Using hyperbaric oxygen therapy for dental implants in irradiated bone is recommended primarily to enhance wound healing. In patients who have undergone radiation therapy, the irradiated bone exhibits compromised oxygenation and reduced blood supply, which can significantly impair the healing process following surgical interventions like dental implants.

Hyperbaric oxygen therapy involves breathing pure oxygen in a pressurized environment, which increases the amount of oxygen dissolved in the blood plasma. By elevating tissue oxygen levels, it helps stimulate angiogenesis (the formation of new blood vessels), promotes fibroblast function, and enhances collagen synthesis. These biological processes contribute to improved wound healing, especially in compromised tissues such as those found in irradiated bone.

In the context of dental implants, effective healing is crucial for successful integration of the implant with the surrounding bone. By ensuring that the environment is conducive to healing through improved oxygenation, hyperbaric oxygen therapy supports better outcomes for patients undergoing dental implant procedures in areas affected by prior radiation therapy.
