Evolution of Tooth Implants

Dental implantology has made huge strides in just the past 20 years - but the concept is anything but new.

The idea of a tooth replacement anchored permanently into the jaw has been around since antiquity. Archeologists know the ancient Egyptians tried to implant precious stones into the jawbone where teeth were lost. Half a world away, Mayan ruins in Mexico turned up jawbones with tooth implants carved from seashells.

Tooth loss is one of humankind's most common afflictions - and permanent replacement one of dentistry's fondest dreams. If you have a missing tooth or teeth, you probably understand why.

Fast-forward now from the Third Dynasty to today's dental research labs. Three major research advances - all in the past 15 years - combined to make dental implants practical and workable in a wide range of patients.

Tooth implants substitute the rooting of 32 individual teeth with a few metal anchor posts onto which snaps either an overdenture or a fixed bridge. Investigators found that posts made of the metal titanium were strong, non-toxic over years in the mouth, and biologically compatible.

The next critical discovery was the concept of "osseointegration" - in which the healing jawbone actually grows into the dental implant post. This union is capable of sealing harmful bacteria out of the bone tissue.

Credit the computer revolution with the final critical breakthrough: Computerized Tomography (CT) can be used to develop a model of the jawbone's surface. This eliminates the need for preliminary surgery required to make impressions of the jawbone. For certain patients CT imaging can make tooth implant surgery a one-step procedure.

Teeth implants aren't for everybody. But research technicians have expanded its potential beyond the dreams of - well, certainly Ramses II.

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.
