IMTEC Hybrid Implant is Loose: What is the Cause?

DR. A. Firstly, I am not familiar with the product you used for your "bone grafting" technique and ridge preservation. You certainly waited a sufficient amount of time before implant placement, and since 3 of the 4 implants are stable ( assuming they gave you at least a 30-35Ncm Torque reading upon placement)then I would have to suggest the quality of bone at the "failed site" is the culprit..and suggest moving the next implant to another area ...if that fits into your prosthetic scheme (which was not mentioned by you..fixed or removeable case?). Hope this is helpful and good luck. The 3m EPSE 2.9mm Hybrid is an excellent implant and, as with all implants, mini- and standard, good protocol practices need to be followed..but, sometimes we get "fooled" by the quality of bone at a specific surgical site.

implants are not 100% perfect. Sometimes S(tuff) happens. Mother nature doesn't always cooperate. Don't beat yourself up!

mother nature ! if you (Dr.J ) hurt by the mother nature but in the hospital can you forgive your doctor ? dear Dr.A you didn't mentioned the loosing of the implant when happened ? before loading or after loading ? to distinguish the reason of the implant's failure it is very important to seprate the surgical causes from the prosthetic problem. please write the complete data. be lucky !

Dear Dr.A, i,ve been apointed as a lecturer by imtec co.in all the world,so i ,ve seen many such failures in past(not for hybrid of course)but the only thing which should happened is a personal mistake in time of placing the fixture,have you used the 1.7 drill?placement torque not exceeding 35 N?or any such reasons? any way you have been successfull on 3 other fixtures,so do not hesitate,change the failed one (i,m sure the company will pay for it)and place the next one in a new zone.and always remember that even in best cases and by considering all aspects of a clean and protocolized urgery there is a 2=3% chance of failure.luck for you

As the hybrid implants are single piece, it has been my experience that it is often occlusal forces on the fixed abutment during early healing, that cause them to come loose. More than any other implant I am convinced that they must be treated carefully to ensure that these interferences are not present at insertion.

Dr. Dunn One of the main advantages of this system is that you are supposed to be able to load them immediately when you have multiple implants and cross-arch stabilization as with a full arch overdenture. How would uo manage these one-piece implants if you could not load them immediately? SimpleDoc

Dr A...I am not familar with VitalOs. But it seems it is more a cement of Calcium Phosphate to use during implant placement not to augment the socket after extractions. However it might be possible to do so. I would suggest contacting the manufacturer of the VitalOs to see what their thoughts are. But to answer your question I think the Mini Hybrid came loose due to the patient finding a way to function on the one piece before integration was complete. My recommendation is to remove place an allograft and replace the mini to a new location if possible. Best regards.

Dear dr.A Two opthions: 1) before loading; the specified implant had been under trauma by the upposing tooth. 2) after loading; extra force on the specified implant causing loss of implant hopping it helps.

Dr. there are 2 main reasons for an implant to fail, 1. micromotion(beating the 150microns force) or 2.infection, the micromotion is related to your primary stability(torque) vs the biomechanical factors affecting the implant(occlusion,tongue,ect). About the bone graft even if you waited 4 month(remember this depends also on location and bone density) if the material you use does not resorb in that time or is osteocinductive and osteoconductive you wont have the appropriate density for the implant to osseointegrate in that receptor site. Also make sure you don`t incorporate CT or ET into the osteotomy I hope this helps.
