This in vitro study was aimed to compare the scannability, dimensional stability of CAD bite material with two other IPS contrast sprayed elastomeric bite registration materials and to evaluate and obtain the most accurate and stable bite registration material among the three elastomers.

Methods

Samples were made in CA Dbite, polyether and polyvinysiloxane bite registration materials and scannability and dimensional stability were compared. These samples were scanned using 3 Shape dental scanner. The images were imported into the software using the Raster image tool.

Results

CAD bite had the highest value for scannability than polyether and vinyl polysiloxanes which was found to be highly significant. Among IPS contrast sprayed elastomeric bite registration materials polyether was better than VPS. The polyether showed least dimensional stability compared to polyvinylsiloxanes and CAD bite though the results were insignificant.
