ABSTRACT:
In a dental model, a plurality of parallel non-tapered guide pins are slidably seated within cylindrical cavities in an apertured retainer. Extending sections of the guide pins are secured within removable cast teeth, whereby the guide pins and their mating cavities permit withdrawal and replacement of the removable cast teeth while maintaining the alignment of the removable cast teeth with respect to the dental model.
