Oral health impact on the quality of life (OHRQoL) of patients through the replacement of conventional complete dentures (CCD) to implant suported dentures (ISD) is still not completely clear due to the great methodological heterogeneity. The objective of this nonrandomized controlled clinical trial was to compare OHRQoL and masticatory performance (PM) in rehabilitated patients with CCD and ISD under lower immediate loading. The sample consisted of 40 individuals, mean age of 59.08 years (± 7.04), predominantly female (n = 36), were divided into two groups: CCD and ISD. All patients were rehabilitated with CCD initially, 23 remained with their CCD, and 17 patients after 3 months of CCD use had their dentures converted into ISD under immediate loading, supported by 3 or 4 implants. The OHRQoL was measured by OHIPEdent questionnaire (Brazilian version) and the PM, using the sieve method with the calculated X50. Data were collected before (T0), and after 3 months of installation of CCD and ISD (T1). Student's t-test for paired samples was applied to evaluate the same group before and after the clinical intervention, in the comparison between the groups the t test was applied for independent groups and the "d" of Cohen calculated for both groups comparisons. Spearman's correlation test was used to evaluate the correlation between the variables. Comparing the CCD group at T0 and T1, there was no positive impact on the OHRQoL and no significant X50 reduction, which indicates that there was no improvement in the PM. For ISD, there was an improvement in the OHRQoL (p < 0.001) with a large size effect (Cohen'd = 2,49) and a significant improvement in the PM with a large size effect (Cohen'd= 2,47). Comparison in time T1 for both groups, ISD presented lower OHRQoL and lower value of X50, which indicates a higher positive impact on the quality of life and better PM when compared to CCD (p < 0.001). Correlation between PM and OHIP-Edent was found only positively for CCD at time T0, in the "psychological discomfort" domain, indicating that as the PM worsens, the psychological discomfort increases. It is concluded that the conversion of complete dentures into implanted suported denture has a positive impact on the quality of life and on masticatory performance.
