The electric characteristics were lowered or absent in 87 patients wearing removable metal-based dentures. The explanation is as follows: in patients with plastic plate dentures and permanent metal prostheses in the oral cavity the electric charges pass between the prostheses via the saliva and oral tissues; in patients with metal-based plate dentures the charges pass along the metal basis, which fact is due to high electric conductivity of metal. Therefore in patients with plastic removable dentures the electric charges have a more detrimental effect on the oral tissues.
87名佩戴可摘金属基假牙的患者出现了电特性降低或消失的情况。原因如下：在口腔中有塑料板假牙和永久性金属假体的患者中，电荷通过唾液和口腔组织在假体之间传递；在佩戴金属基板假牙的患者中，电荷沿着金属基底传递，这是由于金属的高导电性。因此，对于佩戴可摘塑料假牙的患者来说，电荷对口腔组织的危害更大。
