After discectomy, interpositional implants (IPIs) are believed to provide temporomandibular joint stability and protect against degenerative joint space remodeling. Alloplastic IPIs gained popularity in the late 1970s because the practice showed early success without donor site morbidity. Unfortunately, these implants were subject to substantial fragmentation resulting in an exuberant foreign body giant cell response that progressively eroded adjacent structures. Most of these alloplastic implants were removed in the years following their recall by the US Food and Drug Administration in 1991, however some remained in circulation. This report describes a case of a failed Proplast/Teflon IPI 27 years after its placement. This case highlights the considerations for managing a patient with a Proplast/Teflon IPI and serves to remind providers that, although increasingly rare, these implants are still present and subject to delayed failure.
