ABSTRACT:
A prefabricated abutment of precise size, shape and dimensions is fixed in a patient's jawbone, as the supragingival part of an endodontic post, or an implant, for example. The post is used in combination with a prefabricated sleeve-like coping which is telescopically mated to the post with a high degree of dimensional precision. A finished crown is fixed rigidly to such a coping, or replicates its internal dimensions, so as to use the post as its support.
