There are many orthodontic cephalometric analyses available. The emphasis in treatment planning has traditionally been hard tissue focused. This study evaluates a Soft Tissue Arc used in treatment planning. 30 profile images were morphed by 5 orthodontic residents and 5 orthodontic faculty. No statistically significant difference was observed between the morphing of the orthodontic faculty and residents. These same images were changed to match ideal values from a Soft Tissue Arc drawn from nasion with the center at center "O". The Soft Tissue Arc changed the pictures differently than the orthodontic experts, however, there was no statistical difference in the final placement of soft tissue pogonion. These pairs of images (expert morphing vs Soft Tissue Arc changes) were then rated as more attractive or less attractive on a visual analogue scale by 5 orthodontic residents, 5 dental school faculty and 5 laypersons. Across the board, the images morphed by the experts received better ratings than the images changed by the Soft Tissue Arc. Laypersons were considerably less critical in their judgments, and overall gave higher ratings.
