Management of the flabby ridge: using contemporary materials to solve an old problem. Complete Dentures: From Planning to Problem Solving. Oral status and prosthetic factors related to residual ridge resorption in elderly subjects. Clinical morbidity and sequelae of treatment with complete dentures. When deciding upon which technique to use, the clinician must be comfortable with the impression material and produce consistent results.Ĭarlsson G E.
Figure 3 shows a modified window technique impression, whereby light-body PVS (light green) is used to record the flabby tissue, alongside a muco-compressive record of the 'normal' tissue with zinc-oxide eugenol (pink), and functional record of the sulcus, tuberosities and post-dam with impression compound. 4 On the other hand, modern polyvinyl siloxane (PVS) impression materials are now available in multiple viscosities and handling properties, offering a solution to the difficulties associated with traditional impression techniques. 7, 8, 9 Techniques such as the window technique, the use of multiple relief holes, or recording the compressible and displaceable tissue using two separate impression materials and trays, can lead to inaccuracies. The literature describes a number of impression techniques for managing flabby tissue however, their objective to record the displaceable tissue 'at rest' remains consistent.
