These are issues we must confront head on. Medical treatments are a double-edged sword; while we harness one edge for healing, we must also investigate the injuries caused by the other edge.
Regarding the impact of metal implants on the human body, as early as 1973, Dr. Coleman reported in the "British Medical Journal" (BMJ) elevated blood and urine levels of cobalt and chromium after total metal hip replacements, pointing out the urgent need to study the long-term effects of chromium accumulation in the body. This marked the beginning of formal medical research into the impact of metal implant particles or ion release on the human body, and since then, doctors have continuously published articles on this topic.
Cobalt poisoning is not only seen in artificial joints but sometimes also occurs in patients with dental implants because some implants contain cobalt-chromium-molybdenum alloys. Excessive wear can expose the cobalt metal inside, leading to cobalt toxicity.
