Temporary Crown Fitting, How Long, Single Visit?

Hi, I had a crown lengthening procedure and am going to have temporary crowns put on very soon. They wil be on my front two incissors, anteriors, and canines, so on my top 4-6 teeth total. My mouth has completely healed from the crown lengthening, and on last visit, the dentist took impressions of my teeth. I was led to believe that when I return in a couple weeks, they will place the temporary crowns on..Is this a reasonable assumption? Can they place 4-6 individual crowns in one visit, and how long per tooth about? I have just been through so much prep for this, and been waiting so long to get a decent smile so kind of impatient! Thanks for any input!
