Replace Tooth

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 Implant Cost: Three-Unit Bridge v. Single Dental Implant

Tooth implants are considered the ultimate dental restoration solution for tooth replacement, especially when only a single tooth needs to be replaced.

Traditionally, the best dental restoration for a single missing tooth was a three-tooth bridge, better known as a three-unit bridge. This type of missing teeth restoration worked by linking three false teeth together. The middle tooth was used to bridge the gap. Even though this type of dental restoration was considered state-of-the-art for many years, it had its limitations.

For instance, the fabrication of a three-unit bridge required the teeth on both sides of the gap to be whittled down to allow for the false teeth to be slipped over the top of the teeth. Because the three teeth were linked together, they could not be cleaned in the same way as normal teeth. In addition, they required special dental cleaning tools in order to maintain healthy gum tissue.

Today, dental implants are the first choice to replace missing teeth and dental restoration. In the case of a single missing tooth, a tooth implant can be placed by the implant dentist in the jawbone area of the missing tooth. The implant will serve as a replacement for a tooth root and an individual dental crown. The total apparatus is referred to as a single-tooth implant crown.

Once in place, the dental implant crown will look, feel and function like your natural teeth. They are cleaned and flossed just like your natural teeth, and best of all, they do not require any special tools to clean around them, like bridges. Although tooth implants will not decay, they require that you maintain impeccable oral hygiene.

Does a Dental Implant Crown Last Forever?

Even though dental scientists are developing advanced materials to create a more durable crown, the old adage "nothing lasts forever" also applies to dental implant crowns. Because each patient is different, dental implant crowns last a varied amount of time depending on the patient.

Dental crowns that were thought to last only 3 to 5 years can last 10 to 20 years if meticulously cared for. On the other hand, dental crowns that should last for ten or more years can last only two years in a mouth that is neglected.

The dental implant cost factor is hard to determine precisely. The bottom line is that no one can tell you how long a tooth implant will last, but if you take excellent care of your mouth and see your dentist every six months, you stand a better chance of extending the life of your dental implants and other dental restorations.

How Does the Cost of a Dental Implant Crown Compare to a Three-Unit Bridge?

The cost of a three-unit bridge can range from $2,000 to $3,000. The cost of single tooth implants is approximately $3,000. If teeth associated with a dental bridge fail due to recurrent decay or periodontal disease, ordinarily, dental restoration must be done on the entire dental bridge and possibly add a new filling or build-up of the teeth.

The cost of any foundations under a new dental bridge will add to the dental restoration and tooth replacement cost. If and when a dental implant crown has to be reconstructed, most likely, it would be due to the wearing away of the dental crown material.

The only dental restoration cost would be for that of a new dental implant crown and would not incorporate any adjacent teeth. The dental implant cost over your lifetime would be much less than compared to a three-unit bridge, and is the most natural replacement for a missing tooth.
