ABSTRACT:
A dental disc and sleeve assembly for removably coupling die portions of teeth from a dental model onto a cast base. The disc is inserted into a semi-circular cut formed in the underside of the die portions so that the disc is secured in the die and partially protrudes therefrom. A sleeve secured in the cast base has a head portion having a chamber matingly receiving the protruding portion of the disc and a tail portion. Two knobs provided on the opposite sides of the disc are snapped into two grooves formed at two opposite sides of the chamber. The grooves can release the knobs and the disc can be removed from the sleeve when slight pressure is applied to the tail portion of the sleeve to remove the die portion from the cast base.
