- B. applying Xantropren-Function impression material on the whole surface of lower tray and functional shaping of the margins in the presence of upper tray (without impression material).
- C. both impression trays (upper and lower) after applying Xantropren-Function impression material are inserted simultaneously and patient is asked to perform functional movements.
- D. roll made with Xantropren-Function impression material is fixed to the posterior border of upper tray and patient is asked to perform functional movements to seal the A-H line.
- E. fluid Xantropren-Function impression material is applied only on upper tray and patient is asked to perform functional movements.
