ABSTRACT:
A ball retainer for spanning and connecting an anchor osteointegrated into the jaw of a person and a dental prosthesis intended to be connected to the anchor. The ball retainer is formed in two separate parts. The first part has a column atop which is mounted a ball for engaging the prosthesis. The column has excess or sacrificial material. The second part has a hexagonal or otherwise non-circular shank for being inserted into and engaging the anchor, atop which is located a platform having a flat top surface. When being utilized in a particular prosthetic installation, excess material of the column is planed or otherwise removed to adjust height of the prosthesis from the anchor. Simultaneously, the cut is oriented appropriately for accommodating misalignment between the anchor and the intended orientation of the prosthesis. Preferably, the column is similar in diameter and cross sectional configuration to the platform of the anchoring member, and both are greater in diameter than the shank.
