Model holding means and articulator for use with dental models and apparatus for adjustment of the articulator

摘要

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.
