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.

Teeth Implants, Close Up and Natural - Is Implant Dentistry for You?
Teeth implants are a tooth replacement therapy offering natural-looking options for patients. Dental implants anchor artificial or prosthetic teeth into the jawbone. Their performance is nearly equal to natural teeth, providing a secure and comfortable fit, a natural appearance, and a big dose of confidence for people of all ages.
A tooth implant duplicates the tooth's structure. Dental implants are inserted into the jawbone is made of titanium. This metal does well in the body and rarely causes any reaction in patients. It is the same material that is used in knee and hip replacements.
- The implant is cylindrical in shape, resembling a screw, and may even have a thread-like surface. They're uniquely designed with small holes at the outside surfaces for a very good reason. Like the roots of natural teeth, tooth implants stimulate bone growth. It even fools Mother Nature! Over time, the bone tissue actually grows into the small holes, securing the implant.
- The abutment rests over the metal implant. It's a small piece of metal whose purpose is to connect the prosthesis to the tooth implant.
- The prosthesis is the replacement tooth, a natural-looking crown or bridge (if there are multiple teeth missing). A prosthesis that's used to replace a complete set of teeth can be either fixed or removable. A removable prosthesis can be taken out for easy cleaning; a fixed one can only be removed by the dentist, but usually offers better reliability for chewing.
How Do These Different Teeth Implants Parts Work Together?
Since the tooth implant duplicates the tooth's structure, each part contributes to a natural-like functioning of the teeth. Whether replacing one or more teeth, the process of repair is the same. The teeth implants insertion procedure involves three main steps:
- The first is the surgical insertion of the metal implants.
- This is followed by a second surgery, about three to six months later, to insert the abutment.
- The third step, usually two to four weeks later, is custom-making the prosthesis and attaching it to the abutment. There are typically several adjustments needed until the prosthesis is attached to the abutments.
Once the prosthesis comfortably fits, your future is secure. You'll enjoy comfort, confidence, and security in meeting the world and smiling in a whole new way with your new teeth implants.
