Types Of Dentures

Dental Implants - Common Questions Answered By Implant Dentist

If you have lost a tooth, it is likely that one of your options is to replace it with a dental implant. Before you decide a course of action, you should consider asking your implant dentist some simple questions:

What is a dental implant?

A dental implant is a titanium metal replacement for a root of a tooth that is surgically implanted in the jawbone by a specially trained implant dentist or oral surgeon. As the body heals for approximately two to six months after the surgery, the bone around the implant fuses to the implant through a process called osseointegration. After the healing phase is complete, the implants are used to anchor crowns, bridges, or dentures. Dental implants are the most natural replacement for a missing tooth.

What does the implant dentist do?

The process should begin with a thorough evaluation of the patient's medical and dental history, and a full clinical examination of the entire mouth and missing tooth area by your dentist. The clinical exam should also include specific X-rays. After assessing the patient, a comprehensive treatment plan can be devised. From that point, implants are surgically placed in the jawbone under local anesthesia. The length of the healing time is based on the quality and quantity of bone, as well as the type of implant placed. After adequate healing is allowed to occur, the implant can be used to support a crown, bridge, or denture.

What happens if the dental implant fails to fuse to the jawbone?

If an implant fails to bond to bone, another implant can immediately be put in its place, usually of a slightly larger diameter. In situations where another implant cannot be immediately placed, the area is allowed to heal for a few months and then another one can be put in the same place.

How many implants should be placed?

This is a question that should be determined during the treatment plan. A good rule-of-thumb is to place one implant for each tooth replaced. Other decisive factors for the number of dental implants needed for success is the quality and quantity of the patient's bone. Equally as important are the existing anatomy of the bone and the financial resources of the patient.

Placing enough implants to restore teeth is vitally important to the long-term success of the restoration. Simply stated, the most costly mistake is to have an implant fail because not enough implants are placed to support the teeth. If the number of implants is limited due to financial constraints of the patient, then the implant treatment should be avoided or the type of restoration must be altered.

When you are more knowledgeable about your implant treatment, you will be able to have more input to give your dentist and better your chances of a successful treatment outcome.

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.
