Abstract

This report describes the use of a removable acrylic resin tray handle that can be easily attached to custom impression trays to produce an improved peripheral sealing zone. This device can be indicated to achieve functional impressions for complete dentures using the patient-conducted muscular motion technique. In the upper tray, the handle is fixed in the midline with acrylic resin, while in lower tray the centrally positioned handle is removed before border molding. This removable handle allows patient's suction and free tongue movements. Final impression is carried out in two stages: peripheral sealing (low fusion compound) and recording of the main supporting region of the denture (zinc oxide and eugenol paste). All border records are obtained from the patient's own movements (handle suction and tongue motion). The removable handle is simple to use, reusable, easily adapted to individual acrylic resin trays and allows accurate registration of the peripheral sealing zone (border tissues).
