Thoughts on the reason for implant failure?

I do not see how the image you posted shows anything about the implants' stability. I also have concerns as to what your plans were restoratively for these fixtures? I do not think, even if both of them integrated, that they would provide adequate stabilization for an overdenture.

Do you have pre-op and surgery radiographs and photos?

Dr Milankov DDS Its looks like there is D1 what means: there we are a "short" with blood vessels, and that means there are a low regenerative capatibilities of the bone tissue. Solution: made some porous, 5-10 holes, small diameter, aground the implant place , first, and place implant in that area after 10-15 days.

When the extractions were done the surgeon may not have done a thorough debridement. Thus leaving remnant bacteria that may encapsulate themselves for survival and later then colonize the implant surface. The mandible appears very thin. Would it be possible to place implants in the anterior mandible and cantilever the posterior teeth. The failed implant has cost some supporting bone and this patient has a risk for fracture during function. It may be best to remove the failed implant, graft with primary closure and admonish the patient as to a fracture. The angulation is not a problem. Of course angled abutments are needed. There is a lack of a lot of information so any responses would be submitted with that caveat.If the failed implant is the more mesial implant then consider mini implants and a fixed restoration.

sir i feel it would be better if the prep op x rays are posted as it would help in proper analysis. but as per post op x ray i guess the angulation may not be feasible for fixed prosthesis .a transitional over denture would be a better choice among prosthetic option.or planning for another implant would be better.

"What do you think could be the reasons for this failure?" You say you achieved good implant stability. What does that mean? 45Ncm? Was the bone vascular? Did you have plenty of irrigation? Has the patient been wearing a partial over the site? "How can I manage this case now?" How long has it been integrating? Can you back it out and replace it?

Dear Dr , please provide more detail about the case, i.e healing time, temporary, final prosthetic, occlusion, dentition. OPG From this PA one can only guess what went on. My guess is that you have 2 implants placed at unfavourable angels, and there is some radioluscencies and bone resorption around them. I don't think you can even restore this with a fixed prosthesis due to too sharp of placement angels. I guess your best bet is to remove them, graft the defects and start over.

ABORT!

Help us to help you. If you want meaningful clinical advice on managing this case (or any case) you will need to provide enough meaningful information so others can get a good handle on the patient, the pre-tx situation, the tx-plan, the treatment, and the current situation. Don't force others to make guesses...it is way too easy to give advice that doesn't even apply to your case. IMHO it is not possible to give you any meaningful advice based on what you provided. (Myself, I can't even tell what the X-ray is showing, other than 2 implants in the field of view of what I presume is somewhere in someone's mandible.)

Agree- This X ray looks like a piece of a pig mandible that I learned how to use an implant drill with. More information if you want help.
