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.

Mini Dental Implants: A Less Invasive Option?

All dental implants are not the same. Depending on how big the implant itself is, it will be classified as either a standard dental implant or a mini dental implant (sometimes called a denture implant).

Regardless of size, they are all titanium implants that fuse to the patient's jawbone and form the base for replacement teeth.

Two out of three dentists offer dental implant therapy, found a recent survey. One out of five think that regular dental implants are always better than mini dental implants.

However, the majority of dentists think mini tooth implants are good for a variety of patients.

A mini implant is smaller and thinner than a regular dental implant. In addition, mini tooth implants are also considerably more affordable. The mini dental implant surgery is also less invasive, takes less time, and heals faster.

"Mini implants have worked very well for my patients because of their low cost and immediate loading," said one dentist. One way dental implant dentists and prosthodontists use mini implants is to help denture patients.

When a patient's dentures don't stay put, the lower denture can be stabilized with mini dental implants; this is known as denture stabilization. The bottom denture will then snap onto the implants, offering better support and retention.

Mini dental implant surgery can appeal to patients since mini dental implants cost less. "They make dental implants affordable for many," declared one dentist.

"There is seldom an occasion anymore when I can't replace traditional implants therapy with minis," raved another. "I'm so thankful I can now offer a less expensive alternative that still brings a lot of joy to those patients that receive them."

Mini dental implant therapy works well for some patients, but it is not for everybody. "Mini implants are good for patients who don't want or can tolerate regular implants, but failure rates are higher with these minis," said an Arizona dentist.

A patient's dental implant dentist or prosthodontist can help determine the best course of action.
