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.

Abstract: Articulator for dental modelling, such as restoration of individual teeth and the manufacture of bridges or the like, comprising an upper part and a lower part mutually connected by a hinge, which makes it possible to simulate a movement approximately corresponding to a chewing movement, between the upper part and the lower part as well as a device for adjusting the upper part in relation to the lower part to establish a correct mutual engagement between the models mounted on the two parts and a subsequent fixation thereof. The articulator, of which the adjustment can take place shortly after the models have hardened and are ready for further working up, has an upper and lower part, each comprising a mould having walls with a toothing, one of the parts comprising a stanchion made of thermoplastics, the stanchion carrying one part of the hinge, with the hinge being separable. An apparatus having a nozzle is also provided, for supplying a jet of hot air through the stanchion, which is preferably tube shaped.
