The ease of use, speed & accuracy with which I am able get my brackets positioned for optimal fit is incredible! This system has allowed me as an orthodontist/ortho assistant so much more efficient time management during treatment planning sessions by getting all our patients' info into one place (the patient's case file). It also allows us at times when we are having difficulty finding that perfect match between tray size'; shape etc., it can be very helpful if you have some general knowledge about what looks good aesthetically but do not want too many details from your computer screen like most programs out there today provide because they take up way TOO MUCH space!! Having this program makes life easier than ever before. We would love nothing better then another year or two without any problems being reported regarding these products. ! There really isn't anything i dislike.
