| IOR – interocclusal registration material; D – dimensional change; OD – original dimensions of the die. Dimensional change D (%) = (X−Y)/X ×100, where X is the original standard measurment of coordinates in the die and Y is the observed average measurements of coordinates on the samples in particular group; dimensional change D (mm) = X−Y. | ||||||||
