“A novel impression technique for recording bilateral severe undercuts with rigid impression materials in completely edentulous patients”
Journal Title: International Dental Journal of Student Research - Year 2016, Vol 4, Issue 3
Abstract
Completely edentulous patients who present hard tissue undercuts along with overlying soft tissue, especially after extraction of proclined natural teeth find their treatment prosthesis deferred for months, especially in situations where one has limited access to elastomeric impression materials. Hard tissue undercuts intensify retention of the prosthesis obtained biologically and are the most commonly available mechanical means of retention in completely edentulous patients. Hard tissue undercuts that range from moderate to severe are often referred by a prosthodontist for surgical correction, as they cannot be recorded using rigid impression materials without altering the design of the final prosthesis. A final impression technique that suffices the advantages of rigid impression materials and prevents surgical intervention for managing hard tissue undercuts in such cases needs to fulfill all the principles of impression making, besides fulfilling the objectives of primary or final cast fabrication. This article in the form of a clinical case report presents a novel final impression technique that is based on the principle of dual impression making and requires simple modification of the custom tray. The technique being simple and inexpensive is indicated in completely edentulous situations with bone and soft tissue undercuts that are contraindicated for surgery.
