Abstract

It is of interest to document the accuracy, time dependent dimensional stability and displacement to load for 5 types of inter-occlusal recording materials. We used cad bite paste, putty, lab putty, pattern resin and poly tray acrylic material in this study. A total of 25 samples were fabricated to evaluate the accuracy and dimensional stability. The amount of displacement was calculated by applying displacing force on the bite registration materials till they fractured using Instron 3000 UTS machine. Statistical analysis of the data shows that CAD bite paste has the maximum amount of accuracy and dimensional stability whereas pattern resin showed the least amount of displacement to applied force. Thus, we report that CAD bite registration material displayed best results in terms of accuracy and dimensional stability and moderate results in terms of displacement to force.

Highlights

Phillip Pfaff was the first to record interocclusal relations using natural waxes in 1756 [2,3,4,5]
The accuracy and dimensional stability values were maximum in case of CAD bite bite registration paste followed by putty, lab putty, pattern resin and poly tray material respectively in both the directions mesio distally as well as bucco lingually (Table 1, Table 2 and Table 3)
The maximum displacement to force was seen in case of putty material suggesting that it will have the maximum bounce back during mounting of casts followed by CAD bite paste, lab putty, pattern resin and poly tray material

Summary

Introduction

Phillip Pfaff was the first to record interocclusal relations using natural waxes in 1756 [2,3,4,5]. This led to the development of various different bite materials and other impression materials that have been modified to give better handling characteristics. The ideal prerequisite for fabrication of any prosthesis is accurate articulation of the casts [1], [11]. Any type of restoration can be deemed successful only when it can replicate or transfer the accurate interocclusal record. There are mainly 3 reasons for development of inaccuracies while recording interocclusal record [9] (1) the biologic characteristics of ISSN 0973-2063 (online) 0973-8894 (print)
