| description | Background and objectives: The choice of impression technique and material can influence the accuracy of the final prosthesis. This study aims to assess the impact of two impression methods and materials on denture retention.
Methods: This non-randomized clinical trial was carried out on 30 fully edentulous patients in the College of Dentistry and in Duhok Dental Polyclinics from October 1, 2022, to June 30, 2023. For each participant, two sets of maxillary impressions were taken. The first impression was done with zinc oxide eugenol impression paste and green stick compound for border molding by using a special tray, and the second impression was completed with polyvinyl siloxane impression material on a stock tray using the putty-wash technique. Two stone casts were made for each participant, and two denture bases with wire loops in the middle were fabricated. Using a digital force gauge, the intra-oral retention force was evaluated in both groups.
Results: The denture base fabricated with polyvinyl siloxane impression material had a mean retention value of 3.88 kg and 3.89 kg for males and females, respectively, while the mean retention value of zinc oxide eugenol paste for males and females was 3.63 kg and 3.72 kg, respectively, with a p value of 0.3518. The difference was non-significant.
Conclusion: Dentures made using polyvinyl siloxane final impression material showed higher mean retention values of complete denture retention than zinc oxide eugenol final impression material. |
