Can a protein model, i.e. designed using abintio method, be used as a template for the same sequence in modeller to obtain better refined structure?

I've gone through some papers where the similar method was used i.e. a structure defined by abintio was used as a template for the same sequence to obtain better refined structure. I would like to...
