ABSTRACT:
A dental implant prosthesis for use with an oral implant of the type including an implant shaft implanted in a suitably prepared bore in the jawbone of a patient and an abutment connectable to the implant shaft for supporting an external artificial tooth structure, comprises an insert which is insertable in the abutment and a spring-loaded pin which is guided through aligned holes of the insert and abutment and slightly projects outwards from the abutment. The tooth structure is pushed over the abutment, while simultaneously retracting the projecting portion of the pin against the force of the spring to allow the tooth structure to be slid past the pin and eventually to sit upon the gingival area around the bore. The pin snaps back and engages a hole of the tooth structure to securely lock the latter in position.
