Which of the following are advantages of laboratory-processed composite restorations over directly placed composites?
1)The restoration is denser.
2)The restoration polymerizes more completely.
3)More stress is created internally on the composite and the walls of the cavity preparation.

The restoration is denser,polymerizes more completely,and is tougher.Less stress is created internally on the composite and the walls of the cavity preparation because polymerization shrinkage occurs outside of the mouth,and then the restoration is cemented with a thin layer of resin cement.Shrinkage from the thin layer of resin cement is much less than would have occurred with a composite that is cured within the tooth.
