Resumo


A technique is described for selecting the RPA clasp (rest, proximal plate, Aker’s clasp) and making a Kennedy class I removable partial denture in the mandibular arch using the computer-aided design and computer-aided manufacturin technology. A benchtop scanner (3Shape®, Copenhagen, Denmark) captures the plaster cast image, and software (Exocad DentalCAD®, Darmstadt, Germany) processes it. All the initial planning was carried out; however, because of the digital flow analysis to obtain the printed cast, the design of the metallic frame was changed due to the need to modify the retention clip on the abutment teeth. The other clinical steps for the installation of the removable partial denture were followed in the laboratory to obtain satisfactory aesthetic and functional results. With this technique using the digital medium, the optimization of the workflow in dental prosthetic rehabilitation, easier work planning involving the clinical team and the dental technician, and the return of the masticatory function and aesthetics to the patient were observed.
