Impression making for a completely edentulous situation is a vital step to ensure a good denture prognosis. However in day to day clinical practice, apart from routinely found completely edentulous cases, there are special edentulous situations like advanced mandibular ridge resorption, flabby tissue in the edentulous area, patients with reduced mouth opening and post on co surgery completely edentulous patients, which pose a great amount of difficulties and challenges during the impression making.
