Abstract

The primary objective of the current review is to examine the enamel cracks before and after debonding of metal and ceramic brackets. The variables evaluated are: size, shape, localization of the cracks and the adhesive remnant index. Braces should be removed from the enamel surface, after orthodontic treatment. Removing the brackets may damage the tooth enamel. The risk of enamel damage increases when removing ceramic brackets. Some researchers evaluated different debonding methods in order to find the one that would cause less damage on the enamel and some others evaluated the bond strength of both metal and ceramic brackets showing that enamel cracks are associated with the bond strength. More specifically, it has been demonstrated by some researchers that higher bond strength is correlated with increased number and size of enamel cracks. There are authors reporting that brackets with chemical retantion do not exhibit greater bond strength compared with brackets with mechanical retantion. On the other hand, some authors asserted that brakets with chemical retention produce significantly higher bond strengths than brackets with other types of retention bases
