The 2018 ECG Research Award, sponsored by, was attributed to a study presented by Dr Túlio Nogueira from the Federal University of Goias in Brazil, entitled: “Single-implant mandibular overdenture and masticatory performance: A randomized clinical trial”.
The research team included Dr Túlio Nogueira, Prof. Caudio R. Leles, Dr Fernanda Maria Oliveira Aguia from the School of Dentistry, Federal University of Goias, Brazil and Prof. Martin Schimmel from the School of Dental Medicine, University of Bern, Switzerland.
The aim of this study was to compare the changes in masticatory performance in edentulous patients rehabilitated with conventional dentures (CD) or single-implant mandibular overdentures (OVD), measured by the mixing ability of a two-coloured chewing gum. Based on the findings, masticatory performance in complete denture patients improved significantly after 12 months, irrespective of the stabilization with a single implant. The greater improvement in mixing ability in the OVD group after 6 months suggested that this group may have a different pattern in post-insertion changes in masticatory performance compared to the CD group.
