What is the treatment for metallosis?
Bone loss and tissue necrosis develop if metallosis is untreated. Surgery is the only effective treatment. If there is adequate bone remaining, the acetabular component can be repositioned, keeping the metal- on-metal resurfacing prosthesis. Most revision procedures are successful.

What are the symptoms of metallosis in dental implants?
Metallosis Symptoms. One of the most common is tissue or bone death (necrosis). With tissue or bone necrosis, the tissue around the implant turns gray or black from being exposed to the metal debris. This creates pain and instability, which can lead to spontaneous dislocation, bone loss and fracture. On occasion,…
