When themal[)0sed teeth have been brought into position theirrounded and unworn cutting edges are apt to contraststrongly with the abraded edges of their neighbors. By sodressing the incising edges of the unworn teeth as to resem-ble those next to them, greater harmony of expression willresult. Fig. 162 illustrates a case in which the worn conditionand varying length of the lower anterior teeth presented avery unsightly appearance, and Fig. 163 represents theimprovement made by reducing the length of certain onesand straightening the edges of others by ImprovLiiiLiit b\ Fig. 163.
