Cone beam computed tomography (CBCT)\u2010based digital measurements validated an odontosection depth of 9\u2009mm through the distomarginal ridge at a 75\u00b0 angle to the occlusal plane for the Cross\u2010sectioning protocol. The Cross\u2010sectioning protocol involved dividing the tooth into four segments (distolingual, mesiolingual, mesiobuccal, distobuccal) for sequential removal, whereas the Traditional method involved bifurcation with root extraction before crown.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The Cross\u2010sectioning group demonstrated significantly shorter operation times, reduced postoperative pain, and swelling compared to the traditional group (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.01).
