To apply high-frequency ultrasound (HFUS) echo intensity for characterizing peri-implant tissues at healthy and diseased sites and to investigate the possible ultrasonographic markers of health versus disease.
Sixty patients presenting 60 implants diagnosed as healthy (N = 30) and peri-implantitis (N = 30) were assessed with HFUS. HFUS scans were imported into a software where first-order greyscale outcomes [i.e., mean echo intensity (EI)] and second-order greyscale outcomes were assessed. Other ultrasonographic outcomes of interest involved the vertical extension of the hypoechoic supracrestal area (HSA), soft-tissue area (STA) and buccal bone dehiscence (BBD), among others.
HFUS EI mean values obtained from peri-implant soft tissue at healthy and diseased sites were 122.9 ± 19.7 and 107.9 ± 24.7 grey levels (GL); p = .02, respectively. All the diseased sites showed the appearance of an HSA that was not present in healthy implants (area under the curve = 1). The proportion of HSA/STA was 37.9% ± 14.8%. Regression analysis showed that EI of the peri-implant soft tissue was significantly different between healthy and peri-implantitis sites (odds ratio 0.97 [95% confidence interval: 0.94-0.99], p = .019).
HFUS EI characterization of peri-implant tissues shows a significant difference between healthy and diseased sites. HFUS EI and the presence/absence of an HSA may be valid diagnostic ultrasonographic markers to discriminate peri-implant health status.
应用高频超声（HFUS）回声强度对健康和患病部位的种植体周围组织进行特征描述，并研究健康与疾病状态下可能的超声标志物。
对60例患者的60颗种植体进行评估，其中诊断为健康种植体（N = 30）和种植体周围炎（N = 30）。采用HFUS对患者进行检查。HFUS扫描图像被导入软件，评估一阶灰度结果[即平均回声强度（EI）]和二阶灰度结果。其他感兴趣的超声检查结果包括龈上低回声区（HSA）的垂直范围、软组织面积（STA）和颊侧骨缺损（BBD）等。
健康和患病部位种植体周围软组织的HFUS EI平均值分别为122.9±19.7灰度级（GL）和107.9±24.7灰度级；p = 0.02。所有患病部位均出现了健康种植体中不存在的HSA（曲线下面积 = 1）。HSA/STA的比例为37.9%±14.8%。回归分析显示，健康种植体部位与种植体周围炎部位的种植体周围软组织EI存在显著差异（优势比0.97[95%置信区间：0.94 - 0.99]，p = 0.019）。
HFUS对种植体周围组织的EI特征描述显示，健康和患病部位之间存在显著差异。HFUS EI以及HSA的有无可能是区分种植体周围健康状况的有效超声诊断标志物。
