Influence of Age and Time Since Edentulism on Masticatory Function and Quality of Life in Implant-Retained Mandibular Overdenture Wearers: 1-year Results from a Paired Clinical Study

Abstract

Neither the age nor the time since edentulism influenced the masticatory function of IMO-wearing patients. However, IMO significantly improved the masticatory function in totally edentulous patients, and this is more evident for younger patients (≤ 65 years) with a shorter time since mandibular edentulism (< 25 years). The OHRQoL is only influenced by age and time since edentulism in complete denture wearers; IMO treatment eliminates these differences.
