ABSTRACT:
The method of making a dental device or the like which involves starting with a pattern of the device to be made, closely surrounding that pattern with a settable material to form a unit with the pattern, separating the unit and removing the pattern therefrom, filling the thus produced space with settable material of the type desired for the ultimate device, setting that material and removing the set material constituting the device to be made, and in particular utilizing a retention device to enclose the settable materials and other contents. The process is particularly useful when the device is to be made of a light-sensitive material, in which case the retention device and the first-used settable material are light-transmissive and the retention device preferably focuses light on the material to be set.
