The ERA implant-supported overdenture

Extracoronal Resilient Attachment (ERA) implant-supported overdentures, Class I, Division 1 or Division 3 prostheses, provide an exceptionally stable and retentive prosthetic design for edentulous patients with osseointegrated implants. The ERA System uses either an individual female implant abutment or plastic female patterns that can be incorporated into a bar. The male portion of the attachment is a nylon piece of varying retentive quality. The attachment is resilient, stable, and can be easily serviced.
