A Comparison between Two Ways of Relining With Soft Denture Lining Materials (An in-vitro Study)

This study was done to compare two ways of relining with permanent soft denture lining materials. In this study, two types of specimens group-A and group-B were used. Group-A was made by using vacuum formed spacer and Group-B was made without using vacuum spacer [simple conventional method]. After converting, polishing and finishing the specimens, selected tooth areas were relined i.e.11,12,21,22,26,27,31,32,36,37,41,42 for both groups. First, selected tooth areas were cut to maintain 2mm thickness in respected tooth areas. For relining permanent soft denture lining material Molloplast-B was used which was placed on cut tooth region. After relining, completed relined portions were measured with measuring tool (digital calliper) in mm and comparison between two groups was done. Group-A specimens were made using vacuum formed spacer and relined with soft denture lining materials at 11, 12, 21, 22, 26, 27, 31, 32, 36, 37, 41, 42. When thickness was measured with measuring tool, Group-A specimens were less in thickness than Group-B. Within the limitation of this study, it can be concluded that when vacuum formed spacer with permanent soft denture lining material was used, results were more accurate.
