Abstract: A series of die spacers of differing shades are used to match or replicate an assortment of tooth stump or dentin tooth shades. Such die spacers correspond to shades of various manufacturers. This allows the dentist to approximate the proper shade of the tooth preparation in his prescription of a translucent restoration which is communicated to the technician. The technician then applies onto the die of the tooth preparation a die spacer closely matching the chosen tooth stump shade, allowing the technician to wax-up over the die with the selected die spacer. The die spacer retains the traditional function of creating the necessary space under the wax pattern or wax-up. After removal of the wax-up from the die, it is processed, following the manufacturer's procedures, to make a non-opacious substructure of, for example, a translucent ceramic restoration.

Abstract: A gauge for measuring in situ the diameter of a borehole in salt or other ft creeping rock types is provided so that changes in borehole structure can be detected. The gauge comprises a cylindrical body insertable lengthwise into a borehole and having an internal channel wherein sensors can be displaced outwardly when air is directed into the gauge, two air displacement sensors located in the channel having slotted keyways at their inner ends which form an orifice proportional to the distance between the sensors, a pneumatic device capable of providing a stream of air into the gauge body, and a flow meter for measuring air flow through the gauge body. The borehole diameter is determined by directing a stream of air into the gauge body and measuring the air flow which will be proportional to the distance between the sensors when displaced outwardly against the borehole walls. The gauge is advantageous in that it does not itself create artificial stresses or deformations in the borehole walls.
