“…As a result, there is a higher degree of failure compared to bonding to enamel, and different challengesin adult orthodontics. ( 2 , 3 ). Bond strength is mostly affected by the porcelain type, surface conditioning, bracket material and retention mode, properties of the bonding adhesive, the light-curing source, as well as the skill of the clinician.…”

BackgroundAn increasing demand for esthetic restorations has resulted in an increased use of all-ceramic restorations, such as zirconium. However, one of the challenges the orthodontist must be willing to face is how to increase bond strength between the brackets and various ceramic restorations.Bond strength can beaffected bybracket type, by the material that bracketsaremade of, and their base surface design or retention mode.Aim: of this study was to perform a comparative analysis of the shear bond strength (SBS) of metallic and ceramic orthodontic brackets bonded to all-zirconium ceramic surfaces used for prosthetic restorations, and also to evaluate the fracture mode of these two types of orthodontic brackets.Material and methodsTwenty samples/semi-crowns of all-zirconium ceramic, on which orthodontic brackets were bonded, 10 metallic and 10 ceramic polycrystalline brackets, were prepared for this research. SBS has been testedby Universal Testing Machine, with a load applied using a knife edged rod moving at a fixed rate of 1 mm/min, until failure occurred. The force required to debond the brackets was recorded in Newton, then SBS was calculated to MPa. In addition, the samples were analyzed using a digital camera magnifier to determine Adhesive Remnant Index (ARI). Statistical data were processed using t-test, and the level of significance was set at α = 0.05.ResultsHigher shear bond strength values were observed in metallic brackets bonded to zirconium crowns compared tothoseof ceramic brackets, with a significant difference. During the test, two of the ceramic brackets were partially or totally damaged.ConclusionMetallic brackets, compared to ceramic polycrystalline brackets, seemed tocreate stronger adhesion with all-zirconium surfaces due to their better retention mode. Also, ceramic brackets showed higher fragility during debonding.

“…Seeing that there are many concentration of hydrofluoric acid available on the market and that the literature is not conclusive with regard to its protocol of use 13 , various studies with the aim of investigating the best way to prepare the ceramic surface for the purpose of repairing structural damage or for bonding orthodontic accessories have reported positive results with 10% hydrofluoric acid used for an etching time of 60 seconds 3,9,10,18 . A previous systematic review verified that the best protocol to use referred to the application of 9.6% hydrofluoric acid for 60 seconds 20 .…”

Influence of hydrofluoric acid etching time and concentration on shear bond strength of metal brackets to ceramic surfacesInfluência do tempo e concentração do ácido fluorídrico na resistência de união do braquete metálico à superfície cerâmica How to cite: Andrade CGS, Carneiro DPA, Nabarrette M, Correr AB, Valdrighi HC. Influence of hydrofluoric acid etching time and concentration on shear bond strength of metal brackets to ceramic surfaces. Rev Odontol UNESP. 2019;48:e20190102.Introdução: O tratamento de superfície prévio a colagem de braquetes a cerâmica com ácido fluorídrico, é indicado devido a sua capacidade de promover alterações morfológicas necessárias para a adesão. Objetivo: Avaliar a resistência de união ao cisalhamento (RUC) de braquetes metálicos unidos à superfície cerâmica feldspática sob a ação do ácido fluorídrico (AF), em diferentes concentrações (5% e 10%) e tempos de aplicação distintos (30 e 60 segundos). Material e método: Foram utilizados quatro blocos metálicos em níquel-cromo, que receberam a aplicação de cerâmica feldspática, onde foram colados 80 braquetes metálicos (Abzil/3M), divididos em 4 grupos conforme o condicionamento ácido (n=20). Foram condicionados com ácido fluorídrico 5%, por 30 e 60 segundos (AF5/30 e AF5/60) e ácido fluorídrico 10%, por 30 e 60 segundos (AF10/30, AF10/60). O compósito resinoso utilizado foi o Transbond XT (3M) e na superfície cerâmica foi mantido a presença do glazer. Os espécimes foram posicionados na máquina de ensaio universal Instron 4411 (Instron Corp, EUA) com um cinzel adaptado, para teste de cisalhamento, com velocidade de 1mm/min. Os dados foram submetidos a análise de variância (ANOVA) e o Índice de Remanescente Adesivo (IRA) foi avaliado. Resultado: No tempo de 30 segundos não ocorreu diferença significativa para as concentrações de 5% e 10% do ácido fluorídrico. No tempo de 60 segundos, para a concentração de 10% houve uma força de cisalhamento significativamente maior (p<0,05). O IRA apresentou predominância dos escores 1 e 2. Conclusão: Concluiu-se que o ácido fluorídrico 10% apresentou os maiores valores de resistência de união ao cisalhamento em 60 segundos de condicionamento, enquanto, o ácido fluorídrico 5% não demonstrou diferença significativa entre os tempos. Descritores: Condicionamento ácido; cerâmica; resistência ao cisalhamento; braquete ortodôntico. AbstractIntroduction: Surface treatment prior to bonding ceramic brackets with hydrofluoric acid is indicated because of its ability to promote morphological changes necessary for adhesion. Objective: To evaluate the shear bond strength (RUC) of metal brackets bonded to the feldspar ceramic surface under the action of hydrofluoric acid (AF), in different concentrations (5% and 10%) and different application times (30 and 60 seconds). Material and method: Four nickel-chrome metal blocks that received an application of feldspathic ceramic were used, to which 80 metal brackets (Abzil/3M) were bonded and divided into 4 Groups (n=20) according to the acid etching procedure.

“…All the samples were embedded in acrylic (Orthodontic Resin, Item # 040–013, Great Lakes Orthodontics Ltd., Tonawanda, NY), placed in mounting blocks, and sandblasted with 50 μ m aluminium oxide particles at 30 psi for 4 seconds in a Basic Meter Sandblaster (Renfert Corp, Hilzingen, Germany). The ideal protocol for air abrasion is sandblasting with aluminium oxide particles for 4 sec at 2.5-bar pressure (36.5 psi) [ 16 ].…”

This study evaluates tensile bond strength (TBS) of metal orthodontic attachments to sandblasted feldspathic porcelain and zirconia with various bonding protocols. Thirty-six (36) feldspathic and 36 zirconia disc samples were prepared, glazed, embedded in acrylic blocks and sandblasted, and divided into three groups according to one or more of the following treatments: hydrofluoric acid 4% (HF), Porcelain Conditioner silane primer, Reliance Assure® primer, Reliance Assure plus® primer, and Z Prime™ plus zirconia primer. A round traction hook was bonded to each sample. Static tensile bond strength tests were performed in a universal testing machine and adhesive remnant index (ARI) scoring was done using a digital camera. One-way ANOVA and Pearson chi-square tests were used to analyze TBS (MPa) and ARI scores. No statistically significant mean differences were found in TBS among the different bonding protocols for feldspathic and zirconia, p values = 0.369 and 0.944, respectively. No statistically significant distribution of ARI scores was found among the levels of feldspathic, p value = 0.569. However, statistically significant distribution of ARI scores was found among the levels of zirconia, p value = 0.026. The study concluded that silanization following sandblasting resulted in tensile bond strengths comparable to other bonding protocols for feldspathic and zirconia surface.
