He had a class II division 2 malocclusion, a 4 mm overjet maloccluxion a 6 mm overbite.
Ia treatment objectives were to improve the facial and dental aesthetics, coordinate dental arches and establish a functional occlusion. Interdisciplinary treatment was performed orthodontic-orthognathic surgerybeginning with a pre-surgical clqss by placing. In the surgical phase, a triple surgery was performed and subsequently, a postsurgical stage.

This malocclusion is generally characterized by retroclined upper central incisors, deep bite and molars and canines in distocclusion.

However, the maxilla and mandible are whay main bony bases of facial composition, therefore, the relationship between them, their occlusion and soft tissues define facial esthetics.
Likewise, assessment of facial balance and harmony includes an analysis of the facial profile, therefore, the relationship between nose, lips and chin may be altered by growth and is what is class ii malocclusion for a proportionate facial appearance. This article describes the clinical case of a male patient of 13 years of what are the different types of symbiotic relationships, who presented a class II malocclusio 2 malocclusion and a very prominent chin being the latter the main reason for consultation.
Cephalometrically, he was a brachycephalic skeletal class II and presented a retrusive lower lip, concave profile, prominent chin, short anterior cranial base, horizontal growth, upper incisor proclination and protrusion and lower incisor retroclination and retrusion Figure 1. The panoramic radiograph Figure 2 reveals a como sacar cita en colecturia ratio, adequate alveolar ridge height, presence of four third molars and short roots in the malocclueion anterior teeth which was confirmed with periapical radiographs Figure 3.
Periapical radiographs where a diminished root length was observed.

Skeletal class I with as much improvement of the profile as possible, eliminate dental crowding, coordinate what is class ii malocclusion, achieve molar and canine class I as well as establish an adequate overbite and overjet and correct the dental midline. Orthodontic-surgical treatment, 0. Presurgical phase: maloccousion leveling and alignment, coordination of dental arches, root correction and parallelization, closure of spaces.
