Resumen


Introducción y Objetivo: En la maloclusión clase II, una opción de tratamiento es la alteración del crecimiento mandibular mediante el uso de aparatología de ortopedia funcional. Describir los cambios en la morfometría y morfología condilar y los cambios clínicos después de un año de uso de Pistas Indirectas Planas Compuestas en pacientes con maloclusión clase II.

 

Materiales y métodos: Con Tomografía Computarizada Cone-Beam y revisiones clínicas fueron evaluados 8 pacientes entre 7 y 10 años, antes (T1) y un año después (T2) del uso de Pistas Indirectas Planas Compuestas, describiendo los cambios en morfología y morfometría condilar en los planos axial, sagital y coronal, así como cambios clínicos.

 

Resultados: Las dimensiones latero-medial en el corte axial derecho e izquierdo y coronal derecha presentaron cambios estadísticamente significativas (p< 0,05). En el corte sagital la forma predominante fue la redondeada en un 100% en ambos cóndilos antes y después del tratamiento. En el análisis clínico el overjet disminuyó 2,88 ± 1,51 mm con el uso del aparato.

 

Conclusiones: En este estudio se observó que la morfología condilar fue simétrica bilateralmente en todos los cortes. Luego de un año de tratamiento con Pistas Indirectas Planas Compuestas, se observó aumento bilateral de la dimensión latero medial condilar (cambios morfométricos), disminución del overjet, y el overbite, no se observaron cambios en la morfología condilar. De acuerdo a estos resultados, las Pistas Indirectas Planas Compuestas pueden ser una alternativa de tratamiento para las maloclusiones clase II.

 

Condylar changes by Planas Indirect Compound Tracks on Class II malocclusion evaluated with Cone Beam

 

Introduction and Objective:  In malocclusion class II, a treatment option is the alteration of mandibular growth through the use of functional orthopedic appliances.To describe the changes in the condylar morphometry and morphology and clinical changes after a year of use of Planas Indirect Compound Tracks (PIPC) in patients with class II malocclusion.  Materials and methods: Through tomography CT Cone - Beam and clinical reviews were assessed 8 patients with ages between 7 and 10 years, before (T1) and after a year (T2) the use of PIPC, describing changes in condylar morphology and morphometry in planes axial, coronal and sagital, as well as dental clinical changes.  Results: Measurements right and left latero-medial in the axial cut and right latero-medial in the coronal cut showed statistically significant differences (p < 0,05) between T1 and T2. In the sagital cut the predominant form was the rounded 100% in both condyles before and after treatment. Clinical analysis the overjet decreased 2.88 ± 1.51 mm with the use of the appliance.  Conclusions: In this study we observed that the condylar morphology was bilaterally symmetrical in all courts. After a year of treatment with Planas Indirect Compound, increased bilateral dimension latero medial condyle (morphometric changes), decreased overjet and the overbite was observed, no changes were observed in the condylar morphology. According to these results, Planas Indirect Compound Tracks can be an alternative treatment for Class II malocclusion.  Keywords: Malocclusion Angle Class II, Cone-Beam Computed Tomography, Mandibular Condyle, Planas Indirect Compound Tracks
