Dentist now says if I want a screw type implant vs. A cemented one the cost of extra parts get added on. He did not know the extra cost. Strauman.?

Implant Costs. Not sure if you are asking what the costs would be for the parts or if Strauman is a good manufacturer. All major players make a good implant; each is slightly different and it is up to the surgeon to use what they feel comfortable with. Any additional costs for parts are minimal in relation to the entire case, so choose the prosthetic that is best for the situation and pay for the parts.
