本研究的目的是探讨超声（US）用于种植体周围组织临床成像的可行性。纳入了植入≥ 1个植入物、CBCT扫描、US扫描和手术期间拍摄的临床照片的患者。在US和CBCT模式上测量牙槽嵴骨厚度（CBT）和面骨水平（FBL），并在临床图像上直接测量FBL。将US测量结果与CBCT和直接读数进行比较。共纳入4例患者的8个种植体。对于FBL测量，US和直接（r2=0.95）以及US和CBCT（r2=0.85）高度相关，而CBCT与直接阅读（r2=0.75）的相关性令人满意。在一个没有面骨的种植体中，CBCT无法准确测量CBT和FBL。US和CBCT之间CBT读数的估计偏倚为0.17 ± 0.23 mm（p=0.10）。超声血流成像被成功记录，并显示了不同程度的临床炎症患者的宽动态范围。超声是一种可行的方法来评估种植体周围的面嵴骨的尺寸。其他美国功能，例如，功能性血流成像可能有助于估计炎症的范围和严重程度。
The aim of the present study was to explore the feasibility of ultrasonography (US) for clinical imaging of peri-implant tissues. Patients with ≥ 1 implant, a CBCT scan, an US scan, and clinical photographs taken during the surgery were included. The crestal bone thickness (CBT) and facial bone level (FBL) were measured on both US and CBCT modalities, and direct FBL measurements were also made on clinical images. US measurements were compared with CBCT and direct readings. A total of 8 implants from 4 patients were included. For FBL measurements, US and direct (r2=0.95) as well as US and CBCT (r2=0.85) were highly correlated, whereas CBCT correlated satisfactorily with the direct reading (r2=0.75). In one implant without facial bone, CBCT was not able to measure CBT and FBL accurately. The estimated bias for CBT readings was 0.17 ± 0.23 mm (p=0.10) between US and CBCT. US blood flow imaging was successfully recorded and showed a wide dynamic range among patients with different degrees of clinical inflammation. US is a feasible method to evaluate peri-implant facial crestal bone dimensions. Additional US features, e.g., functional blood flow imaging, may be useful to estimate the extent and severity of inflammation.
