Fractured Dental Implant? (photo)

Based on the x-ray, the implant does appear to be fractured.  This was most likely not done by trying to remove  a broken screw.  you have to realize that you are using four implants to replace 12 or more teeth.  Sometimes the force is just to great on the implants.  Do not get me wrong, all-on-four does work and is very successful.  Your implant do seem narrow and may have just taken to much force and thus fractured.  Most likely best to see a periodontist or oral surgeon that works with a good prosthodontist.

Your dentist can still remove and replace the implant. You will probably need a new set of teeth since this is precision fit. (Implantologists do not exist, a specialist is to be referred to as the specialty field they studied. There is no implant specialist). According to your story you felt the debris after attempted removal. This attempt was done engaging it internally. The next attempt should be with a screwed in abutment and attempted externally with a wrench. Final attempt is trephining the implant out. Grafting or replacement with a wider implant implant may follow. Most implants of today are made of the same titanium alloy. Even if the manufacturer does not replace it free of charge (i choose those that do), your doctor should take care of it for you. The cause should be aware of, that way it won't repeat. Dr. Dorfman pointed a couple out. Your dentist should investigate. Its unfortunate you will have some down time, but you will be fine afterwards.

This is certainly unusual. But the only option is to remove the fractured implant as conservatively as possible. We use a special tool for removal of failed implants that does not require 'bone cutting'. This way the bone can be preserved for replacement of a new implant. Once the site heals in 2-3 months, a new implant can be placed.
