Rapid maxillary expansion is one of the most highly respected procedures in contemporary Orthodontics. The potential to orthopedically expand the maxilla favored correction of several occlusal changes. Since rapid expansion was first introduced as an orthodontic procedure, a number of appliances and modifications have been suggested in the literature. Among these, premolars rigidly connected by wires instead of banding procedures, as advocated by Haas years ago, have been proposed. In this scenario, the following question arises: Is there any difference in root resorption rates between banded and non-banded teeth, since the level of force delivered to teeth is different in both situations? In order to answer this question, Brazilian researchers conducted a clinical trial1 to compare root resorption when bands and wires are used during rapid maxillary expansion (Fig 1). The authors concluded that both procedures have the same risk of developing external root resorption. Thus, it is the orthodontist’s choice whether to connect teeth by wire or band when performing rapid maxillary expansion.
