  Introducción: El sistema cráneo-cervicomandibular necesita de factores genéticos, ambientales y funcionales para su desarrollo. La ausencia de estímulos funcionales genera alteración en el crecimiento y mal oclusiones.

  Objetivo: Evaluar los cambios en las dimensiones de los arcos en pacientes con dentición primaria y mordida profunda entre 3 y 5 años, como resultado del tratamiento temprano con ortopedia funcional.Materiales y Métodos: Muestra de 20 niños, entre 3 y 5 años de edad, con dentición decidua completa, mordida profunda, arcos estrechos y relación molar con plano terminal recto o escalón distal, que acudieron a la Universidad del Valle. Se midió en modelos en yeso: Longitud, ancho intercanino, ancho intermolar, perímetro, overbite y overjet. Posteriormente a todos los pacientes se les colocaron pistas directas dePlanas elaboradas de forma indirecta, se les realizó desgaste selectivo y reorientación masticatoria. Pasados 6 meses de tratamiento se realizaron las segundas mediciones.Resultados: En promedio el Overbite inicial de los participantes fue de 87,95%. Se encontró que el Overbite final de los pacientes fue en promedio del 25%. Se encontró diferencias entre los dos tiempos de medición para todas las variables, aunque para el perímetro superior no fueron estadísticamente significativas. La longitud superior y el ancho intermolar tuvieron el mayor porcentaje de cambio.Conclusiones: Las pistas directas de Planas contribuyen a cambios significativos en las dimensiones de los arcos dentales, cuando se implementa como tratamiento temprano para la mordida profunda y/o distoclusiónen la dentición decidua.

  Introduction: The skull cervico mandibularsystem needs of genetic, environmentaland functional factors for development.The absence of funcionals stimuli generatechange in growth and malocclusions.Objective: To evaluate the changes in thedimensions of the archs in patients withprimary dentition and deep bite between 3and 5 years, as a result of early treatmentwith functional orthopedic.Materials and Methods: Sample 20 children,between 3 and 5 years old, with completeprimary dentition, deep bite, narrowarches, molar ratio straight terminal planeor distal step, who attended the Universidaddel Valle. It was measured in plastercasts: Length, width intercanine, intermolarwidth, perimeter, overbite and overjet.Subsequently all patients were placed Planasdirect Tracks elaborate indirectly, Heunderwent selective grinding and chewingorientation. After 6 months of treatment thesecond measurements were made.Results: The average initial overbite ofthe participants was 87.95%. It was foundthat the final overbite of patients was inaverage 25%. Differences between thetwo measurement times for all variableswas found, although the upper perimeterwere not statistically significant. The upperlength and width intermolar had the highestpercentage of change.Conclusions: Direct Planas tracks contributingto significant changes in thedimensions of the dental arches, when itimplemented as early treatment for deep bite and/or distoclusion in the primarydentition.

After 6 months of treatment the second measurements were made.Results: The average initial overbite of the participants was 87.95%. It was found that the final overbite of patients was in average 25%. Differences between the two measurement times for all variables was found, although the upper perimeter were not statistically significant.
