The article describes a patient with a history of facial trauma, with bilateral ankylosis of the TMJs, inability to open his mouth, and poor dental condition. Due to a long period of immobilization of approximately 40 years, the initial treatment plan was to remove the ankylosis bilaterally and install customized PMMA (polymethylmethacrylate) spacers. The patient gained mouth opening and improved chewing quality with one year of customized spacer use prior to definitive alloplastic replacement with stock-type TMJ prostheses.
