title: [Gingival deflection and regeneration after electrotomy].
abstract: In hydrocolloid impressions, the visibility of the margins of cavity preparation is most important. Purely mechanical management of the gingival tissue by cotton threads does not always give satisfactory results, particularly in multiple preparations. Electrosurgery, subtly used, avoids blood and seepage from the sulcus and seems to better control the accessibility of the margins to the hydrocolloid material.
