What's the Difference Between a Dental Bridge and a Dental Implant?

What is used to get across a gap -- a bridge of course! A dental bridge spans the gap between one or more missing teeth giving you a better smile.

Your teeth not only help you chew and speak correctly, but also contribute substantially to your smile and overall appearance (your teeth give form to your face and without them, your facial features can be significantly affected.) If lost teeth are not restored, other teeth often shift, causing crooked teeth, leading to cavities and gum disease. Dental bridges restore potentially compromised oral health to full function.

What Is a Dental Bridge?

A bridge is a special dental appliance used to restore missing teeth. There are several types of bridges used to span the space. The three most common types include:

• Fixed Dental Bridge - This type of bridge is cemented next to the teeth adjacent to the gap, called the "abutment" teeth. A replacement tooth, called a pontic, is attached to crowns that provide added support and cover the abutment teeth. Fixed bridges can only be removed by the dentist.
• Removable Partial Dentures - When the span is large, your dentist may suggest this type of bridge. A removable partial denture fastens to natural teeth with clasps or attachments. This type of appliance can be removed for cleaning and is less expensive than the fixed type. However, it's usually not as durable as the fixed bridge.
• Dental Implant Supported Bridges - When implants have been placed in spaces that have no teeth, they serve as "abutments" or anchors for a bridge.

What Materials Are Used in a Dental Bridge?

An assortment of materials are available depending on the function and appearance. Porcelain, tooth-colored acrylics, gold alloys, and alloys made from non-precious metals all provide important restorative qualities along with making your smile the way you want it.

What's Involved in the Procedure?

Normally at least two visits are needed for preparing the teeth, custom-designing the bridge, and making adjustments for proper fit and comfort.

How Do I Care for My New Dental Bridge?

With bridges, extra care must be given to your gums and teeth. Bridges add more stress to existing teeth and must be supported by healthy gums. Otherwise, these key teeth are susceptible to decay and affect the bridges.

Brushing twice a day and flossing daily along with regular dental visits are essential to good oral hygiene. Flossing is often easier by using floss threaders that help to remove cavity-causing bacteria between the dental bridge and adjacent teeth.

Because bridges are intricate and sometimes difficult to clean, your dentist might suggest a special instrument that helps in caring for your teeth. Similar in design to professional dental cleaning instruments, it's made of tiny filaments that rotate to "swoosh" into the crevices between the teeth and below the gum line. Ask your dentist about this special cleaning device.

With good oral hygiene, a fixed dental bridge can last eight to ten years or more and provide years of service enhancing your smile and appearance and your oral health.

Implant Dentistry Gives You Better Fitting Denture Implants

The art and science of implant dentistry has advanced rapidly during recent years and new techniques and materials have greatly improved our ability to replace missing tissues with functional and natural-looking artificial prostheses called dentures implants. However, it must be remembered from the outset that no prosthesis or artificial substitute will ever function as well as the original living tissues. Research has shown that the chewing efficiency of experienced denture patients is, at best, less than 20% as efficient as the average chewing efficiency of patients with natural teeth.

Why Is the Lower Complete Denture So Hard to Wear?

Both upper and lower dentures are retained in the mouth by an intimately close fit of the plastic denture base to the gums. The intimately close fit is achieved by a combination of muscle control and suction. Mastering the function of the lower denture is more difficult than learning to use an upper complete denture. By comparison, the lower denture has less stable tissue with which to rest on than the upper denture. The lower denture stays in place largely due to the ability of the denture wearer to control their tongue well enough to hold the denture down while they speak and chew. Therefore, lack of tongue coordination in a lower complete denture wearer can severely affect the patient's ability to wear a lower complete denture.

Bone Loss and Complete Dentures

For various reasons, teeth have to be removed. After tooth removal, the residual bone that is used to support the teeth will then shrink away quite rapidly over the first year because the body knows that the residual bone is no longer needed. The greatest amount of shrinkage occurs during the first year after tooth removal. Research has shown that wearing dentures will accelerate jawbone shrinkage. As the shrinkage of the jawbone support progresses over time, new dentures will need to be fabricated in approximately six to ten years. Because each denture wearer is unique, sometimes the internal surface of the denture needs to be readapted to the gum tissues. This procedure is called a reline.

Lower Complete Dentures and Denture Implants

Some patients are never able to adapt to functioning day-to-day with their complete dentures. Many of these patients do not have adequate bone to stabilize a lower denture. Others never develop enough muscle coordination to learn to chew with their dentures. For many years, dentistry had nothing more to offer patients other than a denture adhesive. Today, such problems can often be managed through the use of implant dentistry. Even with as few as two dental implants, the retention and stability of a lower denture can be greatly increased with denture implants. In fact, the chewing efficiency can also be greatly increased. Some patients have estimated that they regained up to 70% of their original chewing capacity. Overall, patients feel more confident when they are in public because they no longer fear that their dentures will slip or cause them embarrassment with denture implants.
