ABSTRACT:
Mechanical joining of a two-phase tooth implant, consisting of two components which are joined by means of a conical pin projecting into a conical sleeve, the cone pairing being realized within the self-locking region and the cone pin being penetrated by a centrally aligned, tension screw reduced diameter which tensions the pair of cones against each other. The design permits the two implant components in a two-phase tooth implant to be steplessly positioned in the circumferential direction and to be joined in an anti-rotation, gap-free joint. The required degree of miniaturization, with a sufficient component strength, is achieved through the use of a cone combination in the self-locking region and through the use of a tension screw in the region of the cone joint. By these means, the mechanical, aesthetic and hygienic requirements for a two-phase tooth implant are better fulfilled than in the case of the known designs.
