How implants work
Dental implants are a procedure that replaces a missing tooth's form and its function. If you were to have a dental implant, that implant would support a replacement tooth in the same way that a natural tooth root would support a natural tooth.
The concept of performing dental implants is not new. In fact, it has a history that dates back thousands of years. Egyptian mummies have been found that had gold wire implants in their jawbones. Skeletons in the Americas have been found with dental implants made of semi-precious stones. European skeletal remains have exhibited iron dental implants in the jawbone. In the Middle East as well, skeletons have been found with ivory implants.
Although the methods have obviously changed over time, the concept is still the same. In our modern world, dental implants began in the United States during the early 1900's and have become increasingly more popular, especially with the increasing popularity of the titanium cylinder. Now we see several big implant brand name implants and their variations have been approved for use on us as a public consumer.
Some of the various dental implant options that are available include :
replacing a single tooth that doesn't fit with the other teeth just right so that grinding down or altering adjacent teeth is not necessary
Using them as anchors to support a fixed bridge
supporting loose teeth by being splinted to them
supporting replacement teeth for an entirely toothless jaw
providing stability for a complete denture to eliminate the moving and clicking associated with dentures
You will want to first discuss your needs with your dentist in order to determine if dental implants are a good option for you. As part of the assessment, your dentist may require a complete dental history, x-rays and a thorough examination of your teeth and jaw. This will determine if you are a good candidate for undergoing dental implant surgery. The whole procedure involves three major steps.
1. An implant is surgically placed into the bone. This step is normally performed in the dentist's office with a local anesthetic. After placement of the implant, a waiting period of about 4 months is usually required for the implant to sufficiently heal. During this time, the implants should fuse to the bone by a process known as `osseointegration'.
2. A minor surgery is performed to expose the top of the implant. At this point the dentist will attach the `post' to the implant. The post is what will be the support for either one tooth or a set of teeth. This procedure is also done in the dentist's office and is usually quick and requires only local anesthesia.
3. This phase is called the restorative phase because this is where your tooth will take on form and function. The dentist will take an impression of your tooth and then make a prosthesis that will be attached to the implants. This process will require several visits. However, once this phase is completed, your teeth will look natural and will be strong once again.
The long-term success of your dental implant will depend largely on the quality and quantity of existing bone. That is, the stronger the bone and the more bone available, the greater your chance of keeping your implants strong over the long run. Success will also depend on the quality of work put into your implant. Like with any surgical procedure, it is as much an art as it is a science and individual talent and experience counts for a lot.
Another indicator of long-term success is the quality of materials used in the restoration atop the implant. That is, if the design of the implant crowns or overdentures are constructed poorly, your bite will be off-balance and will reduce the life rate of your implant.
Lastly, the success of your implants will depend greatly on how well you maintain them. Brushing and flossing daily is imperative in order to keep them healthy and strong. You will also want to have your implants professionally cleaned by a hygienist that is trained on how to maintain implants and examined by your implant dentist every three to four months.
In summary, dental implants are an amazing procedure that allows a periodontist, an oral surgeon or an implantologist to implant a fixture into your jawbone that will fuse to the bone and allow them to construct new teeth that will serve the same role as natural, healthy teeth.
