ABSTRACT
Patient expectations for rehabilitations of a high esthetic standard as well as the demand for fast but efficient care have provided new work perspectives in dentistry. Dentists also have to choose between conventional and digital workflows. The aim of the present randomized restorative trial was to compare diagnostic waxing (DW) performed conventionally with its digital counterpart and to assess the two approaches from the point of view of both patient and dentist. Twenty patients with esthetic complaints were selected to undergo molding processes to obtain conventional study models on the one hand, and intraoral scanning to obtain virtual models on the other. Both the 2D planning and 3D virtual models were sent to the laboratory for the performance of DW. The restorative trial was evaluated by one evaluator dentist, while patient opinion was determined through customized questionnaires. The results show that although 80% of patients rated the digital method to be more convenient in terms of execution time and comfort and indicated that scanning was the most reliable way to obtain an impression, 65% chose the conventional DW for their esthetic restoration after the mock-up tests were performed and analyzed. The evaluating dentist preferred the conventional DW technique in 50% of cases assessed. The conclusion is that although digital technology has its advantages, the final esthetic result does not always meet the expectations and demands of patients and dentists.

Este estudo foi descritivo e teve como objetivo avaliar os enceramentos diagnóstico convencional e o digital, baseados no mesmo Planejamento Digital do Sorriso em 2D, realizado através de um protocolo fotográfico. Foram selecionados 20 pacientes, que foram moldados com alginato para obtenção dos modelos de estudo convencional e foram também escaneados para a obtenção do modelo virtual utilizado para o enceramento digital. O planejamento 2D foi então enviado ao laboratório de prótese juntamente com os modelos em gesso e os modelos virtuais, realizando então os enceramentos diagnósticos. A prova destes enceramentos foi realizada por meio de um ensaio restaurador seguindo uma ordem aleatorizada. A avaliação do ensaio restaurador foi feita sob a preferência de um dentista avaliador experiente e especialista em prótese dentária e do paciente através de questionário. Foi avaliada também, a preferência do paciente em relação às técnicas de impressão: analógica e digital. As respostas foram tabuladas e submetidas a teste estatístico. Os pacientes mostraram preferência pelo enceramento diagnóstico convencional em relação ao digital em 65% dos casos. Os pacientes mostraram preferência pelo método de impressão digital em relação ao convencional em 80% dos casos. O dentista avaliador mostrou preferência pelo enceramento convencional em 50% dos casos e pelo digital em 50% dos casos(AU)
This study was descriptive and aimed to evaluate the conventional and digital diagnostic waxing, based on the same 2D Digital Smile Planning, performed through a photographic protocol. Twenty patients were selected, who were molded with alginate to obtain the conventional study models and were also scanned to obtain the virtual model used for digital waxing. The 2D planning was then sent to the prosthesis laboratory together with the plaster models and the virtual models, performing the diagnostic waxing. The testing of these waxing was performed by a restorative assay following a randomized order. The evaluation of the restorative trial was made under the preference of an evaluating dentist and the patient through a questionnaire. It was also evaluated the patient's preference over printing techniques: conventional and digital. The answers were tabulated and subjected to statistical test. The patients showed preference for the conventional waxing over the digital one in 65% of the cases. Patients showed a preference for the fingerprint method over the analog in 80% of the cases. The evaluating dentist showed a preference for analogous waxing in 50% of cases and digital for waxing in 50% of cases(AU)
