Incorporation of an ERA attachment for obturator framework design: a clinical report

Swinglock framework designs have been used to retain obturators for some time. One of the problems with Swinglock designs has been loss of retention due to wear of the metal latch assembly. This clinical report describes the incorporation of an ERA attachment as the latch assembly of a Swinglock framework for an obturator. The premise behind this design was that wear would be at the expense of the nylon retention male component, which is easily interchangeable, rather than the metal component of the assembly. The life of the latch assembly, framework, and prosthesis would thereby be prolonged.
