Implant retained overdentures are an established treatment modality. ERA abutments provide a resilient attachment with universal hinge movement. Available as one piece straight abutment-screwed into implant and as a two-piece angled abutment (angled attachment cemented into abutment base, and base screed into implant).
A prefabricated device intended to provide a permanent intermediate fixture level between a dental implant and the final prosthesis/restoration (e.g., bridge, single tooth, overdenture). It includes one or more structural component(s) [e.g., abutment, ball, bar, bar overlay, coping, ring], and may be made of various materials [e.g., titanium (Ti), plastic, gold alloy]. It includes devices glued to prostheses and/or devices that can be replaced during cleaning cycles. An abutment screw(s) may be included, however the suprastructure does not represent the screw(s) in isolation. It may also be referred to as an abutment assembly or mesostructure.
