Abstract
This article describes the making of a functional primary impression for severely resorbed mandibular ridge type IV. In this technique metal wire of 1.5 mm diameter was adapted on the ridge of a mandibular arch from one retromolar pad to another retromolar pad. On the metal wire addition silicone putty was adapted and phonetics was used for making an initial primary functional impression. The prepared initial primary functional impression was under extended. Thus correction was done by adding putty addition silicone impression material. Later wash impression was made using addition silicone light-bodied impression material. The prepared impression was accurate in term of reproduction of details, and in term of extensions it was a functional impression. An impression was not deformed by the manipulations done by the dentist or by using oversized or undersized stock trays.
