A dental implant, in which a crown made of zirconia is coupled and joined to an abutment by first and second joining holes that are concentrically formed in the crown and the abutment and a joining pin that is inserted into the first and second joining holes. Thus, the crown can be fixed to the abutment through simple structure and method which prevents a separation of the crown from the abutment after fixing. The crown can be easily removed by removing the joining pin without damage to the crown. A housing is mounted inside the first joining hole of the crown and the housing is screw-coupled with the joining pin or the joining pin is fixed by a magnetic force to thereby prevent a separation of the joining pin. |
