Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.
