Early treatment of hyperdivergent open-bitemalocclusions
Additional Document Info
This article establishes the morphologic attributes that characterize hyperdivergent open-bite (Hyp-OB) subjects, reviews associated etiologic factors, compares the various treatment modalities, and provides a rationale and a possible approach for early treatment. Treatment of Hyp-OB patients must address three-dimensional dentoalveolar and skeletal problems in both jaws. For early treatment to be successful, it must effectively deal with the etiology of the problem and the resulting mandibular skeletal dysmorphology. Of the various treatment approaches, including high-pull headgear, extractions, and bite blocks, the vertical chin cup holds the greatest potential for mandibular skeletal modification. Although early treatment can be theoretically justified based on psychosocial benefits and growth potential, more clinical and experimental research is required to optimize the treatment approach and define the long-term consequences.
