Crowns were designed using a standardized digital workflow with a 50\u2010\u03bcm cement space and cemented with a radiopaque dual\u2010cure resin cement. Marginal and internal gaps were assessed by micro\u2010computed tomography using linear measurements from coronal and sagittal sections at 18 predefined locations. Non\u2010parametric statistical analyses were performed (\u03b1\u2009=\u20090.05), and correlations between marginal and internal gap values were evaluated.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Significant differences were identified among manufacturing techniques at selected marginal and internal locations (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.005 to\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.047).
