Bone invasion

Bone invasion

Three patterns of bone invasion, namely infiltrative, erosive or mixed, have been described. There is strong evidence that most tumours enter the bone at the point of contact in an erosive fashion, and not via foramina or the periodontal membrane. It is important to point out that cortical erosion as opposed to medullary invasion does not equate to a T4 tumour. Bone invasion
