CASE REPORT The upper second molars were not erupted yet but it can be seen in the panoramic xray that they were in a good direction for eruption. (Fig. 35 and 36). The final extraoral and profile photographs show a passive lip seal and a larger and prettier smile than at the start of treatment (Fig. 37). 9.
