In recent years the surgery-first approach in orthognathic surgery has been widely developed, but its execution in cases with extractions has been limited, partly because of the difficulty of predicting the results to be obtained. The present article presents 2 cases of patients with class III malocclusion and with marked proclination of the upper incisors that were treated with surgery-first combined with the extraction of the second maxillary premolars. In addition, it can be seen how through careful treatment planning, the expected results can be appropriately achieved. We describe some treatment considerations while performing this type of therapy.
