Novel functionalized Ti6Al4V scaffold for preventing infection and promoting rapid osseointegration

Materials & Design, 2023
Total hip arthroplasty (THA) is the most common and radical treatment for end-stage hip disease. Prosthesis loosening and periprosthetic infection are the most serious complications after THA, which may lead to prosthetic dysfunction.

Intraosseous sarcoidosis imitating peri‐implantitis: A case study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Sarcoidosis is a multisystem granulomatous disorder of unknown cause, typically affecting the lungs and lymph nodes, but it can also involve the eyes, skin, heart, bones, and other organs. The exact cause is unclear, but genetic factors and environmental triggers like infections, chemicals, or dust may play a role.
