From: The retrieval of unerupted teeth in pedodontics: two case reports
Ten months after surgery; when the second molar was erupting, and the first molar was impacting against it (as seen in the orthopenthomograph, a), it was decided to wait for the eruption of the second molar (b) before continuing the treatment. So the lingual arch was eliminated to avoid the mesialization of the second molar.
