Furthermore, the possibility of evaluating the biological quality of the resection surface by examining the percentage of sclerotic bone in the most distal cut surface of the bony specimen was analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A new method to evaluate bony resections using a three-dimensional Computer-Aided Design model could be implemented.
