There are many ways to fix a removable prosthesis onto implants, and the method depends on the type of prosthesis and the number of implants that are to be employed. A widely used method is the ball-attachment, in which male spheres of approximately 2 mm diameter are screwed onto the implants and female rings or sockets are placed in the prosthesis, retaining the prosthesis by friction. The magnet method is also used, and different retention strength magnets are commercially available. Bars are structures that are screwed to the implants and are connected together, allowing the fixation points for the prosthesis to be distanced in order to achieve a better retention (42)(54).
