Step 2: Positioning
Now forcefully press the tray filled with putty and covered by the foil onto a dental model. Keep the tray in place by equally and centrically applied constant pressure, so the foil and the putty will surround the teeth – use two fingers in the maxilla on each side and one thumb in the mandible on each side. Push back any putty that spread past the tray with the dental mirror towards the last teeth to be moulded.
