Modified fixed nanobite tandem appliance for rapid correction of developing Class III malocclusion.

Aim: Rapid correction of developing Class III malocclusion in pediatric patients using a method with decreased reliance on patient compliance and increased patient comfort.

Method: The modified fixed nanobite tandem appliance (MFNTA) consists of three components, two fixed and one removable. The maxillary fixed appliance consists of a nickel-titanium fixed maxillary expander and a soldered buccal arm used for Class III elastic traction. The mandibular appliance consists of modified fixed nanobite and buccal headgear tubes welded to the mandibular first molar band for facebow attachment.

Result: Pre- and posttreatment records revealed significant skeletal improvement without increase in the vertical dimension and marked improvement in facial balance and esthetics.

Conclusion: MFNTA has the potential to be an effective tool in the treatment of developing Class III malocclusion and relief of the psychologic trauma caused by an anterior crossbite.
