Replacement Of Missing Teeth With Implant Dentistry

In implant dentistry, devices are used to replace missing teeth. They are made of titanium, an inert metal that bonds with the bone, forming a very tight union called osseointegration. The modern system of dental implants, the endosseous system, is extremely successful and has a 90% to 95% success rate.

The dental implant itself replaces the root of the tooth. It is usually in the shape of a screw or a cylinder. The implant connects to a component (the abutment) that joins the implant to the replacement tooth (the crown).

Dental implants are ideal replacements for teeth. When healthy teeth have to be prepared for crowns or bridges, healthy tooth structure needs to be removed. But if only one tooth is missing, the dental implant can simply replace it without having to sacrifice the adjacent teeth.

Dental implants can also be used to replace many missing teeth. Multiple teeth can be replaced with implant dentistry and can avoid the need for a removable denture. Removable dentures can be hard to get used to. They may have clasps that can be unsightly and put additional stress on the existing teeth. Full dentures may be difficult to wear and may interfere with eating and speaking. People who wear dentures for a long time may have additional loss of the bone that supports the denture. This bone loss can be accelerated by osteoporosis, and eventually dentures may be very difficult to wear if not impossible. Poor-fitting dentures can interfere with proper nutrition and quality of life.

Generally, one implant is needed to replace each missing tooth. In some situations, several implants need to be joined together into a bridge. This adds greater strength to the implant restoration. If there is not enough bone available to replace a whole set of teeth, implants may be used as anchors for dentures. When dentures are supported by implants they can be much more stable and the implants help prevent the deterioration of the bone that supports the denture.

The endosseous system of implant dentistry has been used for over 30 years. They can look and feel like natural teeth, adding comfort and improving the smile of people of all ages.

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.
