Dolphin imaging cephalometric3/31/2024 ![]() A Friedman test was applied to examine for differences. Additionally, 61 patient records were used to compare the digital method for best-fit cranial base superimpositions versus S-N superimpositions. Linear distance between multiple cor-responding (hand and digital) T2 cephalometric landmark locations (e.g., A point) were measured and defined as the T2 landmark distance (T2 LD). To quantitatively evaluate the differ-ences between the two methods, the hand and digital superimpositions were digitized to obtain x-y coordinates of routine cephalometric landmarks at T2. Cranial base and regional superimpositions were completed independently for each pair of radiographs by either hand tracing and digital methods. Methods and Materials: Sixty-four initial (T1) and final (T2) cephalometric film radiographs were obtained. In addition, if the two methods were comparable, we wanted to determine if a difference existed between the best-fit cranial base superimposition and S-N superimpositions using the digital method. Objective: To determine the ability to produce comparable superimpositions using hand tracing and digital methods (Dolphin v10). ![]()
