Abstract


RESUMEN. Antecedentes: La pérdida prematura de un molar primario conlleva a malposición de los dientes contiguos y del sucesor permanente. El efecto depende de las fuerzas que actúan sobre el diente, que están condicionadas a su vez por el estado de erupción del primer molar permanente. Propósito: Describir una opción de tratamiento para la pérdida prematura de segundos molares primarios hasta la erupción de los primeros molares permanentes. Descripción del caso: El caso clínico presentado involucra la rehabilitación oral de un niño de 5 años de edad que presentaba pérdida prematura de los segundos molares primarios. Se decidió colocar un mantenedor de espacio tipo zapato distal modificado. Se realizaron controles trimestrales y, cuando erupcionaron los primeros molares permanentes, aproximadamente a los nueve meses, se les utilizó como pilares para confeccionar el arco lingual. Conclusiones: El tratamiento propuesto mostró resultados satisfactorios en el mantenimiento del espacio hasta la erupción de los primeros molares permanentes.

ABSTRACT. Background: The premature loss of a deciduous molar leads to malposition of adjacent teeth and the permanent successor. The effect depends on the forces acting on the tooth, which are conditioned at the same time by the grade of eruption of the first permanent molar. Purpose: To describe a treatment option for primary second molar premature loss until first permanent molars erupt. Case description: This clinical case involves the oral rehabilitation of a 5-year-old boy who lost prematurely his primary second molars. The decision was to place a modified distal shoe space maintainer. Controls were performed every three months and when the first permanent molars erupted, approximately nine months later they were used as pillars, to make the lingual arch. Conclusions: The treatment used showed satisfactory results in maintaining the space until permanent first molars erupted.
