Disease: Because traditional bridges are connected to natural teeth, there is a risk of decay or gum disease developing around the abutment teeth. This can compromise the stability of the bridge and lead to further oral health issues.
• Bone Loss: Traditional bridges do not address the issue of bone loss in the jaw. Over time, decreased bone density may occur due to the lack of stimulation from the roots of the missing teeth. This can eventually lead to facial deformities, such as a sagging chin.

What is an Implant-Supported Bridge?

An implant-supported bridge is a prosthetic dental device that is attached to dental implants rather than being fixed onto natural tooth structures. A small titanium post, known as a dental implant, is surgically inserted into the jawbone, where it acts as an artificial root for tooth replacement. After the implant is placed, a dentist attaches a crown to it, providing the stability needed for chewing hard foods.

Implant-Supported Bridges: The Advantages

Preservation of Healthy Teeth: One of the main advantages of implant-supported bridges is that they do not require adjustments to the healthy teeth adjacent to them. The bridge is anchored to implants rather than natural teeth, leaving all remaining teeth in the area untouched.

Long-Term Durability: Implant-supported bridges are well known for their longevity. With proper care, this type of construction can last for 20 years or even longer, making it a long-lasting and reliable solution for replacing missing teeth.

Prevention of Bone Loss: Like natural tooth roots, dental implants stimulate the jawbone, helping to prevent bone loss. This is crucial as it maintains the integrity of the jaw and prevents facial deformities that can result from a reduction in bone mass.

Improved Functionality: Compared to conventional bridges, implant-supported bridges are more stable and offer greater biting functionality since they are securely fixed into the bone. Many patients find that they feel more comfortable eating, speaking, and smiling confidently with an implant-supported bridge.

Aesthetic Advantages: In terms of appearance, implant-supported bridges are more aesthetically pleasing because they blend seamlessly with the existing teeth. Additionally, they help preserve the original facial structure by preventing bone shrinkage.

Implant-Supported Bridges Drawbacks:

Higher Initial Cost: Implant-supported bridges typically cost more than traditional dental bridges. This investment includes the costs related to purchasing the implants, their surgical installation, and acquiring the necessary bridge unit itself. However, it’s important to note that these expenses may be offset by the long-term durability and lower maintenance requirements of implant-supported bridges.

Surgical Procedure Required: The placement of dental implants involves surgery, which carries risks such as infection, anesthesia complications, and nerve damage. Some patients may not be able to undergo this procedure due to medical reasons.

Longer Treatment Time: It takes longer to receive an implant-supported bridge compared to a regular bridge. There is a waiting period of several months after the implants are placed before the bridge can be attached. This extended timeline may be a disadvantage for those seeking a quicker solution.

Bone Density Requirements: Not every patient qualifies for dental implants. Adequate bone density in the jaw is essential for successful implantation. If there is preexisting bone loss, a bone grafting procedure may be necessary, which adds additional time, cost, and complexity to the treatment process.

Choosing the Right Option

Making a choice between an implant-supported bridge and a traditional bridge depends on various factors such as oral health, personal preference, and budget. Here are some considerations:

Oral Health: An implant-supported bridge may be the better option if your adjacent teeth are healthy and you want to keep them that way. It does not require any alterations to intact teeth and is the most durable option.

Budget: If you have budget constraints, a traditional dental bridge might be more affordable upfront. However, keep in mind that maintenance and replacement costs could be higher over time.

Timeline: If you need a quick solution, a traditional bridge offers a faster option. However, if you’re willing to wait for a more lasting solution, an implant-supported bridge might be worth considering.

Bone Health: Implant-supported bridges are ideal when there is adequate bone density and they help prevent further bone loss. If bone density is a concern, consult your periodontist about bone grafting or other therapies that can be done.

Comfort and Functionality: For those who prioritize stability, comfort, and functionality, implant-supported bridges generally provide better results. They feel more like natural teeth and offer superior performance in chewing and speaking.

To Conclude

There are pros and cons to both implant-supported bridges and traditional bridges. Traditional bridges are quicker to complete and more cost-effective, but they involve altering healthy teeth, which may not be ideal for long-term concerns like bone loss. On the other hand, implant-supported bridges provide a more durable, stable, and natural-looking solution, but they come with higher treatment costs and longer, more complex procedures.

It is advisable to consult with Dr. Baroudi, who has extensive experience in this field, to help you weigh the advantages and disadvantages based on your specific situation. Understanding the differences between these two options will enable you to make an informed choice for your oral health needs. Whether you choose an implant-supported bridge or a traditional bridge, both options are crucial for addressing missing teeth, maintaining a healthier oral life, and preserving the beauty of your smile over time.
