Background   Temporomandibular joint (TMJ) arthritis is a degenerative pathology that may cause pain and dysfunction. Nonsurgical therapy is the traditional treatment of TMJ diseases but if ineffective, TMJ surgery can be performed and may include arthroplasty with interposition of autograft. The encouraging results reported with the use of human amniotic membrane (HAM) in different surgical fields have highlighted its potential, but approaches providing the positioning of HAM within the intra-articular space of arthritic TMJs have never been investigated.Case Presentation   A 48-year-old woman was presented with limited mouth opening and pain with palpation at the left joint. A severe TMJ degeneration was diagnosed, and a surgical treatment was necessary. In the present case report, the authors describe the application of a cryopreserved HAM patch within the joint space as a disc-replacing film during major surgeries for discectomy and arthroplasty. Three months after the intervention, the patient reported an overall improvement in chewing efficiency as well as the absence of pain.Conclusions   According to the regenerative effects of HAM, the design of trials on the topic should be encouraged for its possible inclusion within the field of TMJ disease practice.
