Abstract: A modular implant assembly utilizes standardized components removeably attachable to a base module. The module is anchored to the bone tissue and provided with a matrix of apertures and a series of sockets for threadably receiving the interchangeable components including a support post for an artificial tooth structure, a threaded pin for stabilizing the module within the bone tissue and other stock parts. The apertures and sockets are randomly accessable by the components which are externally insertable through the bone tissue. The components are further divisible into constituent elements and can be constructed in various combinations for attachment to the module. In a variant embodiment the module defines a cylindrical surface. A transverse cross bar extending diametrically over the cylindrical opening includes an aperture for accepting a vertical support post. In addition, the apertures within the cylindrical side surface will accommodate an anchor pin for preventing dislodgement.
