Dental implants are medical devices surgically implanted into the jaw to restore a person’s ability to chew or their appearance. They provide support for artificial (fake) teeth, such as crowns, bridges, or dentures.
When a tooth is lost due to injury or disease, a person can experience complications such as rapid bone loss, defective speech, or changes to chewing patterns that result in discomfort. Replacing a lost tooth with a dental implant can significantly improve the patient’s quality of life and health.
Dental implant systems consist of a dental implant body and dental implant abutment and may also include an abutment fixation screw. The dental implant body is surgically inserted in the jawbone in place of the tooth’s root. The dental implant abutment is usually attached to the implant body by the abutment fixation screw and extends through gums into the mouth to support the attached artificial teeth.
Recommendations for Patients
Before choosing dental implants, talk to your dental provider about the potential benefits and risks, and whether you are a candidate for the procedure.
Things to consider:
Your overall health is an important factor in determining whether you are a good candidate for dental implants, how long it will take to heal, and how long the implant may stay in place.
Ask your dental provider what brand and model of dental implant system is being used and keep this information for your records.
Smoking may affect the healing process and decrease the long-term success of the implant.
The healing process for the implant body may take several months or longer, during which time you typically have a temporary abutment in place of the tooth.
After the dental implant procedure:
Carefully follow the oral hygiene instructions given to you by your dental provider. Regularly cleaning the implant and surrounding teeth is very important for long-term success of the implant.
Schedule regular visits with your dental provider.
If your implant feels loose or painful, tell your dental provider right away.
Benefits and Risks
Dental implants can significantly improve the quality of life and the health of a person who needs them. However, complications may sometimes occur. Complications can occur soon after dental implant placement or much later. Some complications result in implant failure (usually defined as implant looseness or loss). Implant failure can result in the need for another surgical procedure to fix or replace the implant system.
Benefits of Dental Implant Systems:
Restores the ability to chew
Restores cosmetic appearance
Helps keep the jawbone from shrinking due to bone loss
Preserves the health of the surrounding bone and gums
Helps keep adjacent (nearby) teeth stable
Improves quality of life
Risks Associated with Dental Implant Systems
Damage to surrounding natural teeth during implant placement
Injury to the surrounding tissues during surgery, such as sinus perforation
Injury during surgery (for example, fracture of surrounding jawbone)
Inadequate function, such as feeling like the teeth do not bite together normally
A sensation that the tooth is loose or twisting in place resulting from an abutment screw loosening
Implant body failure (looseness of the implant body)due to systemic infection, which may be more likely in patients with uncontrolled diabetes
due to local infection in bone and gums supporting the implant body
due to delayed healing, which may be more likely in patients who smoke
Difficulty cleaning the gums around the implant, resulting in poor oral hygiene
Untreated periodontal disease
Post-surgical numbness due to nerve impingement or damage
Always notify health care providers and imaging technicians that you have dental implants before any magnetic resonance imaging (MRI) or x-ray procedures. Dental implants can distort or interfere with these images. FDA is not aware of any adverse events reported for MRI or x-ray procedures with dental implants.
Ways Dental Implants are Evaluated for Safety
Dental implants systems are typically made of materials that follow international consensus standards of the International Organization for Standardization (ISO) or ASTM International. These standards have details of what makes a safe material. Most dental implant systems are made of titanium or zirconium oxide. Other materials such as gold alloys, cobalt-based alloys, titanium alloys, or ceramic materials are sometimes used. The safety profiles of these materials are well-known.
Dental implant systems are evaluated according to international consensus standards. Biocompatibility testing, to show that bodily contact with the device does not cause complications like irritation or allergic reaction, is part of the evaluation that helps ensure the materials in the dental implant system are safe and do not cause adverse effects when implanted in people.
For manufacturers to market dental implant systems in the United States, they must first show the FDA their systems are as safe and as effective as dental implant systems already on the market.
