Adhesion strength of brackets repeated bonding in the same surface of enamel and reconditioned with different techniques
Descripción del Articulo
Bonding failures of brackets and the repositioning of them occur quite often during the orthodontic treatment. Upon this situation, the professional may choose to stick the same bracket or bond a new one. The purpose of this study was to evaluate changes of the bonding strength of reconditioned brac...

Adhesion strength of brackets repeated bonding in the same surface of enamel and reconditioned with different techniquesFuerza de adhesión de brackets reacondicionados con diferentes técnicas adheridos repetidas veces en la misma superficie del esmalteLuque Luque, Hugo JavierPérez Vargas, Luis FernandoCarhuamaca León, Gregorio JavierCoronado Tamaríz, Marco AntonioAdhesiónBrackets reacondicionadosResistencia al cizallamiento.BondingReaconditioned bracketsShear bond strength.Bonding failures of brackets and the repositioning of them occur quite often during the orthodontic treatment. Upon this situation, the professional may choose to stick the same bracket or bond a new one. The purpose of this study was to evaluate changes of the bonding strength of reconditioned brackets with direct flame, microetching and new brackets attached several times on the same tooth surface in vitro. 60 healthy human premolars extracted for orthodontic reasons were randomly assigned to 3 groups: Group I reconditioned brackets with air abrasion; Group II: reconditioned brackets with flame; Group III: new brackets. All brackets were bonded with resin No Mix (Prime Dental Manufactuing INC). Initially, new brackets were bonded to all groups to determine initial bonding strength (first shear test), then were subjected to four tests using a universal testing machine. The results showed that bonding strength decreased in relation to the number of shear tests, however, reconditioned brackets with microetching showed significantly more adherence force than the new brackets and flames. Apparently, in the fourth share test maximum stress of occurred enamel so the retention of brackets base became irrelevant.Las fallas de adhesión y el reposicionamiento de brackets acontecen muy a menudo durante el tratamiento ortodóntico. Ante esta situación, el clínico puede optar por volver a adherir el mismo bracket del paciente o adherir uno nuevo. El estudio tuvo como objetivo determinar la variación de la fuerza de adhesión in vitro de brackets reacondicionados con las técnicas de flameado, microarenado y de brackets nuevos. 60 premolares sanas extraídos por indicación ortodóntica fueron agrupados aleatoriamente en 3 grupos: grupo I brackets reacondicionados con técnica de microarenado; grupo II: brackets reacondicionados con técnica de flameado y grupo III: brackets nuevos como control. Todos los brackets fueron adheridos con resina de autopolimerizado No Mix (Prime Dental Manufactuing INC). Inicialmente, brackets nuevos fueron adheridos a todos los grupos para determinar la fuerza de adhesión inicial (primer ensayo de cizallamiento); luego fueron sometidos hasta tres ensayos más utilizando una máquina universal de fuerzas. Los resultados mostraron que la fuerza de adhesión disminuyó en todos los grupos conforme al número de ensayos de cizallamientos, sin embargo, los brackets microarenados mostraron significativamente mayor fuerza de adhesión que los brackets flameados y nuevos. Aparentemente en el cuarto ensayo de cizallamiento se produjo un estrés máximo de la estructura del esmalte y, en consecuencia, la retención de la base de los brackets dejó de ser relevante.Universidad Nacional Mayor de San Marcos, Facultad de Odontología2008-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/odont/article/view/302510.15381/os.v11i2.3025Odontología Sanmarquina; Vol. 11 No. 2 (2008); 60-65Odontología Sanmarquina; Vol. 11 Núm. 2 (2008); 60-651609-86171560-9111reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/odont/article/view/3025/2545Derechos de autor 2008 Hugo Javier Luque Luque, Luis Fernando Pérez Vargas, Gregorio Javier Carhuamaca León, Marco Antonio Coronado Tamarízhttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/30252020-03-23T13:32:34Z |
