  • transepithelial separator devices are common in those cases where a dental implant placed on a patient has become very subgingival, that is, under the gum.

  • the known transepithelial separating devices therefore have the function of generating a vertical space in the area of the gum located on the previously placed dental implant, in order to save the height of the gum, that is, to raise the prosthetic connection base of so that it is located above the gum.
