Abstract
A mould for casting a base for a dental model when reconstructing teeth for dentures or parts thereof and including a base plate along the edge of which a mould cavity is placed, the mould cavity including a bottom with fixating structures for the dental model or parts thereof, and walls provided with ribs extending from the bottom, the mould cavity having the shape of at least a part of a jaw. With a view to creating a stable mould, in which the model cast on the base may be remounted and positioned without rocking, the mould is designed in such a way that the fixation structures are at least substantially cylindrical pins which can be inserted in corresponding holes in the bottom of the mould cavity and which each include a portion suited for being cast in the base of the dental model.
