Coating on dental implants that cause body to reject?

Can there be a coating on dental implants that cause body to reject them?

I have had three successful dental implants in the past, all by the same oral surgeon. Last June, I had two implants placed in my mouth, still by the same surgeon, and both of them spontaneously erupted back out within six weeks of surgery. This January, the same surgeon re-implanted a new implant in one of the sites that rejected an implant last July. This implant, also, spontaneously erupted through the gum within a month.

Are there implants that have any kind of coating that would cause my body to reject them? I cannot understand why the first three implants were successful, and the last three have failed. I was wondering if you had heard of anyone who had had this happen, and, if so, was the person able to have successful implants after the spontaneous rejection.

    I am not aware of any coating that is currently placed on a titanium dental implant. There is some research studies going on in which they are coating the implants with a special protein that can help create bone. That is still experimental.

    It is possible for implants to fail for several reasons, though it is not common. Infection around the post, smoking, grinding or clenching teeth, and boneloss are a few. It is rare for the body to reject an implant, especially since you have successful implants already. I assume that because the other implants have done well for you that your body is not actually allergic to the titanium post.

    It sounds like the bone is not integrating properly around the post. If this were your 1st round with the implants in that location I would have recommended that you allow the site to heal and then possibly have a bone graft and allow that to heal so that you know you will be starting with an adequate amount of bone. However, since you have had 2 implants fail in the same location you may need to look at other options for replacing the missing teeth. Depending on your situation a partial or bridge may work best for you.
