But in cases of generalized flabbiness of the residual ridge, even the manual placement and manipulation of a custom tray may distort the tissues, violating the principle of mucostatics. Mucostatic or Passive Impression First proposed by Richardson and later popularised by Harry Page. The posterior Group IV two step window mucostatic tray part was returned to the cast and double impression technique: The impression procedure thickness of wax spacers were adapted on the palatal for this technique was carried out following the aspect of the flabby ridge and extending to the crest. Boucher’s technique: 1 mm wax relief is given over the entire basal area of thecustom tray, tray is trimmed 2-3 mm short of the peripheral extensions, border molding is done, periphery is again trimmed 1 mm short, wax removed to provide space for wash impression material.
