Effect of self-etching primer/adhesive and conventional bonding on the shear bond strength in metallic and ceramic brackets
INTRODUCTION Bracket debonding from the tooth surface is a common problem in fixed orthodontics. The aims of the present study were to assess the bond strength and failure sites in two ways of bonding technique, with metallic and ceramic brackets. MATERIALS AND METHODS One hundred premolars were assigned to 4 groups of 25 each: Group A, metallic brackets/conventional procedure; Group B, metal...
متن کاملEffect of enamel surface treatment on the bond strength of metallic brackets in rebonding process.
Bond failure after rebonding for newly placed brackets can be reduced by appropriate enamel surface treatment. This in vitro study investigated the effect of two enamel surface treatments on the bond strength of metallic brackets in the rebonding process. After debonding the brackets and removing the residual adhesive on the enamel surface of 50 upper premolar teeth, the teeth were divided into...
متن کاملEffect of etching time and light source on the bond strength of metallic brackets to ceramic.
This study evaluated the bond strength of brackets to ceramic testing different etching times and light sources for photo-activation of the bonding agent. Cylinders of feldspathic ceramic were etched with 10% hydrofluoric acid for 20 or 60 s. After application of silane on the ceramic surface, metallic brackets were bonded to the cylinders using Transbond XT (3M Unitek). The specimens for each ...
متن کاملComparison of shear bond strength of the stainless steel metallic brackets bonded by three bonding systems
Introduction: In orthodontic treatment, it is essential to establish a satisfactory bond between enamel and bracket. After the self-etch primers (SEPs) were introduced for the facilitation of bracket bonding in comparison to the conventional etch-and-bond system, multiple studies have been carried out on their shear bond strengths which have yielded different results. This study was aimed at co...
متن کاملeffect of adhesive type on the shear bond strength of metal brackets to two ceramic substrates
increased number of adult patients requesting orthodontic treatment result in bonding bracket to ceramic restorations more than before. the aim of this study was to evaluate and compare the shear bond strength of orthodontic brackets bonded to two types of ceramic bases with conventional orthodontic bonding resin and a new nano-filled composite resin.twenty four feldespathic porcelain and 24 li...
