What temperature is detrimental to bone when placing an implant?

The critical temperature threshold that is detrimental to bone during the placement of an implant is 47 degrees Celsius. When temperatures exceed this limit, it can lead to thermal necrosis of the bone, which affects the healing process and may compromise the integration of the implant.

At temperatures of 47 degrees Celsius and above, the biological processes in the bone tissue can be negatively impacted, leading to decreased viability of the osteoblasts and other bone cells. This can hinder osseointegration, the process by which an implant becomes securely anchored in the bone, and may increase the risk of implant failure.

While temperatures of 45 degrees Celsius may cause temporary changes in bone metabolism, they are generally considered to be within the safe range for surgical procedures involving implants. Higher temperatures, such as 50 degrees Celsius and 55 degrees Celsius, would significantly increase the risk of bone injury and would not be tolerated during implant placement. Therefore, maintaining a temperature below 47 degrees Celsius is crucial for successful surgical outcomes and bone health.
