Abstract

Background:  The final impression obtained during a complete denture building involves capturing the vestibule along with the border molding technique and then obtaining an impression of the edentulous area. The present study was conducted with the aim to establish the retention force of different impressions made with two different techniques. Materials and methods: The present study was conducted in the Department of Prosthodontics. The study enrolled a total of 8 subjects between the age of 50-60 years that had well-formed residual alveolar ridges. Custom made impression trays were obtained using acrylic resin. For each subject two trays were made, and the trays were kept short by 2-3 mm. Border molding of the first tray was done using sectional technique with the help of impression compound.  All the information obtained was arranged in a tabular form and analyzed using SPSS software. Student t test was used as a test of significance. Probability value of less than 0.05 was regarded as significant. Results: In case 8 the mean retentive force by single step technique was 9.91 and with sectional technique was 9.56. The overall mean retentive force in single step was 8.39 and in sectional step was 9.17. Conclusion: According to our study, the sectional border molding procedure seemed to provide more retention than single step procedure.
