this process is how I communicate with patients about their treatment progress. This case is routine in terms of effectiveness, where one series of aligners usually is not quite enough to reach the perfect alignment. This is not unlike braces where numerous adjustments have to be administered. With aligners, however, you are always heading in linear fashion to the end result, whereas braces cause some unpredictable effects that the orthodontist has to harness. Braces are dynamic but not necessarily "faster" in terms of overall treatment time. I always think about the fable of the race between the rabbit and the turtle. The rabbit is fast out of the gate but round all over the place and the turtle is always moving steady to the finish is a direct line. ce
