螺旋CT骨密度测定对种植前牙槽骨骨质的评价
目的对临床种植义齿患者术前行颌骨三维CT影像学检查,探讨影像学检查对临床牙槽骨骨质分类的指导意义。方法选取将行种植义齿治疗的患者作为受测者,对其术前感兴趣区应用多层螺旋CT扫描进行牙槽骨CT灰度值及Marker横截面的灰度值测量。结果①ⅠⅣ类骨质分类的CT平均骨密度相对灰度值不同（F〉1,P〈0.05）;②上颌前后牙区、下颌骨前后牙区CT平均骨密度相对灰度值有明显差异,且下颌前牙区骨密度值最大（F〉1,P〈0.05）;③男女性别在骨质分类上无统计学差异（P〉0.05）;④年龄段分组比较中差异有统计学意义（F〉1,P〈0.05）,且3039岁的骨密度灰度值最大。结论多层螺旋CT的相对骨密度灰度值...

| Summary: | 目的对临床种植义齿患者术前行颌骨三维CT影像学检查,探讨影像学检查对临床牙槽骨骨质分类的指导意义。方法选取将行种植义齿治疗的患者作为受测者,对其术前感兴趣区应用多层螺旋CT扫描进行牙槽骨CT灰度值及Marker横截面的灰度值测量。结果①ⅠⅣ类骨质分类的CT平均骨密度相对灰度值不同（F〉1,P〈0.05）;②上颌前后牙区、下颌骨前后牙区CT平均骨密度相对灰度值有明显差异,且下颌前牙区骨密度值最大（F〉1,P〈0.05）;③男女性别在骨质分类上无统计学差异（P〉0.05）;④年龄段分组比较中差异有统计学意义（F〉1,P〈0.05）,且3039岁的骨密度灰度值最大。结论多层螺旋CT的相对骨密度灰度值可以客观评估种植前的骨质情况。 |

Implantation Center of the Affiliated Stomatology Hospital, Medical School of Xi＇an Jiaotong University, Xi＇an 710004, China） Objective To make a preoperative imaging examination on the jaw of dental implantation patients to explore the value of imaging examination in guiding clinical classification of the alveolar bone.Methods Patients for false tooth implantation were recruited as subjects.Multi-slice spiral CT（MSCT） was used to scan the regions of pre-implantation interest to measure the relative gray value of alveolar bone mineral density（BMD） and the gray value of Marker cross-section.Results ① The results of BMD of bone classification Ⅰ-Ⅳ were different（F〉1,P〈0.05）.② BMD differed significantly among the maxillary anterior and posterior regions,mandible anterior and posterior regions,with the mandible anterior region having the |
