Dental MaterialsA wax pattern made in the mouth will shrink appreciably as it is cooled to room temperature because the coefficient of thermal expansion of wax is very high.(This is the property which describes the thermal energy transport in watts per second through a specimen 1cm thick with a cross sectional area of 1 cm2 when the temperature differential between the surfaces of the specimen perpendicular to the heat flow 10 K) Co efficient of thermal expansion is defined as the change in length per unit of the original length of a material when its temperature is raised 10K.

Dental MaterialsCompomers are indeed known as Polyacrylic acid Modified Composite Resins (PMCRs). They are characterized by their ease of placement, minimal shrinkage, and ability to be shaped and polished after curing. These properties make them a popular choice for dentists due to their user-friendliness and good handling characteristics.

Dental MaterialsTemporary cementing materials are used for trial of the temporary appliance for a few days to get patient approval and to ensure it has suitable consistency and can be easily dislodged during permanent cementation.
