Effect of Different Denture Base Materials and Changed Mouth Temperature on Dimensional Stability of Complete Dentures

Table 3

The dimensional changes of the three denture base materials by temperature changes (after one month of denture insertion).

Base material	Temperature
	Normal mouth temperature		Hot tea at 45°C		Cold drink at 5°C
	Mean	SD	Mean	SD	Mean	SD
Acrylic resin fabricated by conventional technique	1.5	0.01	1.5	0.01	1.5	0.01
Acrylic resin fabricated by injection moulding technique	1.5	0.01	1.5	0.01	1.48	0.009
Cobalt chrome metallic	1.5	0.01	1.6	0.019	1.43	0.004
