Altered cast Technique: Improving Tissue support for the Distal Extention Bases

Altered cast impression technique is commonly used for the mandibular distal extension partially dentulous arches. The technique is relatively simple but requires increased chair-side time and laboratory cost. Oral tissues that have been displaced during the impression procedure attempt to regain the anatomic form and they may get inflamed if the denture base does not permit them to do so. The aim of this case report is to portray an approach of recording a minimal tissue displacing altered cast impression using addition cured silicone material.
