After 14 days of healing woven bone, which appears as a loose, unstructured network of bone, has started to fill the socket except in the central region, where significant amounts of the provisional connective tissue matrix still remain. This is because the woven bone forms first at the periphery of the socket and gradually extends from the walls towards the center of the socket. It is characterized by a poorly organized collagen matrix that deposits along the newly formed blood vessels that originated from the surrounding trabecular bone. At this stage most of the bundle bone has been resorbed, and the bone marrow spaces in the interdental septa communicate directly with the newly formed bone.
