The link of customized zirconia abutment for droping out and node of zirconia coping

摘要

The present invention relates to a link for a custom zirconia abutment for preventing dropout and fracture of a zirconia cap, and more particularly, to a link for a zirconia abutment which is formed in a columnar shape and has an insert groove having a flat inner circumferential surface in a downward direction A fixture connecting portion of a titanium material having a lower end plugged in and fixed to an insertion groove of a fixture inserted and fixed to the alveolar bone and a titanium material integrally formed with the fixture connecting portion at an upper portion of the fixture connecting portion, And a cap connecting portion having an outer diameter of the other end formed to be smaller than the outer diameter of one end, the cap connecting portion being made of a titanium material having one end coupled to the upper surface of the supporting portion and integrally formed with the cap connecting portion, The other end of which is releasably engaged with the upper prosthesis One end of the cap doedoe combined in a way that is inserted to be fitted in the interior of the zirconia material of the cap made such that abuts on the upper surface of the support, characterized in that the coupling to be positioned on the other end of the other end cap of the cap connector. The length of the link is set to be as long as the length of the zirconia cap regardless of the size of the zirconia abutment to be performed according to the patient, so that there is no fear of dislocation of the zirconia cap at the link. In addition, according to the present invention, the portion of the link provided inside the zirconia cap is reduced in size toward the upper portion so that the thickness of the zirconia cap is maintained at a certain level, and there is no fear that the zirconia cap will be broken by external force.
