Palatal vent holes may be used in the tray to reduce pressure and allow the escape of air and excess material.\nOnce the custom tray is ready, the clinical steps for taking the impression (using a material such as Polyether) generally include:\n\nMaterial Preparation and Loading: Add the impression material (e.g., Impregum Soft) into the tray, remembering that only a small amount is required.\nSpreading: Spread the material evenly to avoid air bubbles.\nMargin Coverage: Ensure that the material is extended onto the tray margins.\nSeating: Seat the tray in the mouth from the posterior forward to reduce the risk of aspiration.\nExcess Removal: Remove any excess material using a dental mirror head; suction should be used if there is an imminent aspiration risk.\nBorder Moulding: The impression technique includes border moulding, which captures the peripheral tissues.\nPost-Set Evaluation: Once the impression material has set, separate the tray from the model.\nChecking and Trimming: Check the impression for defects like “burn through” and trim any excess material with a scalpel or scissors.\nClinical Check (if applicable): For clinical cases, reinsert the completed impression to check retention and stability.” } ] }
