A dental pin and bushing assembly for coupling of a removable die portion of a tooth from a working cast. The pin includes an axially extending head portion which can be secured within the die. The coaxial body portion depends from the die portion and includes an offset section for oriented insertion of the pin in the bushing. The bushing is secured in the working cast and includes an elongated sleeve with a mating chamber for receiving the pin. The bushing matingly receives the body portion of the pin so that the removable die can be inserted in only a single oriented direction into the bushing. |
