The physical properties of  the compacted  gold(restoration) are probably more greatly influenced by:
There is no evidence that the diﬀerences in physical properties among the various forms of gold are clinically signiﬁcant. The physical properties of the compacted gold (restoration) are probably more greatly inﬂuenced by the competence of the dentist in manipulating and placing the gold material.
