Objectives The aim of this RCT was to analyze Patient Reported Outcome Measures (PROMs) of implant crowns processed in complete digital workflows (test) and combined analog‐digital workflows (control) with a three‐year follow‐up. This is a second reporting from the same trial with sample size calculation based on time efficiency. Materials and Methods Twenty participants were selected for single‐tooth replacement with screw‐retained crowns in posterior sites (Straumann TL Implant System). Ten patients each were treated with test or control workflows and evaluated after 1 week of prosthetic delivery (baseline) and 3 years. The subjective opinion of the patient was assessed using visual analog scales (VAS) for PROMs; the Functional Implant Prosthodontic Score (FIPS) for the objective evaluation of the dentist. Wilcoxon signed‐rank tests and Mann–Whitney U ‐tests were used for comparisons between test and control with a level of significance set at α = 0.05. Results In test and control, implant crowns showed 100% survival without technical and/or biological complications. Mean PROMs varied between 81.6 and 90.3 with no difference between test and control, or between baseline and after 3 years for intra‐patient comparison. Linear regression analysis exhibited a significant correlation between FIPS and PROMs related to overall treatment satisfaction (VAS‐1: coefficient 0.45; p = 0.0472). Conclusion Subjective patient's perception (PROMs) of posterior implant crowns processed in complete digital and combined analog‐digital workflows revealed comparable high levels of satisfaction on the overall treatment outcome including function, esthetics, and cleanability after 3 years. The objective evaluation of the dentist (FIPS) seems to reflect the perception of the patients.
