A prosthetic implant attachment system for mounting a dental prosthesis on a root implant including a base member having a lower end sized to seat on the upper end of an implant cylinder and an upper end of outer diameter substantially equal to the average outer diameters of various teeth, a securing device for securing the base member on the root implant, and various straight, angled or variable angled prosthetic heads for securing to the prosthesis. The upper end of the base member and the lower end of the prosthetic head have interengageable and indexable locking formations for preventing rotation between the parts which can be engaged in any of a number of possible relatively rotated fixed, indexed positions. A releasable securing device secures the prosthetic head to the base member. The prosthesis can be mounted on the prosthetic head by cementation, screw fixation, or other techniques. A system for preventing rotation of the base member on an implant cylinder is set forth as is an improved analogue pin that is removable from the model. An implant system with an orthodontic bracket is also described.
