Abstract

An oral implant for supporting an artificial tooth structure includes an implant portion which is buried in the bone of the patient along the occlusal plane. A neck portion extends from the side of the implant portion remote from the groove and receives a post portion on which the artificial tooth structure is cemented. Means are provided on the neck portion so as to cause it to become wedged within a cavity of the overlying post portion, thereby releasably locking the post to the neck portion. As a result of this arrangement, a bridge structure can be removed from an implant without having to destroy the bridge.
