Introduction: Dental and skeletal Class III malocclusion can be orthodontically treated in the mixed dentition phase. However, the association of other malocclusion types, such as deep overbite, implies a higher severity of the case. Considering that, it is necessary to use other resources such as a facial mask, which may have its results compromised by insufficient vertical dimension in deep overbite malocclusion. Therefore, anterior tooth displacement and maxillary protraction eventually may be blocked and, as a solution, posterior disocclusion bite plates are commonly used. Nevertheless, what is a viable approach when there is not enough dental support in the posterior region? What to do? Objective: This case report aims to describe how to obtain dental disocclusion for maxillary protraction, during mixed dentition phase, in Class III malocclusions associated with significant deep overbite and few posterior teeth as support.
