“…The handle works as a suctioning device for the patient and has the advantage of being removable on lower trays, facilitating the full and accurate impression of the sub-lingual flange region. To obtain a proper impression of this area, it is important to pay close attention to the normal posture of the tongue (2,10,18,19) and it is necessary to seat the tray correctly, avoiding any dislocation during tongue movements. This can be achieved by removing the handle and holding the tray in place by pressing both lateral acrylic supports.…”

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 develop functional impressions for complete dentures using the patient-conducted muscular motion technique. In upper trays, the handle is fixed in the midline with acrylic resin, while in lower trays 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, is reusable, can be adapted to any individual acrylic resin trays and allows accurate registration of the peripheral sealing zone (border tissues).

“…The use of an individual tray is necessary for this technique. The borders of this tray should be established in such a way that the patient's muscular movements are free from them during the impression procedure (9,10).…”
