Abstract:
A.
Pretreatment Records:
10/08/2004 (age of patient: 13 y 8 m).
Diagnosis:
Hyperdivergent skeletal Cl. II, dental Cl. I with bimaxillary protrusion.
Treatment:
Multibracket appliance with extraction of 14/24/34/44. B. POSTTREATMENT RECORDS: 24/03/2007 (age of patient: 16 y 3 m).
Retention:
Maxillary Hawley plate and mandibular wire bonded from 33 to 44. C. POSTRETENTION RECORDS: 28/01/2009 (age of patient: 16 y 3 m). D.
Clinical Observations:
Consultation for an esthetic problem (bimaxillary protrusion). The extraoral examination revealed a convex, hyperdivergent profile and incompetent lip seal at rest. Endooral examination showed the presence of moderate anterior crowding, bimaxillary protrusion and Cl. I relationships. The status of the dentition and periodontium was satisfactory apart from the first permanent molars.
