Introduction: The success of any prosthetic rehabilitating treatment depends on the precise mounting of casts in the articulator. However a major source of error is while taking the registration records and transferring them to the articulator. These errors can be minimized by proper selection of the materials by knowledgeable application of their properties.

Aim: The present study was conducted to find and compare the dimensional stability of polyether and addition silicone bite registration pastes, 1 hour after making of interocclusal record.

Materials and Method: Materials used in the study are polyether bite registration paste (Ramitec 3M) and addition silicone bite registration paste (O – Bite – DMG). A total of 40 specimens (20 specimens from each material) were made which were divided equally into 2 groups. A metal die with two sets of parallel lines in the depression of the die created a square of 1cm in its centre and two points Point A and Point B in the right corners of the square were selected for measurements. The measurements on the die were compared with those of specimens of two groups and %dimensional change of each group was calculated and analysed statistically.

Result: The percentage dimensional change of polyether bite registration paste had a mean of 0.3088cm while addition silicone bite registration paste had a mean of 0.1911cm.

Conclusion: The study concluded that the dimensional stability of addition silicone bite registration pastes was more than polyether bite registration pastes and the results were statistically significant.
