When Dental Implants Fail

Posted in Dental Implants

Dental implants are a successful way to provide predictable smile restoration and rehabilitation to the mouth. Unfortunately, there are times when dental implants can also fail, creating the need for removal or re-treatment. Here are some common reasons that implants fail after they have been placed:

Inadequate bone support

Bone is necessary to hold the implant into place. If there is not enough bone, a graft may be needed to help bone be rebuilt. Or, a dentist may use computer guided implant placement to arrange the position of the implant so that it maximizes what bone is present. Placing an implant in very shallow bone may result in mobility or loss of the implant. 

Infection around the implant

Abscesses, cysts, and infections can develop around newly placed implants. This may be due to the implant being placed without proper sterilization techniques, into an infected area, or in a way that damages facial nerves. Typically, the infection will be visible on an x-ray. Milder infections around the implant that are similar to gingivitis may be treated with an antibiotic or prescription mouthrinse. 

Rupture of the nasal sinuses

Implant roots extend just as far into the bone as a normal tooth root. Sometimes when teeth have been missing, the lining of the nasal sinuses will drop into the area. It is necessary to perform a sinus lift before placing an implant here, because there is a potential for the implant to puncture the sinus lining.

It’s important to choose an implant provider that has the experience and skill needed to provide long-term, successful implant therapy. Ask about your dentist’s training and experience with implants.
