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

Table 2

The dimensional changes (mean and standard deviation) of the three denture base materials over time.

Base material	Time
	After 4 months		After 8 months		After 12 months
	Mean	SD	Mean	SD	Mean	SD
Acrylic resin fabricated by conventional technique	1.52	0.014	1.56	0.018	1.59	0.02
Acrylic resin fabricated by injection moulding technique	1.58	0.019	1.6	0.022	1.63	0.027
Cobalt chrome metallic	1.5	0.01	1.5	0.01	1.5	0.01
