Abstract

AIM: The aim of this study consists in comparing the two-step treatment with that performed in a single-step in adolescent patients. MATERIALS: Study design: This paper is a critical review of the literature with a systematic approach. The search for scientific articles was performed on the US National Library of Medicine database using the PubMed service. Keywords set: "Early treatment Class II OR 1-phase orthodontics OR orthodontic timing Class II". From the initial screening 20 articles were selected of which the full text has been researched and evaluated. CONCLUSION: We can assume that both the one- and two-step treatment are effective in correcting Class II malocclusion, with no significant difference of outcome, except for the incidence of incisor trauma, which was significantly lower for the early treatment group.
