| Popis: |
Polysulfide impressions were made at 37 degrees C in two cylindrical trays of a truncated cone-shaped chromium-steel die. One tray size was used to obtain impressions with 1 mm thickness from tray to the gingival margin of the preparation, while the second tray permitted a thickness of 4 mm. Stone dies were made from impressions after (1) cooling to 22 degrees C for 10 min or (2) cooling to 22 degrees C for 10 min and reheating to 37 degrees C for 30 min. Results revealed that reheating impressions to mouth temperature before pouring the dies improved their accuracy. |
