Of all the ways modern dentistry has to replace missing teeth, dental implants are by far the best. There is no tooth-replacement option that will give you a longer-lasting result. Implants also help preserve tooth-supporting bone that naturally deteriorates when a tooth is lost. Loss of bone is one of the major hidden consequences of losing teeth. A dental implant most often takes the form of a small, screw-shaped titanium post that replaces the root-part of a missing tooth. The surgical procedure used to place an implant is actually quite minor and routine, requiring only local anesthesia in most cases. After a healing period, the implant is topped with a lifelike crown custom-made to match your existing natural teeth. Implants have a documented success rate of over 95%, which is significantly higher than any other tooth-replacement option.
How Implants Work
During a minor surgical procedure, your dental implant is inserted directly into the jawbone in the space vacated by the missing tooth. It will then be left to heal for a period of months before the final crown is attached. During this healing period, the implant actually fuses to the bone surrounding it.
Tooth Replacement Options Using Dental Implants
Implants can replace missing teeth in a variety of ways. They can be used to:
Replace One Tooth — When you have one tooth missing, a single implant is inserted into the bone to replace the root part of that tooth; a crown then goes on top to simulate an actual tooth. This treatment choice has the highest success rate, making it the best long-term investment for replacing a single missing tooth. Even if the initial cost is slightly higher than other options, it is the most cost-effective solution over time. An implant will never decay or need root canal treatment, and it feels just like the tooth that was there.
Replace Multiple Teeth — When you have more than one tooth missing, implants provide an ideal replacement mechanism. You don’t even need one implant for every missing tooth. Instead, implant teeth can act as supports for fixed bridgework. For example, if you are missing three teeth in a row, we can place two implants, one on either side of the gap, and a crown in between that has no implant underneath. As a result, you won’t need to use any of your remaining natural teeth as bridge supports, which could weaken them and make them more susceptible to decay.
Replace All Teeth Permanently — Implants can support an entire arch of upper or lower replacement teeth that are fixed into the mouth and are never removed. Sometimes the new teeth can be supported by as few as 4 implants. It’s comparable to the structure of a table, which only needs 4 legs to hold it up. In cases where jawbone density and volume have deteriorated, 5 or 6 implants might be needed to support a row of 10 to 12 teeth. Dental implant replacement teeth protect your jawbone, won’t slip, and should last a lifetime.
Support Removable Dentures — Implants can even make removable dentures more comfortable, effective and healthier to wear. Traditional dentures rest on the gums and put pressure on the underlying bone. This accelerates bone loss so that the jaw shrinks and the dentures slip, particularly on the bottom. But today dentists can attach a removable denture onto implants, transferring that pressure into the bone structure rather than the bone surface. This prevents the dentures from slipping while you eat and speak, and preserves the bone directly beneath them.
Implant Care and Maintenance
There are only two ways an implant can lose attachment to the bone and fail once it has successfully fused: poor oral hygiene or excessive biting forces. Poor oral hygiene and/or a lack of regular cleanings can lead to a destructive bacterial infection called peri-implantitis. Flossing and brushing your teeth on a daily basis, along with regular professional cleanings, can prevent this. Excessive biting forces can come from either a habit of clenching or grinding your teeth, or an insufficient number of implants to handle the forces generated by your bite. You should receive the correct number of implants so this does not happen. And if you have a habit of grinding or clenching your teeth, a night guard will be recommended to protect your implants. After all, implants are a long-term investment in your smile, your health and your well-being, so it’s best to protect your investment.
Implant Bone Grafting
When teeth are lost, the bone that used to surround them begins to melt away or “resorb.” Tooth-supporting bone can also be lost when you have periodontal (gum) disease. If you lose enough teeth and bone, your facial features will sag, giving you a more aged appearance; it can also complicate treatment to replace your missing teeth. Fortunately, with modern bone grafting-techniques, the bone that has been lost can be built up again. This can benefit both your health and appearance by strengthening your jawbone, allowing more effective tooth replacement, and increasing support to your facial features.
Bone grafting is a minor surgical procedure that is normally done in a dental office. An incision is made in your gum to gain access to the bone beneath it, and then grafting material is added. Most often, the grafting material is processed bone minerals around which your body will actually deposit new bone cells. The grafting material itself can come from your own body, but very often it is bone from an animal or human donor that has been treated by a laboratory to make it sterile and safe. It can even be a synthetic substance. Grafting material comes in a variety of forms: powder, granules, putty or a gel that can be injected through a syringe. The graft, which is generally covered by a collagen membrane for optimum bone repair, will act as a scaffold onto which your body will build new bone.
