Replace a Missing Tooth With a Tooth Implant

Compared to previous generations when tooth loss was common, modern dentistry has made it possible for people to keep their teeth healthy and attractive for their entire lives. But for people who have experienced tooth loss, a full or partial denture has been the answer.

But dentures have drawbacks. Food gets caught under the denture with resulting sore gums. Or a denture can loosen and cause embarrassment.

Today, dental implants can replace missing teeth. Although the concept of a tooth implant is not new, advances in technology have improved the treatment process and the longevity of implants.

Modern day dental implants are made of pure titanium and are surgically inserted in the jawbone. The tooth implant is covered with gum tissue and allowed to heal for three to six months. During this time, the titanium meshes with the bone (osseointegration), becoming part of the jawbone itself. After the gums are healed, the implants are uncovered and permanent tooth replacements are attached to the implants.

Dental implants can be used for single tooth replacements, support for a permanent bridge, or as attachments to anchor a full denture securely to the jaw.

If you think a tooth implant could help you or someone you know chew more comfortably, speak more clearly, or look better, call your dental office for more details.

Implant Dentistry Gives You Better Fitting Denture Implants

The art and science of implant dentistry has advanced rapidly during recent years and new techniques and materials have greatly improved our ability to replace missing tissues with functional and natural-looking artificial prostheses called dentures implants. However, it must be remembered from the outset that no prosthesis or artificial substitute will ever function as well as the original living tissues. Research has shown that the chewing efficiency of experienced denture patients is, at best, less than 20% as efficient as the average chewing efficiency of patients with natural teeth.

Why Is the Lower Complete Denture So Hard to Wear?

Both upper and lower dentures are retained in the mouth by an intimately close fit of the plastic denture base to the gums. The intimately close fit is achieved by a combination of muscle control and suction. Mastering the function of the lower denture is more difficult than learning to use an upper complete denture. By comparison, the lower denture has less stable tissue with which to rest on than the upper denture. The lower denture stays in place largely due to the ability of the denture wearer to control their tongue well enough to hold the denture down while they speak and chew. Therefore, lack of tongue coordination in a lower complete denture wearer can severely affect the patient's ability to wear a lower complete denture.

Bone Loss and Complete Dentures

For various reasons, teeth have to be removed. After tooth removal, the residual bone that is used to support the teeth will then shrink away quite rapidly over the first year because the body knows that the residual bone is no longer needed. The greatest amount of shrinkage occurs during the first year after tooth removal. Research has shown that wearing dentures will accelerate jawbone shrinkage. As the shrinkage of the jawbone support progresses over time, new dentures will need to be fabricated in approximately six to ten years. Because each denture wearer is unique, sometimes the internal surface of the denture needs to be readapted to the gum tissues. This procedure is called a reline.

Lower Complete Dentures and Denture Implants

Some patients are never able to adapt to functioning day-to-day with their complete dentures. Many of these patients do not have adequate bone to stabilize a lower denture. Others never develop enough muscle coordination to learn to chew with their dentures. For many years, dentistry had nothing more to offer patients other than a denture adhesive. Today, such problems can often be managed through the use of implant dentistry. Even with as few as two dental implants, the retention and stability of a lower denture can be greatly increased with denture implants. In fact, the chewing efficiency can also be greatly increased. Some patients have estimated that they regained up to 70% of their original chewing capacity. Overall, patients feel more confident when they are in public because they no longer fear that their dentures will slip or cause them embarrassment with denture implants.
