| Zusammenfassung: | One embodiment of the present invention provides an abutment assembly comprising: an abutment coupled to a fixture implanted in the alveolar bone; an artificial tooth-shaped crown seated on an upper surface of the abutment, and formed with a through-hole in a center; a washer inserted above the through-hole and in contact with an inner surface of the crown; and a screw coupled to the abutment through the washer, wherein when inserting the screw, a force is applied radially outward in the washer so that the washer and the crown are elastically coupled. Therefore, the present invention is capable of enabling the crown to be securely coupled to the abutment without a dental cement.
