1. An apparatus for associating a plurality of landmarks with a patient tissue, the patient tissue including a primary patient tissue area forming an abutment surface for an implant, and an anatomically differentiated bordering secondary patient tissue area excluded from the abutment surface, the apparatus being at least partially customized responsive to preoperative imaging of the patient tissue, the apparatus comprising:

  • means for mating with the primary patient tissue area in a preselected relative orientation;

    means for fixing a first landmark to the primary patient tissue area in at least one of a predetermined marking location and a predetermined marking trajectory, into the abutment surface, the first landmark directly related to a planned position of an implant onto the primary patient tissue area;

    means for fixing a second landmark to the secondary patient tissue area in at least one of a predetermined marking location and a predetermined marking trajectory excluded from the abutment surface; and

    a pin used as the second landmark, the pin having an elongated portion being a guidewire configured to project out of the secondary patient tissue area to be used as guide for the predetermined marking trajectory, the predetermined marking trajectory being that of a tool altering the abutment surface based on the planned position of the implant after removal of the apparatus.
