This study aimed to assess the ability of inexperienced and experienced BDS students and teachers of removable partial denture (RPD) design, to prescribe/design RPDs for an identical partial denture case. Second and fourth/fifth year BDS students and experienced teachers of RPD design were selected to provide a treatment plan for a patient requiring RPDs using identical models. The designs produced were compared against a design produced by the authors before the study began. Not one design for the 100 participants matched the author's design. Under 30% of second year students surveyed the models before designing. Only a small percentage of the participants indicated the path of insertion and removal they had chosen and less than half the student groups and only 60% of the staff group provided clear, correct instructions to the technician. Large disagreements existed between the individuals within groups and between individual groups regarding the selection of component parts. There were wide differences in opinion among the undergraduate student groups as to which are the best design options for particular cases. Teachers of RPD design were found to be far from confident and have no consensus of opinion when designing RPDs.
