CBCT三维头影测量常用指标的初步探索

Abstract

Abstract: Objective: To study the relevance of the results of the commonly used indicators of the cephalometric measurement obtained from the three-dimensional (3D) transformation lateral cephalometric radiograph and the three-dimensional cone-beam computed tomography (3D CBCT). Methods: To choose 100 malocclusion patients who fit the inclusion criteria, to do the cephalometric analysis with 2D and 3D methods, and to analyze the difference and the fitting degree between the two methods. Results: The differences between the two cephalometric analysis measurements were statistically significant (P <0.05), 7 indexes had the good fitting and 1 index had the moderate fitting. Objective: To explore preliminarily the application of three-dimensional cephalometric measurement of CBCT by studying the relevance ofthe results of the commonly used indicators of the cephalometric measurement obtained from the three-dimensional (3D) transformation lateral cephalometric radiograph and the three-dimensional cone-beam computed tomography (3D CBCT).Methods: To choose 100 malocclusion patients who fit the inclusion criteria, to do the cephalometric analysis with 2D and 3D methods, and to analyze the difference and the fitting degree between the two methods.Results: The differences between the two cephalometric analysis measurements were statistically significant (P <0.05), 7 indexes had the good fitting and 1 index had the moderate fitting. There was the correlation between the two cephalometric analysis measurements. Conclusion:The results of the commonly used indicators of the cephalometric measurement obtained from the 3D CBCT can reflect the maxillofacial morphology in patients with malocclusion.The establishment of standardized fixed-point and normal value database of three-dimensional cephalometric measurement needs to be further studied and established.

Key words: CBCT（cone-beam computed tomography）, cephalometric measurement, malocclusion, maxillofacial morphology
