| 摘 要： | 目的：提出一种以种植体为参照用于曲面体层片后牙区局部测量的方法，并对其误差进行分析。方法：收集2017年1月~2018年1月于南京医科大学附属口腔医院种植科就诊的奥齿泰种植修复病例曲面体层片。预先记录种植体和覆盖螺丝的尺寸，利用种植体参照法测算覆盖螺丝的高度与直径，比较测算值与实际值，分析该方法的绝对误差。结果：54例患者，共93张曲面体层片被纳入本研究。数据样本符合正态分布，测算值与实际值之间无显著性差异。应用种植体参照法进行后牙区测量的垂直向和水平向绝对误差均小于0.1 mm。结论：种植体参照法应用于曲面体层片后牙区局部测量具有可行性，测量精度较高。

| Abstract: | Objective: To provide an implant reference method in measurement of posterior teeth region in the panoramic radiograph, and analyze the measurement error. Materials and Methods: From January 2017 to January 2018, panoramic radiographs of patients who received Osstem implant restoration treatments were collected at the Department of Implantology of Affiliated Hospital of Stomatology of Nanjing Medical University. The sizes of dental implants and cover screws were recorded in advance. The heights and diameters of the cover screws were calculated using the implant reference method. The calculated values were compared with the actual values to analyze the errors of this method. Results: Totally 93 panoramic radiographs from 54 patients were included in this study. The data sample accorded with normal distribution and there were no significant differences between the calculated values and actual values. Both vertical and horizontal absolute errors of measurements of posterior teeth regions in the panoramic radiographs using the implant reference method were less than 0.1mm. Conclusions: The implant reference method is applicable to the local measurement of the posterior region in the panoramic radiograph, and the measurement accuracy is relatively high. |
