“Grab the flab” window impression technique: A case report

Abstract

Aims and objective: Making of a definitive, secondary or wash/final impression of displaceable flabby tissues with minimum or no displacement of tissue by using window impression technique. Background: Denture fabrication on flabby ridges is testing situations for a clinician as it adversely affects retention and stability of complete dentures. The difficulties encountered in these patients need to be overcome by modified techniques in denture fabrication that are not time consuming and make use of materials that are easy to use. Materials and Methods: This window impression technique, uses a custom tray with a window over flabby tissues and a mucostatic impression material to minimize distortion of tissues while making a impression. First, an accurate record of the denture supporting and limiting structures is made except for the mobile tissues which are recorded in second step using light body Polyvinyl siloxane impression material in the window area of special tray. Conclusion: The use of window impression technique helps in maintaining the contour and recording the details of the tissues without displacing the flabby tissues. Hence, it improves the prognosis for complete denture without surgical removal of hyperplastic tissues.

“…Se toma en un solo tiempo, evitándose distorsiones por presión y/o malposición de la cubeta. La silicona no escurre por gravedad, a diferencia de la técnica clásica "de ventana" que comprende tres pasos y más materiales, entre ellos pasta zinquenólica y /o yeso parís de difícil manejo, el cual debe ser sostenido por el operador para que no escurra por la ventana hasta su fraguado; pudiendo producirse distorsiones del material y de la posición tisular (7)(8)(9) . La modalidad con cubeta multiperforada puede distorsionar el RM ya que la magnitud de presión hidráulica generada es difícil de controlar, pues depende del número, diámetro y ubicación de los orificios; así como de la consistencia del material de impresión (1-12-13) .…”
