摘要
目的探讨纵向断层程序p23的投照技术在上颌多生牙位置判断的应用价值。方法选取60例经曲面断层,头影测量侧位或根尖片诊断为上颌前牙区多生牙的患者,应用纵向断层程序p23投照,分析多生牙的准确位置,并与多生牙拔除术中所见对比。结果应用纵向断层程序中的p23定位多生牙60例患者,其中偏唇侧24例,偏腭侧31例,居中5例,患者多生牙方向的诊断与手术中所见一致,准确率为100%。结论纵向断层程序p23是上颌前牙区多生牙诊断中直接有效的方法。
Objective To investigate the application value of longitudinal imaging program 23 of panoramic tomography in judging the position of additional teeth in maxillary anterior region.Methods The positions of 60 additional teeth diagnosed by panoramic tomography or apical films were located with longitadinal imaging program 23.And the results were compared with the findings of the surgery.Results The diagnosis results of longitudinal imaging program 23 for additional teeth in maxillary anterior region were consistent with the results of surgery.The accurate rate was up to 100%.Conclusion Logitudinal imaging program 23 is an effective method for the location of the additional teeth in maxillary anterior region.
