[Impression method in patients with maxillo-facial loss with reduction of the degree of oral opening].

The article describes a method for obtaining an impression in patients suffering from a loss of maxillo-facial structure with reduced oral aperture. This involves making an individual resin tray, which is then divided in two, with four plugs on the underside for precise re-alignment later. The method suggested facilitates the insertion and removal of the tray. Thus an accurate impression of the perimeter can be obtained without the risk of trauma.
