With a quantitative approach, 280 working models for the preparation of removable partial dentures were included in the study.

The results found 73 (91.3 %) did not make a system of design (instructions from the dental professional about the design that the RPD should have) delegating the design choice to the dental laboratory technician and a smaller percentage followed the instructions for the elaboration of the RPD 7 (8.8 %), from which 51 (63.8 %) were superior dental arches and a smaller percentage of them were the inferior dental arches 29 (36.3 %). The design quality of the removable partial denture base in working models, whose design was acceptable to 46 (67.5 %). It is concluded that the design quality of the removable partial dentures in a high percentage is designed incorrectly, the components used do not meet ideal requirements. 22.86 % of the dentists send the working models with system of design for the fabrication of the removable partial dentures.
