To compare the diagnostic accuracy of digital radiography (DR) and cone beam computed tomography (CBCT) in the detection of peri-implant bone defects.
Implants were placed in 5 fresh bovine ribs (3 without peri-implant bone defects, 12 with 1.4mm peri-implant bone defects) and images were taken using (i) portable x-ray system (DEXCOWIN 3000), (ii) intraoral x-ray sensor (SENSOR H1/SENSOR H2), (iii) volume-limited HSCT with 3D Accuitomo 80 (CASTELLINI). Images of each were randomly presented to 10 examiners. Confidence in the diagnosis of the presence or absence of a peri-implant radiolucency was recorded on a scale of bone defect definitely absent, doubts about the defect if absent or present, defect definitely present. Analyzes was performed using a kappa test.
There has been a coincidence between the direct digital radiography and the cone beam computed tomography in piece A of 83.3%, in piece B of 100% and in piece C of 88%, giving an average total coincidence 90.43%. Direct digital radiography provided the same results as cone beam computed tomography in the detection of peri-implant bone defects at an early stage. Digital radiographs are a reliable and valid method and perform significantly better than cone beam computed tomography for detecting peri-implant bone defects at an early stage.
比较数字X线摄影（DR）和锥形束计算机断层扫描（CBCT）在检测种植体周围骨缺损方面的诊断准确性。
将种植体植入5根新鲜牛肋骨中（3根无种植体周围骨缺损，12根有1.4mm种植体周围骨缺损），并使用以下设备进行图像采集：（i）便携式X射线系统（DEXCOWIN 3000），（ii）口腔内X射线传感器（SENSOR H1/SENSOR H2），（iii）使用3D Accuitomo 80（CASTELLINI）的容积受限HSCT。将每组图像随机呈现给10名检查者。根据骨缺损肯定不存在、缺损是否存在存疑、缺损肯定存在的等级记录对种植体周围透射区存在与否的诊断信心。使用kappa检验进行分析。
在A片中，直接数字X线摄影与锥形束计算机断层扫描的符合率为83.3%，在B片中为100%，在C片中为88%，平均总符合率为90.43%。在早期检测种植体周围骨缺损方面，直接数字X线摄影与锥形束计算机断层扫描的结果相同。数字X线片是一种可靠有效的方法，在早期检测种植体周围骨缺损方面的表现明显优于锥形束计算机断层扫描。
