Objective To study the variations of the measurement data of the facial height and mandibular position between the patients with edentulous jaws and the people with normal occlusion by means of cephalometric roentgenography. 目的采用X线头影测量方法,研究无牙颌患者与正常牙合人间面部高度、下颌位置等有关测量数据的差异。
Objective To evaluate the dental facial symmetry in normal Shanghai adults occlusion with posterioanterior cephalometric roentgenography. 目的对上海地区正常牙合成人牙、颌、面的对称性作评价。
Conclusion: For the advantages that traditional orthopantomography and cephalometric roentgenography can not possess, the digital orthopantomography and cephalometric roentgenography provide a new way for stomatological research and clinical application. 结论:曲面断层片、头影测量片数字化X线摄影技术具有传统曲面断层片、头影测量片摄影技术所不具备的优越性,因而为口腔临床及科研提供了一种新的检查手段。
