RESUMO

Complete denture fabrication involves a series of complex technical procedures. Nevertheless, simplified methods may be as effective as conventional ones albeit the lower use of time and resources. The aim of this study is to quantify the costs of complete denture fabrication by means of a simplified method compared with a conventional protocol. A sample of edentulous patients needing conventional maxillary and mandibular complete dentures was randomly divided into: group S, which received dentures fabricated by means of a simplified method, and group C, which received conventionally fabricated dentures. We calculated direct and indirect costs for each participant including unscheduled procedures. This study assessed 19 and 20 participants allocated in groups S and C, respectively, and comparisons between groups were conducted by means of the Mann-Whitney and Students t test (α=0,05). Complete denture fabrication demanded median time periods of 173,2 and 284,5 min from the operator for groups S and C respectively, and 46.6 and 61.7 min from the dental assistant (significant differences, P<0.05). There was no difference between groups regarding postinsertion adjustments. Group S also showed lower values than C during the fabrication stage, but not during adjustments, for costs with materials and time spent by patients. In summary, the simplified method reduced direct treatment costs in 34.9%. It can be concluded that the simplified method is less costly for patients and health system when compared with a conventional protocol for the rehabilitation of edentulous patients.
