Comparative Evaluation of Aluwax, Polyvinyl Siloxane, Polyether and Bis-Acryl Bite Registration Material at Different Time Interval: An In-Vitro-Study

Aim: The aim of this study was to evaluate the accuracy and dimensional stability of Aluwax, polyvinyl siloxane, polyether and bis-acrylic bite registration materials at 8hours, 24hours and 48hours.

Materials and Methods: Four commonly used bite registration materials were used in this study which includes Aluwax, Polyvinyl Siloxane (Orange bite), Polyether (Ramitec) and Bis-Acrylic bite registration material (Luxabite). The sample size was 76 (19 in each group). The samples fabricated were then grouped into Group 1- Aluwax, Group 2 – Polyvinyl siloxane bite registration material, Group 3 – Polyether bite registration material and Group 4 – Bisacrylic bite registration material.

Result: Using Student’s paired and unpaired T-test, statistical analysis was performed to determine the material’s accuracy. The results of which were taken at 5% (p>0.05) and 1% (p>0.01) level of significance. While, Kruskal-Wallis and ANOVA were the tests used to determine dimensional stability over time intervals at 5% (p>0.05) and 1% (p>0.01) level of significance. The result was statistically significant for both intra-group at different time intervals and between the test groups for accuracy and dimensional stability.

Conclusion: Polyvinyl siloxane bite registration material exhibited better accuracy and dimensional stability at time interval, followed by Polyether, Bis-Acrylic and Aluwax. Additionally, this research paper found that the dimensional stability was influenced by the time interval, as time increased the dimensional stability of the material decreased.
