Did You Know That There Are Two Types of Dental Implants?

Despite improvements in access to oral care, many Americans still suffer tooth loss. According to the National Institute of Dental and Craniofacial Research, adults aged 20 to 64 have an average of 24.92 teeth. If you exclude wisdom teeth, this means that the average adult has lost approximately 4 teeth!

For many years, the only treatments available for people with missing teeth were bridges and dentures. Now, with the rise of dental implants, more people than ever benefit from tooth replacement. Dental implants are replacement roots that provide a fixed foundation for artificial teeth. This article explains why people lose their teeth, how implants can help, and the types of dental implants available now.

Why Do People Lose Their Teeth?

Tooth loss can occur suddenly or over a period of many years. In many cases, losing teeth can be prevented through regular dental visits and preventive treatments. Most annual dental visits include radiography (an x-ray) that shows incipient cavities. In-office fluoride application and other preventive measures are effective treatments for dental caries. An untreated cavity can progress into deep-seated decay that will penetrate the inner chambers of the teeth. When this occurs, you face a greater risk of losing the tooth altogether.

But cavities aren’t the primary way that people lose teeth. Contrary to popular belief, gum disease is the leading cause of tooth loss. If you have experienced gum bleeding and sensitivity, than you may have first-stage gum disease, mild gingivitis. The most advanced stage, known as periodontitis, indicates the presence of infection in the gum tissues. Gum disease often leads to tooth loss as a result of gum recession, which gradually erodes support for the teeth.

Broken teeth are another cause, whether from an accident, chewing on hard foods, or grinding at night. A broken tooth may be minor at first but it requires treatment to prevent the break from extending deep into the tooth’s root. At that point, a root canal procedure may be used to try to save the tooth. Extraction is the last resort, becoming necessary only when infection threatens the surrounding area, or when the tissues around a fractured root become inflamed. Once the tooth has been extracted, the next step to protect your oral health is to replace the missing tooth.

What Types of Dental Implants Are Available?

The term “implant” refers to the fact that the base of your replacement tooth is surgically grounded in the jaw. Implantation is a highly successful procedure and a healthy one as well! Choosing dental implants is the best decision you can make because this replacement option will naturally stimulate bone growth in the jaw, similar to what occurs with your natural teeth!

There are two major types of implants:

• Endosteal. This is the most common dental implant procedure, as it has the best track record for surgical success. The implant is placed in the jawbone and may hold one or more teeth. The implant is made of titanium and generally appears in the shape of a small screw.
• Subperiosteal. This type of dental implant is chosen for patients who lack the bone height necessary for an endosteal procedure. When there is not enough healthy jawbone for an implant or the patient does not want to pursue a bone augmentation procedure, a subperiosteal implant can be placed on top of the bone. This technique is less popular, except when necessary, as it does not stimulate bone growth and has a lower long-term success rate.

Additional Considerations

When the jawbone does not provide sufficient support for an endosteal implant, several techniques can be used to rebuild the bone and restore the jawline. The following procedures are options for patients who wish to receive an implant even though they have bone loss:

• Bone augmentation. Bone additives and growth factors can be used to fortify or regenerate the bone. If the bone augmentation is performed at the same time as the tooth extraction, this helps you heal more quickly. The new bone will replace the graft material, which will be absorbed completely into the jaw.
• Sinus lift. This option involves adding bone below the sinus when the natural bone has deteriorated due to missing upper teeth. The upper back jaw has often been one of the most difficult regions of the mouth to place dental implants because of insufficient bone. Several techniques can be used for sinus surgery, which involves growing the jaw bone and raising the sinus floor. A prosthodontist or student dentist can explain the different grafting options available.
• Ridge expansion. The ridge bone surrounds and supports the teeth. Whenever a tooth is removed, the ridge begins to deteriorate. It can also lose density because of disease or aging processes. Ridge expansion is a procedure used to widen the jaw. Bone graft is added along the bridge to provide the support needed for dental implants.
