I think it's fair (not to mention stating the obvious) to say that the more thorough restorations will always consume the most grafts, but patient characteristics also come into play. Sometimes I'm amazed at how much can be done with so few grafts.
Would you like to see some examples of healed trichophytic closures performed by Dr. Rahal? I agree that there seem to be less examples in recent patient photo assortments, but that seems to be a trend lately for most doctors on here. Could people be taking scars for granted? I think those of us who have been around for a while will remember when Dr Rahal's strip scars came under scrutiny and were judged as some of the best. (Probably during the great trichophytic closure boom of '07, or maybe that was '06). I shall try and find some examples for you so you can decide for yourself.
