Digital subtraction radiography is proposed as a potential diagnostic tool for implant research and patient monitoring. Examples of the application of this technique are given observing peri-implant density changes during the early healing phase and during ligature-induced peri-implantitis in an animal model. Additional cases document the loss of peri-implant bone density associated with an infection and increase in density caused by remodeling after functional loading of an implant with a single crown. Digital subtraction radiography might be one of the most sensitive noninvasive methods for assessing subtle density changes in peri-implant tissues, providing additional diagnostic information on implant tissue integration and maintenance.
数字减影血管造影术被提议作为植入物研究和患者监测的一种潜在诊断工具。给出了该技术应用的示例，观察动物模型中早期愈合阶段以及结扎诱导的种植体周围炎期间种植体周围密度变化。其他病例记录了与感染相关的种植体周围骨密度丧失以及单冠种植体功能加载后重塑导致的密度增加。数字减影血管造影术可能是评估种植体周围组织细微密度变化最敏感的非侵入性方法之一，可为种植体组织整合和维持提供额外的诊断信息。
