Computer tomographic and radiographic changes in the temporomandibular joints of two young adults with occlusal asymmetry, treated with the Herbst appliance.
Two young patients, one female and one male, with asymmetric occlusal deviation and extreme Angle Class II division 1 malocclusions were treated with the Herbst appliance after cessation of endochondral growth (union of the radius epiphysis). During treatment, computer tomographic (CT) scanning and orthopantomograms of the temporomandibular joints (TMJs) revealed, as a result of bone modelling, asymmetrical new bone formation as a double contour on the distocranial part of the condyles. The treatment results were followed for more than 2 years and the new bone was found to be stable.
