A dental model is attachable to and easily removable from a dental articulator arm by cooperating magnetic components, one fast with the arm and the other connected to the dental model. The cooperating attaching components are of wear-resistant material and are formed with interfitting aligning means. The arrangement is such that a dental model mounted on the articulator arm in a predetermined position may be detached by simply pulling the model away from the arm with sufficient force to overcome the magnetic attraction. Thereafter, the model may be replaced on the arm and positioned in the same predetermined position by the cooperation of the interfitting aligning means, and held magnetically in that position.
