ImplantOverdenturesaMarriageofOptionsforLowerJawToothReplacement

For well over a century, removable dentures have been the main treatment option for patients suffering from severe or total edentulism (loss of teeth). In recent years, however, the dental implant has been recognized as the best option because it can provide patients with permanent tooth replacement, and even more so as implant technology continues to advance.

But while permanent tooth replacement using implants offer more comfort and a better fit than dentures, they are more expensive, sometimes out of the financial reach of many patients. There is, however, one alternative for the lower jaw that blends the two options for tooth replacement into one. This alternative is known as an implant overdenture.

The implant overdenture begins just as a fixed dental implant would: we surgically implant two titanium posts into the lower jaw and allow them to fuse with the bone over time (thanks to the unique way that bone interacts with titanium). But rather than next affixing a porcelain crown to the post as we would with a dental implant, we would instead fashion a denture that fits over the two posts (hence the term overdenture). The overdenture has receiver sites that connect securely with the titanium posts to hold the overdenture in place. This ensures a snug fit with no slippage — resulting in better ability for the wearer to chew food and speak — and without the continuous need for dental adhesive. And just as with traditional dentures, you can remove the overdenture for cleaning.

It might also be an optimal solution for patients with severe issues involving bone loss or compromised teeth that make it difficult for them to support either a fixed prosthesis or a traditional removable denture.

This option does have some drawbacks: since it's still a removable denture, it can still move during meals and food can sometimes get underneath it, which can be annoying. Also, overdentures for the upper jaw require more than two implants because the upper bone is less dense; thus because of a greater number of implants, an upper overdenture is more costly than a lower one.

In the end, an implant overdenture to the lower jaw might be an optimal solution for you — financially and practically — to restore function from severe or total edentulism.

BoneGraftingforDentalImplants

Dental implants are a great choice for many people who need to permanently replace a missing tooth. Reliable and long-lasting, they offer a highly successful outcome, and can even help reduce long-term bone loss and damage to adjacent teeth. One of the best features of implants is that the titanium metal of which they're made actually becomes fused with your natural, living bone tissue.

But sometimes, an examination may show that where you have missing teeth, you may not have enough bone remaining to properly place an implant. Does this mean you're out of luck? Not necessarily!

Employing the refined techniques of bone grafting, regenerating bone tissue has become a standard procedure in periodontal and oral surgery. In many cases, it's possible to build up just the right amount of bone using a variety of grafting materials, in combination with other special techniques. This can enable patients who wouldn't otherwise be good candidates to enjoy the benefits of dental implants.

How does it work? Basically, by helping your body repair itself.

You may already know that bone is a living tissue, which can respond to its environment positively (by growing) or negatively (by resorbing or shrinking). When you've lost bone tissue, the trick is to get your body to grow more exactly where you want it. Once we know where — and how much — replacement bone is needed, we can place the proper amount of bone grafting material in that location. Then, in most cases, the body will use that material as a scaffold to regenerate its own bone.

Bone grafting is often done at the time of tooth removal as a preventive procedure or prior to the placement of an implant, to give the body time to re-grow enough of its own tissue. The procedure is generally carried out under local anesthesia, or with the aid of conscious sedation. Sometimes, if there is enough natural bone to stabilize it, it's even possible to place an implant and perform a bone graft at the same time.

So if you're considering dental implants, let us advise you on what's best for your particular situation. We have the knowledge and experience to help you make the right choices, and achieve the most successful outcome.

UnderstandingTheTypesOfDentalImplantsAndRestorations

Thanks to technological advances, today there are more than 40 types of traditional or standard implants. A traditional dental implant actually replaces the root of a tooth, upon which a crown is built — the part you see in the mouth. There are 2 others types that are quite similar to standard implants. Mini implants are most like traditional implants except they are smaller in diameter. Micro-mini implants are an even smaller variation with an even narrower, more screw-like appearance. Micro-mini implants are also designed to be used on a temporary basis, thus can easily be removed. Together all of these types of implants provide us with a wide variety of options for permanently replacing missing teeth.

The following list details the types of implant restorations:

  • Single tooth replacements: As the name suggests, these implants are used to replace single teeth.
  • Multiple tooth replacements: Implants can be used to replace multiple teeth in a variety of ways. This includes acting as bridge supports to permanently replace missing teeth.
  • Combinations of fixed and removable bridgework: Dental implants can be used to support permanently fixed in teeth, bridgework or removable bridges or dentures. Their biggest advantage over dentures alone is that they stabilize the dentures and preserve the jawbone to which they attach, thus preventing the jawbone from melting away under the pressure of dentures.
  • Over-dentures: These restorations are now considered the new gold standard. In this application two or more standard implants (or multiple mini-implants) are used to attach and stabilize full dentures. Over-dentures are especially useful for tooth replacement in the lower jaw, where denture stability is often problematic.
  • Temporary Anchorage Devices (TADS): These special implants are a tool that orthodontists can use to obtain a stable, non-movable anchor for moving teeth more quickly and easily. They are small, easy to place and easy to remove once their job is done.
  • Temporary bridgework: In this case, mini-implants are used to support temporary bridgework. They are placed between permanent implants and later removed when the permanent implants have healed and teeth are permanently placed on them. Mini-implants ensure that a person is never without teeth during the process of teeth replacement.

NotJustFillingintheGapsLostTeethHaveUnexpectedConsequences

Why is it important to replace missing teeth with restorations such as dental implants? You might be surprised to find that the damage caused by missing teeth is much greater than the simple gaps left in your smile.

As the years go by, teeth lost early in adulthood cause structural changes in a person's face. By age 45 changes in facial structure are already visible in the form of sunken cheeks. By 60, cheeks and lips lose their support, resulting in an aging look. This process continues and if the teeth are not replaced, much of the structural support of the person's face is lost.

These changes are caused by loss of bone. Although it may seem static, bone is actually living tissue that needs constant stimulation to maintain its form and density. With normal stimulation it is in a constant state of resorption (breaking down) and deposition (building up). Teeth provide the needed stimulation for the bone that surrounds them (called alveolar bone) as they meet each other during biting, chewing, and speech. When the stimulation continues, the bone continues to rebuild itself. Without this stimulation, the bone resorbs, does not build up again, and loses substance.

Without stimulation, alveolar bone loses width, height, and volume. Since your teeth and their surrounding bone support your chin, cheeks, and lips, this has a powerful effect on your appearance. It may also affect your ability to chew and to speak.

As alveolar bone diminishes, the next layer of bone also begins to resorb. This is the bone of the jaw itself. The lower part of the face begins to collapse, and the cheeks become hollow. This effect is especially noticeable for people with no teeth (edentulous).

Usually the first tooth to be lost, due to infection and decay, is a molar (back tooth). In the past, a missing single back tooth was frequently replaced by a fixed partial denture (FPD). A crown is provided for each of the two teeth on the sides of the gap, called abutment teeth, to support a false tooth in the middle. However, if they are not well cared for, the abutment teeth may be the next to succumb to decay.

Today the treatment of choice is an implant. A dental implant is a tooth-root replacement made of titanium, which fuses with the bone — making it very stable. Above the gums it is covered by a crown that looks like a natural tooth. The benefit of the implant is that it continues to provide stimulation to the alveolar bone, preventing bone loss.

Implants are also a good choice in the case of multiple missing teeth. They can be used to support bridges or false teeth (dentures). The results are an improved, younger appearance and better functionality.

FAQs About This New and Miraculous Procedure

How can sinus surgery contribute to the replacement of missing back teeth with dental implants?
Dental implants must be anchored the in bone to be successful. Maxillary sinus surgery can help regenerate bone that has been lost and is critically needed to anchor dental implants.

What are the maxillary air sinuses?
Inside the upper jaw, or “maxilla,” are structures known as the maxillary air sinuses, one on either side of the upper jaw. Each sinus is an air-filled space lined by a membrane. Upper back teeth are normally encased in the bone of the maxilla, below the sinuses.

Why is it important to replace missing back teeth?
Replacing back teeth restores the ability to eat, chew, and talk properly. The back teeth also provide facial and cheek support.

Why use dental implants?
Dental implants are the state-of-the-art method for replacing missing teeth.

Why does bone loss occur?
Unless special precautions are taken to prevent it, when teeth are lost, the bone supporting them is also lost.

If there is insufficient bone to anchor dental implants, what are the alternatives?
If all the back teeth are lost and dental implants cannot be placed, removable upper dentures may be the only alternative.

How do you determine whether a sinus surgical procedure is necessary?
The size, shape, and remaining bone of the maxillary sinuses influence whether you can have dental implants with or without a sinus surgical procedure.

How does surgery grow bone?
A small window is created in the sinus wall above where implants need to be placed. The sinus membrane is lifted and the space thus created filled with bone grafting and biologically active bone generating materials. The window is then closed and simply heals.

How is the surgery done?
The surgical procedures are performed from inside the mouth in the area just above the missing back teeth. They are generally carried out under local anesthesia (small shots, just like for a filling), sometimes with the addition of sedation or anti-anxiety medication.

How do bone grafts work?
Bone grafts act as scaffolds that the body replaces with its own bone. The most well researched bone substitute grafting material is currently bovine (cow) bone. All grafting materials are approved by the Food and Drug Administration. They are specially treated to render them completely sterile, non-contagious, and free of rejection factors.

What can I expect after surgery?
Moderate swelling and discomfort after surgery generally lasts for a few days to a week, about the same as having an upper impacted wisdom tooth removed. Supportive treatment usually includes a course of antibiotics to prevent infection and prescription strength medication of the aspirin or ibuprofen type. A decongestant may also be prescribed, if necessary. Healing is generally uneventful.

Who performs this surgery?
Maxillary sinus augmentations are usually carried out by oral surgeons, periodontists, or appropriately trained general dentists. Proper assessment of your situation and diagnosis are critical pre-requisites to the right procedure.

If you are missing upper back teeth, contact us today to schedule an appointment and discuss maxillary sinus augmentation. You can also learn more about this procedure by reading the Dear Doctor magazine article “Sinus Surgery: Creating Bone for Dental Implants out of Thin Air.”
