According to the American Dental Association, there are two distinct types of dental implants currently available your dentist might use for you. Endosteal, which goes directly into your jawbone and Subperiosteal, which sits just below the gums and on top of the jawbone. These are considered to be the safest dental implants today. Both are made of titanium.
Provided your gums are properly taken care of using good oral hygiene, your implants should last you for a lifetime.
There are, however, a few reasons an implant might need to be replaced. These include:
Improper implant placement
Lack of implant gum tightness around the implant
Loose abutment screws
Dental implant site infection
If you find an inflammation of the dental implant site, you may have developed an oral infection called Periimplantitis. When Periimplantitis occurs, the hard and soft tissues around the dental implant are inundated with an influx of periodontal bacteria. These specific oral bacteria act as catalysts, accelerating bone deterioration and gum disease.
So, if you have a dental implant, and develop further progressive periodontal disease, it’s possible you’ll also experience a significant reduction in your gum line. This could then result in the exposure of the dental implant.
Because of the irreversible damage this infectious disease poses, it may be necessary for the dental implant to be immediately replaced so a healing process can take place.
Keep in mind, while these are things that can happen, as with any other procedures you might have, the risks of these happening and the implants needing replaced are very low. You can feel good about making the decision to get dental implants. In the long run, they are the best and safest choice available.
