ABSTRACT
Introducción: La técnica de arco recto es una de las técnicas más utilizadas para la corrección de maloclusiones en ortodoncia; sin embargo, el éxito de la técnica radicará en la exactitud en que se posicionan los brackets. Este artículo presenta un protocolo de cementación indirecta, el cual, adicionalmente, permite una mayor accesibilidad a los materiales requeridos para este procedimiento. Objetivo: Presentar un protocolo efectivo y accesible de cementación indirecta. Material y métodos: Para este protocolo se ha utilizado materiales como resina de cementación de brackets (Transbond XT, 3M Unitek, EEUU), aislante de acrílico para separar los brackets del modelo de yeso y silicona líquida, utilizada habitualmente para autos (Kit Silicona, Johnson, Chile), para separar los brackets del soporte termoplástico, el cual fue realizado con silicona termofusible. Conclusión: El protocolo de cementación indirecta permite un buen posicionamiento de los brackets, reduciendo la posibilidad de reposicionar durante las fases de alineamiento y nivelado (AU)
Introduction: The straight arch technique is one of the most used techniques for the correction of malocclusions in orthodontics; however, the success of the technique will lie in the accuracy in which the brackets are positioned in the correct position. This article presents an indirect cementation protocol which additionally allows greater accessibility to the materials required for this procedure. Objective: Present an effective and accessible indirect cementation protocol. Material and methods: For this protocol, materials such as brace cementation resin (Transbond XT, 3M Unitek, USA), acrylic insulator have been used to separate the brackets from the gypsum and liquid silicone model, usually used for cars (Silicone Kit, Johnson, Chile), to separate the brackets from the thermoplastic support, which was made with hot melt silicone. Conclusion: The indirect cementation protocol allows a good positioning of the brackets, reducing the possibility of repositioning during the alignment and leveling phases (AU)

Although fiber-reinforced posts have been widely used, they sometimes fail to obtain sufficient retention because of an extremely large canal space. To address this, several techniques have been introduced including relining of the fiber-reinforced posts. Here, we used a relined glass-fiber post to increase retention and fitness to the root canal in a crown reattachment case. The relining procedure was performed by using an indirect method on the working cast. This case also highlights the esthetic concerns regarding dehydration of the attached crown fragment.

Evaluar el comportamiento clínico de las restauraciones con resinas fotocuradas a través de la técnica indirecta como alternativa para el tratamiento de cavidades complejas en dientes primarios y/o permanentes posteriores jóvenes. Ocho niños que asistieron al Servicio de Odontopediatría "Santa Elena", en Mérida, Venezuela, fueron incluidos en este estudio, reacondicionando un total de ocho dientes, para posteriormente evaluar el comportamiento clínico: estado periodontal, estado pulpar, restauración presente, satisfacción estética del paciente y estado y adaptación marginal de la restauración. Todas las restauraciones fueron evaluadas a los 8 días y a los 3 meses de realizados los tratamientos. Los datos fueron analizados utilizando el paquete estadístico SPSS versión 13.0 (SPSS INC, Chicago, IL, Estados Unidos de América). Se realizó un análisis estadístico descriptivo de todas las variables estudiadas y un análisis cualitativo no paramétrico aplicando el Test Chi-cuadrado y Exacto de Fisher. Al tercer mes del tratamiento se observa que el comportamiento clínico es exitoso en un 100%, excepto la presencia de placa bacteriana (62,5%) y la satisfacción estética del paciente (87,5%). Sin embargo, al aplicar el Test Chi-Cuadrado y Exacto de Fisher no existen diferencias estadísticamente significativas (p=0,302, 0,606 y 0,304). Las restauraciones indirectas con resinas compuestas constituyen una alternativa de tratamiento para dientes primarios o permanentes posteriores jóvenes con cavidades complejas
The aim of this study was to evaluate the clinical behavior of the restorations with resins light cure through the indirect technique like alternative for the treatment of complex cavities in primary and/or permanent posterior young teeth. Eight children who attended the Service of Pediatric Dentistry "Santa Elena", in Mérida, Venezuela, were including in this clinical test, recovering a total of eight teeth, later to evaluate the periodontal state and pulp , is present at or not of biofilm, state and marginal adaptation of the restoration and esthetic satisfaction of the patient. All the restorations were evaluated to the 8 days and the 3 months. The data were analyzed using statistical package SPSS version 13.0 (INC. SPSS, Chicago, IL, United States of America). It was made a descriptive statistical analysis of all the studied variables and a non-parametric qualitative analysis having applied to the Test Chi-square and Exact of Fisher. The third month of the treatment it is observed that the clinical behavior is successful in 100% a, except the presence of biofilm (62.5%) and the esthetic satisfaction of the patient (87.5%). Nevertheless, when applying the Test Chi-Square and Exact de Fisher does not exist statistically significant differences (p=0,302, 0.606 and 0.304). The indirect restorations with compound resins constitute an alternative of treatment for primary or permanent posterior young teeth with complex cavities
