Abstract: The cementation of metal brackets was an essential aspect of successful orthodontic treatment, as the adhesive strength against shear forces determined their stability during treatment. Various national and international studies analysed the effectiveness of different cements, such as orthodontic resins and glass ionomers, showing variations in the adhesive strength achieved. Research such as that conducted by Chumacero, Huaita and Aguilar showed that, although some cements offered higher resistance values, the differences were not always statistically significant. Furthermore, multiple factors were identified that influenced adhesion, such as the type of bracket base, enamel preparation, the pressure exerted during cementation, and the patient's clinical condition. Likewise, the need to achieve adhesion that is strong enough to maintain the brackets during treatment, but also safe enough to allow removal without damaging the enamel, was highlighted. Studies such as those by García and Herrera emphasised the importance of the bracket base and the type of resin used, while Fraga and Spaccesi evaluated the effects of pre-conditioning and concluded that there were no significant differences between techniques or concentrations applied. Overall, the evidence supported the importance of selecting an adhesive system that is balanced in strength, safety and practicality, highlighting the need for further standardised research to improve clinical efficacy.
