Ultrasonography has shown its promising diagnostic value in dental implant imaging research in the three treatment phases, namely, planning, intraoperative, and postoperative phase. With increasing awareness of peri-implant diseases and a lack of an efficient diagnostic method, the aim is to propose ultrasound imaging as a potential solution by providing a detailed scanning protocol and case demonstration.
Ultrasound device specification and the setup for optimizing peri-implant tissue imaging was described. Two useful imaging modes, viz. B-mode and color flow, were introduced. Important anatomical structures for accurate diagnosis of peri-implant diseases were illustrated. Finally, a detailed scanning sequence was proposed.
Ultrasound images were acquired on live humans to exemplify the four peri-implant diseases and conditions, endorsed by the 2017 World Workshop organized by the American Academy of Periodontology and the European Federation of Periodontology. Ultrasound can provide not only cross-sectional anatomical images but also functional images (color flow images) that may be useful for evaluating the degree of peri-implant tissue inflammation.
High-frequency ultrasonography could be another cross-sectional imaging modality in adjunct to radiographs for diagnosing imminent peri-implant diseases and conditions that negatively influence quality of life of millions of patients with implants. This case study provides a framework for future related research work and clinical scanning guidelines.
超声检查在种植体治疗的三个阶段（即规划、术中及术后阶段）的影像学研究中显示出了有前景的诊断价值。由于人们对种植体周围疾病的认识不断提高，而缺乏有效的诊断方法，因此旨在通过提供详细的扫描方案和病例演示，提出超声成像作为一种潜在的解决方案。
描述了超声设备的规格和优化种植体周围组织成像的设置。介绍了两种有用的成像模式，即 B 模式和彩色血流模式。阐述了用于准确诊断种植体周围疾病的重要解剖结构。最后，提出了详细的扫描序列。
在活体人身上获取了超声图像，以举例说明 2017 年由美国牙周病学会和欧洲牙周病学会组织的世界牙周病研讨会认可的四种种植体周围疾病和状况。超声不仅可以提供横断面解剖图像，还可以提供功能图像（彩色血流图像），这可能有助于评估种植体周围组织炎症的程度。
高频超声可能是另一种与射线照相术联合使用的横断面成像方式，用于诊断可能影响数百万种植体患者生活质量的种植体周围疾病和状况。本病例研究为未来的相关研究工作和临床扫描指南提供了框架。
