Single Crowns: Digital versus Conventional Workflow. Systematic Review and Meta-Analysis.
Objectives: The aim of this systematic review and meta-analysis was to evaluate the manufacturing of fixed dental prosthesis (single crowns) about digital workflow compared to conventional workflow techniques in terms of accuracy, time effectiveness and patient satisfaction.
Methods: The search was performed in the Pubmed / MEDLINE, Embase and The Cochrane Library databases with articles published until January 2020. This review followed the PRISMA criteria and is registered in the PROSPERO platform. The PICO question was: "Does the use of digital workflow technique compared to conventional for manufacturing fixed dental prostheses (single crowns) improve accuracy, time effectiveness and patient satisfaction?"
Results: Thirteen studies were selected for qualitative analysis and 06 studies for quantitative analysis. All included studies are Randomized Controlled Trials (RCT). The included studies present a total of 259 patients, with a mean age of 49.35 years. Following the design of each study, a total of 465 crowns were made, distributed in two groups (conventional workflow or digital workflow). Regarding the accuracy of the crowns, the meta-analysis showed a significant difference between the groups for the digital workflow group (P= 0.003; MD: -23.82, 95% CI: -43.05 to -4.59), presenting higher accuracy. For clinical time analysis at each impression, an average of 484.4 seconds was verified for the digital workflow and 731.75 seconds for the conventional workflow. Patient satisfaction was assessed using the Visual Analog Scale (VAS), and was influenced by the type of scanner and the clinician's experience.
Conclusions: Within the limitations of this systematic review and meta-analysis, it can be concluded that the digital workflow technique presents greater precision in the acuraccy of the single crowns, as well as shorter clinical time to perform the technique. Patient satisfaction will be influenced by the type of scanner system used and the clinician's experience.
