[Comparative characteristics of microanatomical organization of regional lymph node following the insertion of implants made of different alloys].
The regularities of morphologic transformation of the cervical superficial lymph node were studied following the insertion of implants into mandibular pars alveolaris in the region of molar teeth. Cobalt-chromic alloy, titanium and titanium nickelide were used as implantation materials. The implantation material composition was found to define the character of reactive structural transformations of the lymph node. The insertion of implants made of cobalt-chromic and titanium nickelide alloys resulted in the increase of the total area of lymph node and of its components. Titanium implants were shown to cause the reorganization of internal structure of the lymph node without the alterations of its total area. It is concluded that titanium containing alloys are preferable for implantation.
