ABSTRACT

Aim To evaluate the dimensional accuracy, flow and melting points and setting temperatures of different combinations of modelling mixed with solidus wax in varied proportions Materials and Method Sheets of modelling (M) wax and solidus (S) wax were cut into samples of standardised dimensions of 4.5x4.5 cm and were divided into 5 groups. Waxes were heated and their melting point and their setting temperatures were recorded. The flow of waxes followed by evaluation of their dimensional stability was done. Results Performing this study showed that the shrinkage of 1M:2S combination of waxes is less on comparing with only Solidus wax which showed 1 mm of shrinkage. Conclusion It can be concluded that by incorporating modeling wax and solidus wax at a proportion of 1:2 into a mixture, one can obtain a material with the benefits of low shrinkage, adequate flow and good strength. Still further studies would be required to confirm the above results. Keywords: Modelling Wax, Solidus Wax, Dimensional Accuracy, Flow, Melting Point
