[Device used for mounting retaining pins in split models for fixed dentures]

Fixed dentures carried out by current laboratory method require to create potentialities of accurate separation of the working part of the model from its base preserving reciprocal parallelism of abutment elements. Modern engineering has at its disposal two methods of parallel location of stabilizing pins in model by means of devices produced in west European countries. Instructive needs and shortage of the appliance of this type on our market have made us elaborate our own design. In the design optical and mechanical elements available in the country are used and it meet exactly the requirements particular about devices of this type.
