Patient- and Clinician-Reported Outcomes and Outcome Measures Evaluating Timing of Implant Loading in the Edentulous Maxilla: A Systematic Review of Prospective Studies.

PROs were predominantly assessed using VAS to evaluate patient satisfaction, pain, function, and esthetics, followed by the OHIP Questionnaire for quality-of-life assessment in immediate versus early/delayed loading protocols. ClinROs showed no standardized approach, creating significant heterogeneity in the reported outcomes. Standardization of assessment methods and reporting of PROMs/CROMs is needed to optimize analyzing patient-centered outcomes.
