Details and patient eligibility

About

Purpose: To assess the clinical and radiographic outcomes of computer-aided designed and manufactured (CAD-CAM) zirconia bars supporting mandibular implant-retained overdentures (IODs) after a 3-year follow-up.

Methods: A prospective observational single-center study involving 30 edentulous patients rehabilitated with two mandibular implants and a mandibular implant overdenture supported by a computer-aided design - computer-assisted manufacturing zirconia bar with distal extensions was performed assessing clinical and radiographic parameters.
