A systematic review of studies comparing conventional complete denture and implant retained overdenture.

Purpose: Several studies reported better outcomes when restoring edentulous mandible with unsplinted IODs compared to CCDs; however, it is not clear if these outcomes remain when the full literature is considered. The aim of this systematic review is to compare conventional complete dentures (CCDs) to unsplinted implant-retained overdentures (IODs) with regard to efficacy, satisfaction and quality of life.

Study Selection: The main question addressed was: How do CCDs compare to unsplinted IODs with regard to efficacy, satisfaction and quality of life? Three databases were electronically searched to identify articles comparing CCD to unsplinted IOD.
