Skeletal and dental modifications produced by the Bionator III appliance

The therapeutic results of a functional orthopedic treatment with a Balters' Bionator III appliance were evaluated. The sample group included 39 white growing subjects with a dentoskeletal Class III malocclusion. A 2-year study compared results with a control group. The results showed that the Bionator III is effective, especially when the malocclusion is mainly the result of a midfacial deficiency and when there is a hypodivergent growth pattern.
