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.

Dental Implants: Spare Parts, Small Miracles

In spite of the tremendous reduction in dental cavities in the past 20 years, a missing tooth or teeth remain a problem in the adult population. The sheer numbers of tooth loss in people over 35 indicate many of us could benefit from dental implants.

Tooth implants have been part of many dentist practices for over 20 years. The success rate has been, and continues to be, over 95 percent.

Many people are now considering using implants to replace one tooth, or all their missing teeth. Many adults with missing teeth have partial or complete dentures and bridges, and they work fine.

However, conventional prostheses may not do for everyone - the patient may have trouble with a removable denture or is otherwise unable to chew. These are the very people who could stand to benefit most from as a few as two teeth implants.

How does the dental implant procedure work?

A root-form tooth implant is inserted into the upper or lower jawbone. After a healing period of a few months, posts are attached to each implant. Then a fixed bridge or overdenture is placed - the business end of the implant. Only the tooth part is visible.

For certain people, a single tooth replacement to bridge a gap is called for. Another patient might want to stabilize a lower denture.

The procedure is no more uncomfortable to the patient than a simple tooth extraction.

The success of the new dental implants is due to osseointegration, the meshing of implant and bone. The properties of the implant are such that a chemical and mechanical bond is formed. The jawbone actually grows into the implant. This contributes to the stability and comfort of the implant - and a patient rediscovering the joys of steak and fresh apples.
