摘要
The present invention relates to an implant in which the coupling force of a crown and an implant abutment having a separate coupling structure is strengthened in order to prevent separation of a crown and an implant abutment after a procedure has been completed. The conventional implant abutment and the crown are simply adhesively bonded to each other and there is a problem that both can be separated from each other during repeated use for a long time. The implant abutment is seated and coupled to the upper side, and in the insertion hole formed on the upper side of the implant fixture, an abutment fixing screw passing through the implant abutment from the upper side is screwed to the implant fixture and the implant abutment, and the crown is on the upper side of the implant abutment. In the implant coupled to surround the outside of the implant abutment, a single or a plurality of first pattern grooves having a predetermined pattern are formed on the outer surface of the implant abutment having a cylindrical structure, and on the inner surface of the through hole formed in the central portion of the crown A single or a plurality of second pattern grooves having a constant pattern are formed, and the first pattern groove and the second pattern groove are formed at different heights by a manual cutting machine or a CNC milling cutting process by a computer in the processing stage of the implant abutment and the crown. It is formed to form a structure that is crossed or formed at the same height to form a structure facing each other, and the space formed by the first pattern groove and the second pattern groove is filled with an adhesive component including a resin or cement-type adhesive to form a titanium material. A screw type that separates the implant abutment fixed to the crown and the implant fixture installed in the alveolar bone by disassembling the screw connection of the abutment fixing screw when the implant abutment and the zirconia crown are fixed in advance in the working room, and when the implant is repaired after surgery ( We propose an implant in which the bonding strength of the crown and the implant abutment is strengthened, characterized in that it is composed of a screw type implant. The implant in which the bonding strength of the crown and the implant abutment is strengthened according to the present invention forms a first pattern groove on the outer surface of the implant abutment, and forms a second pattern groove on the inner surface of the through hole of the crown, the first pattern groove and the second pattern groove The space formed by the two-pattern groove is filled with an adhesive component including a resin or cement-type adhesive, thereby preventing separation of the implant abutment from the crown. In addition, the first pattern groove and the second pattern groove of various structures can be simply implemented by a manual cutting machine or a CNC milling process by a computer, so that a more effective coupling structure can be adopted according to the shape and size of the crown.
