The common microscopic findings included irregular or jagged alveolar bone margins
with Sharpey's fibers inserting irregularly into the woven bone.
Similarly, the distance laterally was evaluated by Nagadia et al., who, in a study done with tomography images, measured the distances between the buccal bone margin
and the mandibular canal, indicating that at the level of the lower first molar, this distance varies between 3.71 and 6.91 mm with an average of 5.44 mm.
Use of intraoperative radiographs has been advocated for confirmation of bone margins
At regular intervals, radiological follow-up examinations were carried out by means of CT, which documented the new formation of the sacrum, including the neuroforamina, initially as a thin bone margin
in the area of the former sacrum up to the formation of a new sacrum (Figure 7).
Blood vessels (arterioles and venules) were not regularly placed along the bone margin
as in group B.
The etiology might be of non inflammatory disease conditions which included degenerative joint disease and osteoarthritis, characterised by degeneration of the articular cartilage, hypertrophy of the bone margin
and changes in the synovial membrane which might be primary due to aging or secondary due to developmental diseases.
This surgical procedure involves raising full thickness buccal and lingual flaps and placing vertical osseous grooves extending from just below the interproximal alveolar bone margin
to beyond the apices of the teeth and then horizontal grooves to connect the vertical cuts.
