CBCT images and dental models were registered and fused to obtain landmark coordinates of the integrated models. On the midsagittal plane, maxillary arch was fitted separately on each side using clinical crown center points, indices reflecting maxillary arch morphology were measured. Generalized estimating equations (GEEs) and additional statistical analyses were employed to examine the relationship between maxillary arch curvature and its influencing factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The gingival-directional intersection angle between the anterior and posterior segments of the maxillary arch in the sagittal plane (AC\/PC) was smaller in adolescents (162.42\u00b0 \u00b1 6.38\u00b0) than adults (166.09\u00b0 \u00b1 6.93\u00b0).
