Fixed functional therapy with an anterior bite plane

This clinical case report describes the treatment of Class II tendency in a patient using fixed functional appliance therapy. The appliance used was the fixed flat bite plane, consisting of an incisal acrylic located palatal to the maxillary anteriors that connected to maxillary first molar bands via heavy-gauge wires. The case reviewed involves a white male, age twelve, four months at the beginning of treatment. The patient exhibited a Class II end on molar relationship skeletal pattern with an ANB of 3 degrees and corresponding incisal overjet of 2mm, with 90% overbite. At the conclusion of treatment, fixed functional bite plane therapy resulted in improved overbite, molar canine class I relationship. The results of this case suggest use of the fixed appliance can be successful in improving function, esthetics and increased stability of post treatment both dentally and skeletally in the Class II tendency patient with severe overbite with minimal patient compliance.
