Question 1

What is dental implant failure?

Accepted Answer

Dental implant failure occurs when an implant does not properly fuse with the jawbone (early failure) or loses its integration after a period of successful function (late failure). It means the implant is no longer stable enough to support a crown or bridge.

Question 2

What are the causes of early implant failure?

Accepted Answer

Early failure, which happens within the first few months, can be caused by poor bone quality, infection at the surgical site, smoking, uncontrolled systemic diseases like diabetes, or surgical trauma.

Question 3

What are the causes of late implant failure?

Accepted Answer

Late failure occurs after the implant has healed and can be caused by peri-implantitis (the most common cause), excessive biting forces (bruxism), poor long-term oral hygiene, or trauma to the implant area.

Question 4

What is peri-implantitis?

Accepted Answer

Peri-implantitis is an inflammatory disease, similar to gum disease, that affects the tissues and bone around an implant. It leads to bone loss and can cause the implant to become loose.

Question 5

What are the signs and symptoms of a failing implant?

Accepted Answer

Signs include pain or discomfort around the implant, swelling or redness of the gums, pus or discharge, loosening of the implant or the crown, difficulty chewing, or receding gums around the implant.

Question 6

How can I prevent dental implant failure?

Accepted Answer

Prevention is key. This includes choosing an experienced surgeon, maintaining excellent oral hygiene, attending regular dental check-ups, quitting smoking, and managing any systemic health conditions.

Question 7

Does smoking increase the risk of implant failure?

Accepted Answer

Yes, smoking is a major risk factor. It impairs blood flow and healing, significantly increasing the chances of both early and late implant failure.

Question 8

What is the treatment for a failed dental implant?

Accepted Answer

Treatment depends on the cause. It can range from non-surgical cleaning for early peri-implantitis to surgical debridement, bone grafting, or complete removal of the failed implant.

Question 9

Can a failed implant be replaced?

Accepted Answer

Often, yes. After the failed implant is removed, the site is usually cleaned and bone grafted. Once the area has healed completely, a new implant can often be placed successfully.

Question 10

What is the success rate of dental implants?

Accepted Answer

Dental implants have a very high success rate, typically over 95%. Failure is rare but can occur due to the various factors mentioned.
