I 2nd what everyone has said, especially about the involvement of your other doctors. Each tooth may receive a different radiation dosage based on your treatment plan, areas of cancer, and not every area has the same blood flow as the mandible had more ORN than the Maxilla on average. It's not like every area receives 70Gy like the primary either, and other areas such as lymphs may receive 54Gy-60Gy, using myself as an example. Many reports say ORN is usually with radiation above 60Gy, although one has said even lower. As far as ORN risk as radiation time goes by, I thought I read it increases with age, but the average is 3 years, as low as 3 months, and a decade later, according to some studies if I recall correctly. I've seen reports of dental implants in radiated patients, and something about "loading" the implant at time of surgery, I hope to attach here.
