Al ano de tratamiento ortopedico se observo un aumento en la longitud efectiva de la mandibula aun con hipoplasia utilizando ambas tecnicas, pero particularmente la terapia con las Pistas Planas, con diferencias estadisticamente significativas corroborando la posicion adelantada lograda del Pogonion en el plano sagital.
As mentioned earlier, the use of this technique would result in an accentuated projection of the pogonion, so another retrusion/impaction genioplasty surgery would be necessary.
As for the observed deficient mandibular projection values (projection of lower lip, soft tissue B point and soft tissue pogonion), the reason could either be the insufficiency of soft tissue thicknesses, skeletal inadequacies, lower lip exerting pressure during function or backwards rotation of the mandible.

The nose showed equal forward growth in both groups, but the soft-tissue pogonion was significantly further anteriorly in the treated group.
Mandibular retrognathism was evaluated in accordance with the position of the pogonion when the virtual imaginary line between the vermilion line and the chin on a patient sitting in a Frankfort horizontal position is taken into consideration.
Using advancement genioplasty, Pogonion (Pog) was moved 10.0 mm horizontally forward and 2.0 mm vertically upward.
A pesar de esto, la medida Distancia Pogonion perpendicular a N mostro numericamente una disminucion marcada de 6,41 mm en el 2009 a -16,82 mm en el 2012, posiblemente debido a una posicion mas caudal de la cabeza en la ultima toma, la cual no altero el avance que se observo clinicamente en el menton.
El perfil se determina usando los puntos en tejidos blandos de glabela, subnasal y pogonion; formando asi una convexidad posterior, concavidad anterior o una linea recta.
La convexidad facial corresponde a la distancia en milimetros medida desde el punto A de Downs, ubicado en la zona mas concava de la linea que une la espina nasal anterior con la cresta del proceso alveolar superior, al plano facial, definido entre los puntos Nasion (N) y Pogonion (Pg) (Figura 1).
Que el plano de Camper, determinado por la linea que une la parte media del trago y la parte media externa del ala de la nariz, senala con mucha aproximacion el plano de oclusion y que el plano mandibular establecido entre el punto gonion y el punto pogonion es un reparo natural facil de identificar.
