Abstract

Purpose: This study was undertaken to compare the retention between sectional border molding using low fusing greenstick compound and single step border molding using condensation silicone (putty) impression material in two stages- A. After final impression and B. With the temporary denture base. Materials & Methods: In this study evaluation of retentive values of sectional border molding (Group I) (custom impression trays border molded with green stick compound ) and single step border molding (Group II) ( border molding with condensation silicone (putty) impression material ). In both techniques definitive wash impression were made with light body condensation silicone and denture base with auto- polymerization resin. Results: Group 1B was significantly higher (mean- 2.176) than Group 1A (mean- 1.798) in test-1. The t-value (6.023) infers that there was significant difference between Group 1A and Group 1B (p =0.001). Group 2B was significantly higher (mean- 2.344) than Group 2A (mean-2.111) in test -2. The t-value (2.852) infers that there was significant difference between Group 2A and Group 2B (p=0.001). Conclusion: Within the limitations of this clinical study border molding using custom tray with low fusing green stick compound provided significant difference for retention as compared to condensation silicone at border moulding and denture base stage.
