Efficacia degli apparecchi funzionali associati alla trazione extraorale nel trattamento delle malocclusioni di II classe : parte 2.

Objectives: The effectiveness of functional appliances (FJO) in association with extraoral traction (EOT) compared to functional appliances only in the skeletal correction of class II malocclusion in growing patients was evaluated. Materials and methods: A literature review of the last 10 years was performed: the articles selection (RCT, CCT, meta-analysis) was based on explicit inclusion and exclusion criteria. Results: We selected only three articles: the FJO + EOT treatment produced statistically significant skeletal effects in two of three samples for the mandibular growth, in one of three samples for the maxillary one. Conclusions: The FJO + EOT treatment may produce slightly greater short-term skeletal effects than FJO treatment alone. More clinical trials are needed to prove this hypothesis.
