Dental implants currently in use are mainly made of titanium or titanium alloys. As these metallic elements are immersed in an electrolytic medium, galvanic currents are produced between them or with other metals present in the mouth. These bimetallic currents have three potentially harmful effects on the patient: micro-discharges, corrosion, and finally, the dispersion of metal ions or their oxides, all of which have been extensively demonstrated in vitro. In this original work, a system for measuring the potentials generated in vivo is developed. Specifically, it is an electrogalvanic measurements system coupled with a periodontal probe that allows measurement of the potentials in the peri-implant sulcus. This device was tested and verified in vitro to guarantee its applicability in vivo. As a conclusion, this system is able to detect galvanic currents in vitro and it can be considered capable of being employed in vivo, so to assess the effects they may cause on dental implants.
目前使用的牙种植体主要由钛或钛合金制成。由于这些金属元素浸入电解质介质中，它们之间或与口腔中存在的其他金属会产生电流。这些双金属电流对患者有三种潜在的有害影响：微放电、腐蚀，最后是金属离子或其氧化物的扩散，所有这些在体外都已得到广泛证实。在这项原创工作中，开发了一种用于测量体内产生电位的系统。具体来说，它是一种与牙周探针耦合的电偶测量系统，可测量种植体周围龈沟中的电位。该装置在体外进行了测试和验证，以确保其在体内的适用性。总之，该系统能够在体外检测电偶电流，并且可以认为能够在体内使用，以便评估它们可能对牙种植体造成的影响。
