This research aimed to analyze the differences in bone density and bone morphometry by periapical implant radiography in the dental implant osseointegration stages.
This experimental research uses 12 periapical radiographs of tibial bones from a New Zealand white rabbit (). The analysis was performed on day 3, 14, and 28 of the osseointegration stages with density, trabecular thickness (Tb.Th.), trabecular separation (Tb.Sp.), and trabecular number (Tb.N.) as parameters. The implant used is a titanium alloy and coated by SA (sunblasted with alumina acid) of 4 mm in diameter and 7 mm in length. The radiographic assessment of the osseointegration process is obtained with the region of interest (ROI) segmentation results. Additionally, each ROI was analyzed for bone density and morphometry using the open-source ImageJ software with the BoneJ plugin. The significant difference was evaluated by analysis of variance (-test) with < 0.05 and nonparametric Kruskal-Wallis test with < 0.05.
Analysis of the osseointegration images of dental implants at day 3, 14, and 28 with the periapical X-ray modality shows significant differences ( < 0.05) in the parameters measuring density and trabecular thickness (Tb.Th.). In the variables of trabecular separation (Tb.Sp.) and number (Tb.N.) ( > 0.05), there is no significant difference.
Based on the results, density and trabecular thickness (Tb.Th.) showed a significant difference between healing times. However, trabecular separation (Tb.Sp.) and trabecular number (Tb.N.) showed no difference in healing time.
本研究旨在通过根尖片分析牙种植体骨结合阶段的骨密度和骨形态计量学差异。
本实验研究使用了一只新西兰白兔的12张胫骨根尖片。在骨结合阶段的第3天、第14天和第28天进行分析，以密度、骨小梁厚度（Tb.Th.）、骨小梁间距（Tb.Sp.）和骨小梁数量（Tb.N.）为参数。所使用的种植体为钛合金材质，直径4毫米，长度7毫米，表面经SA（用氧化铝酸喷砂处理）涂层。通过感兴趣区域（ROI）分割结果获得骨结合过程的影像学评估。此外，使用带有BoneJ插件的开源ImageJ软件对每个ROI进行骨密度和形态计量学分析。通过方差分析（-检验），P<0.05以及非参数Kruskal-Wallis检验，P<0.05评估显著差异。
使用根尖X线片模式对牙种植体在第3天、第14天和第28天的骨结合图像进行分析，结果显示在测量密度和骨小梁厚度（Tb.Th.）的参数上存在显著差异（P<0.05）。在骨小梁间距（Tb.Sp.）和数量（Tb.N.）变量方面（P>0.05），没有显著差异。
基于结果，密度和骨小梁厚度（Tb.Th.）在愈合时间之间显示出显著差异。然而，骨小梁间距（Tb.Sp.）和骨小梁数量（Tb.N.）在愈合时间上没有差异。
