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 Implantology

Much is being said about dental implant procedures. A national radio spot states that steak and corn-on-the-cob are no longer just a memory for people with tooth loss. Tooth implants, they say, can bring back bite strength and, certainly, improve all-around dental function.

Just what are dental implants though?

Tooth replacement systems differ but continue to evolve as materials and methods allow. Teeth implants are a great and functional alternative to removable dentures.

An implant device is inserted into the upper or lower jawbone. After a healing period, posts are attached to each implant. And to that, a fixed bridge or "over-denture" is placed by the implant dentist. This is known as the "business end" of the implant. Only the "tooth part" is visible. The result is not new teeth. But for more and more people, tooth implants count plenty as the next best thing.

Why go for it?

Over 42% of people 65 and have a missing tooth or teeth. Dentures work fine in some cases, and not so well in others. In fact, ill-fitting dentures can contribute to the loss of supporting teeth or bone, and aggravate deterioration of your mouth.

Other tooth replacement alternatives?

Well, you could go toothless. But along with that comes a change in eating habits, quality of speech, and level of self-esteem.

"My mouth is me again."

In many dental practices, implant dentists have had great success with "osseointegrated" (osseo = bone) dental implants, a system where bone and implant mesh. As implant research has grown into dental implantology, many types of appliances have been tested (and some discarded). The Branemark implant, a titanium device developed in Sweden, has the longest track record, a 95% success rate over 20 years.

What makes a successful tooth implant?

In the Branemark system, it's the 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. But the real benchmark for the success of a dental implant procedure is this: The patient has to be happy with it. For years.

For certain people, a single implant to bridge a gap is called for. Another person might require two to support a bridge, or two to four implants to stabilize a lower denture. In other people, bone loss is already severe, and what remains cannot support an overdenture, so a tooth implant procedure is not the solution. However, when they work, they're as real as it gets.

If you think you might benefit from teeth implants, call your implant dentist for a consultation.
