Cone-beam CT로부터 시뮬레이션된 측모 두부계측방사선사진의 정확도

다국어 초록 (Multilingual Abstract)

The 3-dimensional approaches for the diagnosis and analysis of the dentofacial area are becoming more popular in accordance with the development of cone-beam CT (CBCT). The purpose of this study was to evaluate the reliability of the measurements of the lateral cephalometric radiograph simulated from CBCT by comparing with the digital lateral cephalometric radiograph, and to evaluate the possibility of the clinical application of the lateral cephalometric radiograph simulated from CBCT. 20 patients whose soft tissue external auditory meatus could be identified in CBCT images were selected, and both the CBCT and digital lateral cephalometric radiographs were taken. Differences between the measurements of both the lateral cephalometric radiographs were tested by paired t-test. Among the 23 measurements used, only U1-FH, Mx6 to PTV, maxillomandibular difference showed statistically significant differences between the CBCT and digital lateral cephalometric radiographs. In conclusion, the lateral cephalometric radiograph simulated from CBCT can be used for some cephalometric measurements not using porion, PTV, condylion as a landmark.
