摘　　要：目的:探讨多平面重建技术在牙种植术前评估上颌后牙区骨量情况的临床价值。方法:对62例(98侧)上颌后牙区缺牙患者术前行螺旋CT扫描传入后处理工作站进行多平面重建技术成像后,对15项相关检查项目全面地分析上颌后牙区剩余骨量情况并进行判断是否为牙种植的适应证,同时摄曲面断层片进行对比研究。结果:在术前15项检查项目中,多平面重建技术均可准确地评估,曲面断层片仅有10项可以评估,5项无法评估;在11项非适应证指标中,多平面重建技术均可准确判断,曲面断层片仅有7项可以判断,4项无法判断;对98侧上颌后牙区牙缺失进行判断是否符合非适应证指标中,多平面重建技术的检出率约39.40%,曲面断层片的检出率约20.41%,二者存在显著性差异(P<0.05)。结论:多平面重建技术可准确地评估上颌后牙区术前骨量情况及判断手术适应证,辅助手术方案设计。Objective： To explore the clinical value of the technique for multiple plane reconstruction in pre-operative assessment during dental implantation in maxillary posterior region. Methods： the maxillary posterior teeth from 62 cases （98 sides） were performed a spiral CT scanning preoperatively. After re-constructing the images from multiple planes, the bone of maxillary posterior teeth were analysised whithin 15 related examination projects to evalute whether it is suitable to dental implant surgery. A comparative study was then progressed on the basis of the orthpantomography. Results： The assessment could be accurately achieved with multiple-plane reconstruction in all of the 15 items, while only 10 could be achieved with the panoramic radiographs. In 11 non-indication index, multiple plane recon-struction technique could be well used, while only 7 could be assessed with the orthpantomography. the detection rate of the non indication index is about 39.40%, and the orthpantomography is 20.41%, in the assessment with 98 sides of maxillary anterior teeth. Significant differents could be noted between the both rates above （P〈0.05）. Conclusion： Multiple-plane reconstruction technique may accurately assess maxillary posterior teeth, and thus judging the indications for operation and providing more help for the design of the surgical procedure.
