Maryland Bridge: What It Is, Types & Who Can Get One

TL;DR

• Maryland bridge (also called a resin-bonded bridge) replaces a missing tooth using a metal or porcelain framework that bonds to the backs of the teeth on either side, with no crowns and little to no enamel removal.
• It is most suitable for front teeth in low-bite-force zones and for patients who want a minimally invasive, typically lower-cost option without surgery.
• The trade-off is durability: Maryland bridges can debond over time and are not recommended where significant chewing force is applied.
• Among the four main bridge types, Maryland bridges are the only option that preserves the adjacent teeth entirely, which makes them a practical bridge for patients with healthy neighboring teeth.
• Ideal candidates have good gum health, healthy adjacent teeth with enough enamel surface for bonding, and a missing front tooth rather than a back molar.

What Is a Maryland Bridge Restoration?

Maryland bridge is a tooth replacement option designed for patients who need to fill a single missing tooth gap, particularly in the front of the mouth, without altering the teeth on either side. Unlike a traditional bridge, which requires crowning the adjacent teeth to anchor the replacement, a Maryland bridge uses a thin metal or porcelain “wing” bonded to the back surface of each neighboring tooth. This makes it one of the most tooth-preserving options available for a missing tooth.

If you’ve been researching dental bridges and want to understand where this particular design fits in, here’s a clear breakdown of how it works, where it excels, and where other options may serve you better.

How Does a Maryland Bridge Work?

The Maryland bridge, more formally called a resin-bonded fixed partial denture, was popularized by the University of Maryland in the 1980s, which is how it got its name.

At Anoka Dental, Dr. Rich Capp typically follows these steps during the process:

1. Examination and X-rays to confirm adjacent teeth are healthy and have sufficient enamel surface area for bonding

2. Minimal preparation of the bonding surfaces on the back of the neighboring teeth, typically with no drilling of the front surface

3. Taking impressions or digital scans sent to a dental lab for fabrication

4. Bonding the finished framework with dental resin cement at a second appointment

Because no tooth structure is removed from the front of the neighboring teeth, the procedure is largely reversible, a meaningful consideration for patients who may want to transition to a dental implant later.

What Are the Main Types of Maryland Bridges?

At our dental practice in Anoka, we may recommend different types of Maryland bridges depending on the location of the missing tooth, bite alignment, and overall oral health. The most common types include:

1. Metal-Framed Maryland Bridge

This is the traditional type of Maryland bridge. It uses a thin metal framework with small “wings” attached to the back of the neighboring teeth to hold the replacement tooth in place.

We may recommend this option because it:

• Provides strong support for the replacement tooth
• Requires very little alteration to the surrounding teeth
• Works well for replacing front teeth with lighter biting pressure
• Is generally more affordable than some other restorative options

The metal is hidden behind the teeth, although in some cases, a slight grey shadow may show through certain teeth depending on enamel thickness.

2. Porcelain-Fused-to-Metal Maryland Bridge

This type combines a metal framework with porcelain layered over it for a more natural appearance. It offers a balance between strength and aesthetics.

Patients often choose this option because it:

• Looks more tooth-like than a traditional metal-only bridge
• Blends better with surrounding teeth
• Still offers good durability and support

This can be a suitable choice when appearance is especially important, but additional reinforcement is still needed.

3. All-Ceramic or Zirconia Maryland Bridge

For patients focused on aesthetics, we may recommend an all-ceramic or zirconia Maryland bridge. Instead of metal, the framework is made from tooth-colored ceramic material.

Some advantages include:

• Excellent natural appearance
• No dark metal showing through the teeth or gums
• Better light reflection for a more realistic look
• Ideal for highly visible front teeth

Zirconia versions are also quite strong, making them a popular modern alternative to traditional metal frameworks.

4. Fiber-Reinforced Maryland Bridge

This newer option uses fiber materials bonded with composite resin to support the artificial tooth. It is often used as a more conservative or temporary solution.

We may suggest this type when:

• A minimally invasive approach is preferred
• Younger patients need a temporary replacement
• A quick, cost-effective restoration is needed
• The surrounding teeth are healthy and strong

While fiber-reinforced bridges can look very natural, they may not last as long as ceramic or metal-supported options.

Who Is a Good Candidate for a Maryland Bridge?

A Maryland bridge works best in specific situations where the surrounding teeth and gums can properly support the restoration. Patients who are typically considered suitable candidates often have:

• A single missing front tooth, particularly in the upper or lower anterior region, where bite forces are lighter.
• Healthy adjacent teeth with adequate enamel, where the bonding wings need a clean, sound surface to adhere to; teeth with large existing restorations or decay may not provide sufficient bonding surface.
• Good overall gum health, as gum disease or recession can compromise both the bonding and the long-term fit of the pontic.
• A preference to avoid surgery (ruling out implants) and a desire to preserve the neighboring teeth (ruling out traditional bridges).
• Patients who may want to convert to a dental implant at a later stage, since a Maryland bridge leaves the adjacent teeth intact, and the transition is straightforward.

Patients who are not suitable candidates tend to have heavy bites, bruxism (teeth grinding), or a missing molar where the chewing forces would likely cause debonding. Maryland bridges are also not typically recommended when multiple adjacent teeth are missing, as the single pontic-wing design is not engineered to span larger gaps.

Is a Maryland Bridge the Right Option for Your Missing Tooth?

A Maryland bridge restoration works well for the right patient, but as with any restorative decision, the fit depends on the specifics of your case: which tooth is missing, what the adjacent teeth look like, and how much bite force the area typically handles. The only way to know whether this option makes sense for you is to have a dentist examine the area directly and discuss what each option would actually involve for your mouth.
