Abstract
An implant portion of an oral implant arrangement for supporting an artificial tooth structure has an elongated body having a first and a second ends. The first end is adapted to receive at least a portion of the artificial tooth structure. The second end is adapted for insertion into a crypt in a bone located to support the artificial tooth in the vicinity of the occlusal plane of a patient. At least one longitudinal column projecting outwardly from the outside surface of the elongated body and extending at least part way toward the second end of the body is provided. A cutting arrangement is defined at the end of the longitudinal column toward the second end of the body. During insertion of said elongated body into the crypt in the bone the longitudinal column closely engages slots formed within the walls of the bone crypt by the cutting arrangement so as to create at least one antirotational pillar which resist accidental spinning of the implant portion in the crypt.
