Ball attachment for overdenture?

Thanks a lot! I know this site and I will try. Anyway will be hard to remove this screw I think. But I think will be harder and heavier for the patient remove the fixture...

Depending on the implant system, of course, it is not that difficult to remove a fractured screw. The idea is to use the principle of the reverse drill/torque, as developed by Niznick in the 90's and as described by Dr. Stuart Froum: “Techniques to Remove a Failed Integrated Implant”, Compendium September 2011, Volume 32, No. 7, Pages 22-30. Froum's article refers to a failed implant, but the same reverse drill technique can be used for fractured screws, as well. There are several kits now on the market now that have special reverse threaded tools and guides to help remove a fractured or broken screw. As mentioned in a previous post, I recommend the Mr Curette (MCT) kit. It’s the same principle as the other kits, but the MCT removal kit is simpler to use and is 1/3 of the price, as you get 2 kits in one, i.e. instruments to remove fractured implants, as well as, failed implants. You can buy both the fixture removal and the fractured screw removal kits as one complete kit at DDSGadget.com.
